I am trying to run a Django app on my VPS running Debian 5. When I run a demo app, it comes back with this error:
File "/usr/local/lib/python2.5/site-packages/django/utils/importlib.py", line 35, in import_module

Reading on the web, I learn that Python 2.5 should come with all the necessary SQLite wrappers included. Do I need to reinstall Python, or is there another way to get this module up and running?
It seems your makefile didn't include the appropriate .so file. You can correct this problem with the steps below:
Install sqlite-devel (or libsqlite3-dev on some Debian-based systems)
Re-configure and re-compiled Python with ./configure --enable-loadable-sqlite-extensions && make && sudo make install
Note
The sudo make install part will set that python version to be the system-wide standard, which can have unforseen consequences. If you run this command on your workstation, you'll probably want to have it installed alongside the existing python, which can be done with sudo make altinstall.
I had the same problem (building python2.5 from source on Ubuntu Lucid), and import sqlite3 threw this same exception. I've installed libsqlite3-dev from the package manager, recompiled python2.5, and then the import worked.
I had the same problem with Python 3.5 on Ubuntu while using pyenv.
If you're installing the python using pyenv, it's listed as one of the common build problems. To solve it, remove the installed python version, install the requirements (for this particular case libsqlite3-dev), then reinstall the python version with
pyenv install <python-version>
Then recreate virtualenv if needed.
my python is build from source, the cause is missing options when exec configure
python version：3.7.4
./configure --enable-loadable-sqlite-extensions --enable-optimizations
make
make install
fixed
This is what I did to get it to work.
I am using pythonbrew(which is using pip) with python 2.7.5 installed.
I first did what Zubair(above) said and ran this command:
sudo apt-get install libsqlite3-dev
Then I ran this command:
pip install pysqlite
This fixed the database problem and I got confirmation of this when I ran:
python manager.py syncdb
Install the sqlite-devel package:
yum install sqlite-devel -y
Recompile python from the source:
./configure
make
make altinstall
I found lots of people meet this problem because the Multi-version Python,
on my own vps (cent os 7 x64), I solved it in this way:
Find the file "_sqlite3.so"
find / -name _sqlite3.so
out: /usr/lib64/python2.7/lib-dynload/_sqlite3.so
Find the dir of python Standard library you want to use,
for me /usr/local/lib/python3.6/lib-dynload
Copy the file:
cp /usr/lib64/python2.7/lib-dynload/_sqlite3.so /usr/local/lib/python3.6/lib-dynload
Finally, everything will be ok.
For Python 3.7.8 with Redhat 7 or Centos 7.
Install sqlite-devel
$ yum install sqlite-devel
Compile and install Python3 with sqllite extensions
$ ./configure --enable-optimizations --enable-loadable-sqlite-extensions
$ make install
My _sqlite3.so is in /usr/lib/python2.5/lib-dynload/_sqlite3.so. Judging from your paths, you should have the file /usr/local/lib/python2.5/lib-dynload/_sqlite3.so.
Try the following:
find /usr/local -name _sqlite3.so
If the file isn't found, something may be wrong with your Python installation. If it is, make sure the path it's installed to is in the Python path. In the Python shell,
import sys
print sys.path
In my case, /usr/lib/python2.5/lib-dynload is in the list, so it's able to find /usr/lib/python2.5/lib-dynload/_sqlite3.so.
I recently tried installing python 2.6.7 on my Ubuntu 11.04 desktop for some dev work. Came across similar problems to this thread. I mamaged to fix it by:
Adjusting the setup.py file to include the correct sqlite dev path. Code snippet from setup.py:
def sqlite_incdir:
sqlite_dirs_to_check = [
os.path.join(sqlite_incdir, '..', 'lib64'),
os.path.join(sqlite_incdir, '..', 'lib'),
os.path.join(sqlite_incdir, '..', '..', 'lib64'),
os.path.join(sqlite_incdir, '..', '..', 'lib'),
'/usr/lib/x86_64-linux-gnu/'
]
With the bit that I added being '/usr/lib/x86_64-linux-gnu/'.
After running make I did not get any warnings saying the sqlite support was not built (i.e., it built correctly :P ), but after running make install, sqlite3 still did not import with the same "ImportError: No module named _sqlite3" whe running "import sqlite3".
So, the library was compiled, but not moved to the correct installation path, so I copied the .so file (cp /usr/src/python/Python-2.6.7/build/lib.linux-x86_64-2.6/_sqlite3.so /usr/local/python-2.6.7/lib/python2.6/sqlite3/ — these are my build paths, you will probably need to adjust them to your setup).
Voila! SQLite3 support now works.
This worked for me in Redhat Centos 6.5:
yum install sqlite-devel
pip install pysqlite
sqlite3 ships with Python. I also had the same problem, I just uninstalled python3.6 and installed it again.
Uninstall existing python:
sudo apt-get remove --purge python3.6
Install python3.6:
sudo apt install build-essential checkinstall
sudo apt install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev
wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tar.xz
tar xvf Python-3.6.0.tar.xz
cd Python-3.6.0/
./configure
sudo make altinstall
Is the python-pysqlite2 package installed?
sudo apt-get install python-pysqlite2
Checking your settings.py file.
Did you not just write "sqlite" instead of "sqlite3" for the database engine?
Putting answer for anyone who lands on this page searching for a solution for Windows OS:
You have to install pysqlite3 or db-sqlite3 if not already installed. you can use following to install.
pip install pysqlite3
pip install db-sqlite3
For me the issue was with DLL file of sqlite3.
Solution:
I took DLL file from sqlite site. This might vary based on your
version of python installation.
I pasted it in the DLL directory of
the env. for me it was "C:\Anaconda\Lib\DLLs", but check for yours.
I have the problem in FreeBSD 8.1:
- No module named _sqlite3 -
It is solved by stand the port ----------
/usr/ports/databases/py-sqlite3
after this one can see:
OK ----------
'>>>' import sqlite3 -----
'>>>' sqlite3.apilevel -----
'2.0'
you must be in centos or redhat and compile python yourself，
it is python‘s bug
do this in your python source code dir and do this below
curl -sk https://gist.github.com/msabramo/2727063/raw/59ea097a1f4c6f114c32f7743308a061698b17fd/gistfile1.diff | patch -p1
I was disappointed this issue still exist till today. As I have recently been trying to install vCD CLI on CentOS 8.1 and I was welcomed with the same error when tried to run it. The way I had to resolve it in my case is as follow:
Install SQLite3 from scratch with the proper prefix
Make clean my Python Installation
Run Make install to reinstall Python
As I have been doing this to create a different blogpost about how to install vCD CLI and VMware Container Service Extension. I have end up capturing the steps I used to fix the issue and put it in a separate blog post at:
http://www.virtualizationteam.com/cloud/running-vcd-cli-fail-with-the-following-error-modulenotfounderror-no-module-named-_sqlite3.html
I hope this helpful, as while the tips above had helped me get to a solution, I had to combine few of them and modify them a bit.
i got the same problem, nothing worked for me from the above ans
but now i fixed it by
just remove python.pip and sqlite3 and reinstall
sudo apt-get remove python.pip
sudo apt-get remove sqlite3
now install it again
sudo apt-get install python.pip
sudo apt-get install sqlite3
in my case while installing sqlite3 again it showed some error
then i typed
sqlite3
on terminal to check if it was removed or not and it started unpacking it
once the sqlite3 is installed
fireup terminal and write
sqlite3
database.db (to create a database)
i'm sure this will definately help you
Try installing sqlite like this if you are using FreeBSD.
pkg install py27-sqlite3-2.7.10_6
I had the same problem after installing Python 3.8.11 using asdf
To fix the issue:
I had to install libsqlite3-dev
sudo apt-get install libsqlite3-dev
Then uninstall Python via asdf
asdf uninstall python 3.8.11
And install Python again via asdf
asdf install python 3.8.11
The following worked for Python 3.9 with a virtual environment:
Install the sqlite3 library.
sudo apt-get install libsqlite3-dev
Activate the Python virtual environment.
source env/bin/activate
Copy the sqlite3 file into the Python virtual environment and rename it to support Python 3.9.
cp /usr/lib/python3.8/lib-dynload/_sqlite3.cpython-38-x86_64-linux-gnu.so ./env/lib/python3.9/site-packages
mv ./env/lib/python3.9/site-packages/_sqlite3.cpython-38-x86_64-linux-gnu.so ./env/lib/python3.9/site-packages/_sqlite3.cpython-39-x86_64-linux-gnu.so
Note, we're renaming 38 to 39 in the file name to support Python 3.9.
Download sqlite3:
wget http://www.sqlite.org/2016/sqlite-autoconf-3150000.tar.gz
Follow these steps to install:
$tar xvfz sqlite-autoconf-3071502.tar.gz
$cd sqlite-autoconf-3071502
$./configure --prefix=/usr/local
$make install
I faced this issue with multiple python dependent package while setup in python virtual enironment in Ubuntu.It is because of sqlite binding for our python.
Error I got:
from pysqlite2 import dbapi2 as sqlite3
ModuleNotFoundError: No module named 'pysqlite2'
I resolved it by --enable-loadable-sqlite-extensions=yes
1.) First find your python or python version you used for creating virtual env. I have used python3.8
e.g
$ whereis python
python: /usr/bin/python3.6m /usr/bin/python /usr/bin/python3.8 /usr/bin/python2.7-config /usr/bin/python3.8-config python
$ cd /usr/bin
$ls
python3.8
python3.8-config
Note: there will be many package check for pytho. you will find configure file for each python version, now use specific python version
ox:/usr/bin$ ./python3.8-config --enable-loadable-sqlite-extensions=yes
OR
ox:/usr/bin$ ./python3.8-config --enable-optimizations --enable-loadable-sqlite-extensions
Now, create your virtual env using that python version
e.g
Go the folder where you want to create the virtual env
$ python3.8 -m venv mlwen_jup_env
$ source mlwen_jup_env/bin/activate
Its done, now you can install packages
I ran into this same problem on a NetBSD server. A missing .so file needed to be installed using pkgin. To identify what package to install, I ran
pkgin search sqlite
which had lots of results, including
...
py38-aiosqlite-0.17.0nb1 Async bridge to the standard sqlite3 module
py38-apsw-3.37.0nb2 Python wrapper for SQLite
py38-peewee-3.15.0 Small, expressive ORM for PostgreSQL, MySQL and SQLite
py38-sqlite3-3.8.13nb22 Built-in sqlite support for Python 2.5 and up
py39-aiosqlite-0.17.0nb1 Async bridge to the standard sqlite3 module
py39-apsw-3.37.0nb2 Python wrapper for SQLite
py39-peewee-3.15.0 Small, expressive ORM for PostgreSQL, MySQL and SQLite
py39-sqlite3-3.9.13nb22 Built-in sqlite support for Python 2.5 and up
...
(and other python versions as well). I'm using python 3.9, so py39-sqlite3-3.9.13nb22 was the correct choice in my case. Running
sudo pkgin install py39-sqlite3-3.9.13nb22
fixed the issue for me.
You need to install pysqlite in your python environment:
$ pip install pysqlite
Try copying _sqlite3.so so that Python can find it.
It should be as simple as:
cp /usr/lib64/python2.6/lib-dynload/_sqlite3.so /usr/local/lib/python2.7/
Trust me, try it.

I've been trying to use VS Code's python debugger on Linux (mint), which uses debugpy and it keeps giving the error "No module named '_ctypes'". Installing libffi-dev didn't fix it as suggested elsewhere on SO and neither did reinstalling python and python3; so, I tried installing debugpy through pip:
pip install debugpy
Which installs with no issues. However, both python and python3 commands cannot find the module despite the fact that the module is installed (which I can see when I enter pip list)
python -m debugpy
/usr/bin/python: No module named debugpy
python3 -m debugpy
/usr/local/bin/python3: No module named debugpy
So after trying to reinstall pip multiple times, I tried installing through the pip module
python -m pip install debugpy
/usr/bin/python: No module named pip
python3 -m pip install debugpy
/usr/local/bin/python3: No module named pip
So it seems my pip module is also missing too. It may have something to do with my multiple installations of python3 as it seems that there is one in /bin and in /usr/local/bin and the local installation is the one that gets called with the python3 command according to which python3.
This leads to multiple questions:
Should the pip module be installed in python, and if so how do I install it again?
How can I get the pip command to actually install the modules into python?
How can I ensure that there is only one python3 installation in Linux (mint/ubuntu)?
Thank-you. If it helps answer the question, I do not seem to have a PYTHONPATH variable.
i had same issue but it can be fixed by two methods.
reinstall pip for the latest python version you use.
2.use the version default python version which came with your python install
On ubuntu you can try to do sudo apt install python-pip python3-pip. Also there a couple ways you can try what PIP's documentation recommends: Installation
You can try checking sudo update-alternatives --config python maybe you'll see several python installations there.
Also you can check pip contents to find out what python binary it uses:
$ which pip
/usr/local/bin/pip
$ cat /usr/local/bin/pip
#!/usr/bin/python3
# -*- coding: utf-8 -*-
import re
import sys
from pip._internal.cli.main import main
if __name__ == '__main__':
sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
sys.exit(main())
#!/usr/bin/python3
I tried installing it with pip and it has worked for me. The problem you might have is that it is not installed in the correct version of python (e.g it installs for python2 instead of python3 or it installs in python3.8 instead of python3.9).
What you can do to avoid this problem is to create a virtual environment, as is explained in this link: https://docs.python.org/3/tutorial/venv.html. If you do that, remember to change the interpreter path in VSCode. At the bottom left of the screen there should be the python version that you are using. If you click on it you see different interpreter versions that you can use. Select 'Enter interpreter path' and manually choose the directory where you have saved the new python virtual environment.
It's difficult to narrow down a solution for apparently you have done a mess... To start, do yourself a favor:
Don't touch your System's Python!
Again, it is difficult for me to understand what is the current state of your Python scene... just promise me you'll fix your System's Python 2/3 (i.e, guarantee pip 2/3 there, using your system's package manager (apt, yum, etc)).
Then, start using some virtual environment manager, nowadays we have Pipenv (https://pipenv.pypa.io/), which can be a bit cumbersome at first but -- trust me -- in ~1 hour you'll love it.
Conda (https://docs.conda.io/) is also a great env manager (or the classics (pyenv, venv, etc...)).
...Just pick one and leave your OS' Python alone. You'll see that your issues will not only get simpler to diagnose but you'll also be able to sleep in peace ;)
From this https://docs.python.org/3.4/library/2to3.html it says that 2to3 should be installed as a script alongside the python interpreter. However, in my /usr/bin/ folder there are no 2to3 executable, and running find from / finds no 2to3 executable either. I do however have a folder called lib2to3 at /usr/lib64/python{3.4/2.7}/lib2to3 but containing nothing I found relevant. In python/site-packages/setuptools/ there is a lib2to3_ex.py script, but nothing happens if I run it. How do I get to the point where I can simply type 2to3 upgradethisscripttopython3.py ?
You need to first install the following packages:
apt install 2to3
apt install python3-lib2to3
apt install python3-toolz
For windows just install 2to3
pip install 2to3
Then, You can simply go to that directory your python file is in and type the following command:
2to3 ./filename.py
OR for writing the updated python 3 code to the existing file
2to3 . -w
This last will convert all the python files that are in the directory.
So the solution is that at least not for me, the Tools/scripts files were not automatically installed. On ubuntu this would be solved by installing python-examples which on opensuse is called python-demo
On CentOS (and other RHEL-like distros) you will need to run yum install python-tools, which installs 2to3 to /usr/bin/2to3
On Fedora 29, the python-tools is not providing 2to3. I had to install the development package:
dnf install python3-devel
I found this out by first calling:
dnf whatprovides /usr/bin/2to3
So far I've been using pip install 2to3. Conversions worked like absolute charm!
(I'm on Ubuntu 18.04)
Check if you have the file /usr/bin/2to3-2.7 (or similar). If one exists, then simply create a symbolic link to it with a link name of 2to3 (e.g.: ln -s 2to3-2.7 /usr/bin/2to3).
I work with linux on a servies. And I don't have the root privilege. I installed the python-3.2.3 locally to "/home/sam/install_sam". when I import the tkinter module. I get the following error:
ImportError: No module named _tkinter, please install the python-tk package
I know I need to install the Tkinter module. because I don't have the root privilege. I can't use like the following commands:
apt-get install python-tk
sudo apt-get install python-tk
And I search on goolge. I get tcl/tk from here. I install them use the following commands.
cd ~/Downloads/tcl8.5.11/unix
./configure --prefix=/home/sam/install_sam/tcl
make
make install
cd ~/Downloads/tk8.5.11/unix
./configure --prefix=/home/sam/install_sam/tk
--with- tcl=/home/sam/Downloads/tcl8.5.11/unix
make
make install
cd ~/Downloads/Python3.2.3/
export LD_LIBRARY_PATH=/home/sam/install_sam/tcl/lib:/home/sam/install_sam/tk/lib
export LD_RUN_PATH=/home/sam/install_sam/tcl/lib:/home/sam/install_sam/tk/lib
./configure --prefix=/home/sam/install_sam/python
make
make install
I still got error: INFO: Can't locate Tcl/Tk libs and/or headers. How should I config the tcl/tk for the python
Use CPPFLAGS environment variable to set the include directories for tcl and tk before building Python 3. This has worked for me.
export CPPFLAGS="-I/home/sam/install_sam/tcl/include -I/home/sam/install_sam/tk/include"
Finally. I install tcl/tk and python in a same path. It can work now. the commands as follow:
cd ~/Downloads/tcl8.5.11/unix
./configure --prefix=/home/sam/install_sam/python3
make
make install
cd ~/Downloads/tk8.5.11/unix
./configure --prefix=/home/sam/install_sam/python3
--with-tcl=/home/sam/Downloads/tcl8.5.11/unix
make
make install
export LD_LIBRARY_PATH=/home/sam/install_sam/python3/lib
cd ~/Downloads/Python3.2.3/3
./configure --prefix=/home/sam/install_sam/python3
make
make install
someone can tell me how to config the tcl/tk for python in the first way(mentioned in the question). I'll appreciate it
sudo apt-get install tcl-dev tk-dev
worked for me, although I ended up pulling a docker image and using that instead.
In my case I had import tkinter properly working on my Python3 environment, but I had to use a pre-compiled Python with its own environment (Blender fyi) that didn't include the dependencies (I needed tkinter to run matplotlib).
The fix in my case was very simple:
In the working python, import tkinter and check where it is installed with tkinter.__file__. This will be something like path/to/site-packages/tkinter
Copy the tkinter folder into the site-packagesof your target installation
Then import _tkinter won't work. Again using the file trick, locate the missing .so file, in my Ubuntu was something like `path/to/python3.7/lib-dynload/_tkinter.cpython-37m-x86_64-linux-gnu.so'
Again, copy the .so file into the corresponding lib-dynload of your target installation. Make sure that both origin and target Python versions are compatible.
To make sure that your target python finds the copied files, make sure that the destination paths are listed under sys.path.
Hope this helps!
Cheers,
Andres
For CentOS, this is:
yum install -y tcl-devel tk-devel
Worked on CentOS 7.
In general, I find that where RHEL has *-dev, CentOS has *-devel
I have a Fedora 11 box with MySQL server. Fedora 11 uses python 2.6 internally and python 2.6 is automatically installed on the box. I have created a python virtual-env for version 2.5.5, so that I can run turbogears 1.x application. I have MySQLdb rpm installed on the box (and it works fine with python 2.6).
When I import MySQLdb from within python version 2.6 it imports is successfully. When I import MySQLdb from within the python 2.5.5 virtual-env the import fails (because I have installed virtual-env with --no-site-packages). So, I have to install MySQLdb python as a local package (local to virtual-env).
'easy_install MySQL-python' within the virtual env fails. It downloads the MySQL-python-1.2.3.c1.tar.gz/download, but the 'python setup.py build' fails with error. The same problem occurs when building the MySQL outside of virtual-env.
Is the 'python setup.py build' for MySQL-python trying to link to a library (and am I missing some library)? Or is the downloaded code missing some header files (unlikely)?
Thanks.
S.Mark,
If I were to install MySQL header files, would they mess with the existing rpms?
[Sorry, for being redundant. In essence, MySQL is functional on the machine, MySQL-python is functional for python 2.6, but MySQL-python is not functional from virtualenv for python 2.5.5.]
Thank you for trying to help.

Works! Thanks for all your help.
I installed mysql-devel package (yum install mysql-devel) on the box.
Then did easy_install MySQL-python from within virtual-env (python 2.5.5), and the compilation/installation was successful (with some warnings).
Thanks.
Just to mention for the others that might end up here too,
I solved this error in installing mysql-devel
$ yum install mysql-devel.x86_64
Hope this helps
In case it does not work even after installing mysql-devel package, check the contents of "/usr/include/mysql".
If is empty then its possible that mysql-devel has installed the header files at some pther place, run following command to find
find /usr/include/ -maxdepth 1 -name mysql*
If found, create a symlink like following to fix the problem.
ln -s /usr/include/mysql51 /usr/include/mysql
I am trying to get started on working with Python on Django I am by profession a PHP developer and have been told to set up django and python on my current apache and mysql setup however I am having trouble getting the Mysqldb module for python to work, I must of followed about 6 different set of instructions, I am running snow leopard and have mysql installed natively it is not part of MAMP or similar. Please can some tell me where I need to start and what steps I need to follew I would be most grateful.

On MAC OS X 10.6, Install the package as usual. The dynamic import error occurs because of wrong DYLD path. Export the path and open up a python terminal.
$ sudo python setup.py clean
$ sudo python setup.py build
$ sudo python setup.py install
$ export DYLD_LIBRARY_PATH=/usr/local/mysql/lib:$DYLD_LIBRARY_PATH
$python
import MySQLdb
Now import MySQLdb should work fine.
You may also want to manually remove the build folder, before build and install. The clean command does not do a proper task of cleaning up the build files.
I'd recomend installing macports (latest svn trunk) and installing mysql from there.
sudo port install mysql5-server
Download the MySQL-python-1.2.2 source
make sure /opt/local/lib/mysql5/bin is in your path or edit site.cfg to include:
mysql_config = /opt/local/lib/mysql5/bin/mysql_config
Comment out line 38 of _mysql.c
// #define uint unsigned int
Then run:
sudo python setup.py install
should be all good.
[Partial Answer]
You'll have more fun pulling out your teeth. MySQL/Django/Mac is a disaster. This is the farthest I've gotten:
Get MySQLDB 1.2.3
Go into that and modify setup_posix.py:
Change:
mysql_config.path = "mysql_config"
To (depending on the version number of your MySQL):
mysql_config.path = "/usr/local/mysql-5.1.34-osx10.5-x86_64/bin/mysql_config"
python setup.py build
python setup.py install
Here's a good article
First and foremost, make sure that XCode is installed. Without XCode, many pieces of the built-in Apache2 server important to developers are missing; most notably, the GNU Compiler Collection, which I would think to be requisite for MySQL bindings.
One of the key things here is to make sure you're running both MySQL and the Python adaptor in 64 bit. The default Python 2.6.1 install on Snow Leopard is 64 bit so you must install MySQL in 64 bit and build the MySQLdb adapter in 64 bit.
Make sure you have the latest Xcode installed
Install 64-bit MySQL from DMG - http://dev.mysql.com/downloads/mirror.php?id=401941#mirrors
Download MySQL-python-1.2.3 from http://download.sourceforge.net/sourceforge/mysql-python/MySQL-python-1.2.3.tar.gz
Extract and make the following edit to site.cfg:
mysql_config = /usr/local/mysql/bin/mysql_config
Then from your terminal run
ARCHFLAGS="-arch x86_64" python setup.py build
sudo python setup.py install
You should then open a Python shell and type:
import MySQLdb
If you don't get any errors you're golden.
Xcode was installed.
Follow these instructions for setting up apache/php/mysql:
http://maestric.com/doc/mac/apache_php_mysql_snow_leopard
I installed the free 32-bit version of EPD (this is optional but I wanted numpy/scipy).
Make sure you have these lines in your ~/.profile (the second line is only if you installed EPD):
export PATH=/usr/local/mysql/bin/:/usr/local/bin:/usr/local/sbin:$PATH
export PATH="/Library/Frameworks/Python.framework/Versions/Current/bin:${PATH}"
Downloaded mysqldb and run:
python setup.py build
sudo python setup.py install
Install the official release of Django or web2py. Everything worked after that. You can try the "Writing Your First Django App, Part 1" to test it out where in settings.py use:
DATABASE_ENGINE = 'mysql'
DATABASE_NAME = 'Django Polls'
DATABASE_USER = '*****'
DATABASE_PASSWORD = '*****'
DATABASE_HOST = '127.0.0.1'
DATABASE_PORT = '3306'
I also use Navicat Lite and Sequel Pro for working with MySQL.
Pydev is a nice IDE to use with Django.
Install the newest 64bit DMG version of MySQL. Remember to backup your databases if you already have MySQL installed.
enter this line in terminal:
sudo ln -s /usr/local/mysql/lib /usr/local/mysql/lib/mysql
Edit the file setup_posix in the mysql-python installation directory.
Change the line
mysql_config.path = "mysql_config"
to
mysql_config.path = "/usr/local/mysql/bin/mysql_config"
Myslq-Python needs a 64bit Version of Python. The new Python 2.7 64bit version creates an alias in /usr/local/bin/python.
Enter the following lines in the mysql-python folder
sudo /usr/local/bin/python setup.py clean
sudo ARCHFLAGS="-arch x86_64"
sudo /usr/local/bin/python setup.py build
sudo /usr/local/bin/python setup.py install
And finally try it out:
python
import MySQLdb
You could make your life a lot easier (especially on Lion) by just installing Mariadb instead:
http://mariadb.org/
It's a drop-in replacement for MySQL and is plug&play on OSX. The only thing you don't get is the MySQL system setting.
