virtualenv and python path - python

i did a virtualenv in c:\users\devtool.virtualenv\devenv
After i run activate.bat.
And last i wrote a simple py file to test environment:
import os,sys
for x in sys.path:
print x
print os.executable
and result is weird
C:\Users\devtool\.virtualenv\devenv\Scripts
C:\Python27\lib\site-packages\setuptools-0.6c11-py2.7.egg
C:\Python27\lib\site-packages\virtualenv-1.8.4-py2.7.egg
C:\Python27\lib\site-packages\pip-1.2.1-py2.7.egg
C:\Users\developer\.virtualenv\devenv\Lib\site-packages\django
C:\Windows\system32\python27.zip
C:\Python27\DLLs
C:\Python27\lib
C:\Python27\lib\plat-win
C:\Python27\lib\lib-tk
C:\Python27
C:\Python27\lib\site-packages
['C:\\Users\\developer\\.virtualenv\\devenv\\Lib\\site-packages\\django']
C:\Python27\python.exe
in fact it is just using base python install.
What is the point of using virtualenv?
i am getting errors with django, installed in virtualenv.
i can solve it, just need to rewrite django-admin.py to append to search path my virtualenv folder, but still what is need of virtualenv in this case.
another thing that i cant understand. In the python search path, there is a line
C:\Users\devtools\.virtualenv\devenv\Lib\site-packages\django
and when i use django-admin.py i get
Traceback (most recent call last):
File "C:\Users\devtools\.virtualenv\devenv\Scripts\django-admin.py", line 12, in module>
from django.core import management
ImportError: No module named django.core
but django folder is in the path

I have also faced the same issue few days before. From the base folder, you have to execute the following command.
C:\Users\devtools\.virtualenv\devenv> python Scripts\django-admin.py startproject myproj

virtualenv extends/overrides your system python environment with its paths prepended to the paths of the system python installation. You see, you .virtualenv site-packages are listed before the system site-packages, that's how it works.
The thing you have to keep in mind that activate patches your current command line environment, so you must run activate before running python code depending on your virtualenv.

ModuleNotFoundError: No module named 'asyncio.streams'

i am working on a long project in Django and suddenly i faced this error:
import asyncio
File "C:\Users\AppData\Local\Programs\Python\Python38\lib\asyncio\__init__.py", line 17, in <module>
from .streams import *
ModuleNotFoundError: No module named 'asyncio.streams'
I tried to instal it using : pip install asyncio, But again it gave some errors :
Traceback (most recent call last):
File "c:\users\appdata\local\programs\python\python38\lib\shutil.py", line 587, in _rmtree_unsafe
with os.scandir(path) as scandir_it:
FileNotFoundError: [WinError 3] The system cannot find the path specified: 'C:\\Users\\AppData\\Local\\Temp\\pip-req-tracker-ua43f6rj'
please Tell me how can i fix it . I am Using Python 3.8.1
Please reinstall python3.8.1 for windows 10
Packages and modules in python can be imported when they appear in the PYTHONPATH environement variable or in the sys.path list.
On each PYTHONPATH expanding, will ends up in the sys.path list.
so make sure that, the instalation of your asyncio was successeful and its path exist in the sys.path list. how you check? see below:
in comand line or in script.py type:
import sys
p_asyn=r'C:\Users\AppData\Local\Programs\Python\Python38\lib\asyncio'
if p_asyn not in sys.path:
print('asyncio not in the sys path list! :-(')
sys.path.append(p_asyn)
its better to append new paths to the PYTHONPATH rather than editing the sys.path.
Anywa, if the module you are trying to import (asuncio) is a built in lib/module you should check if the pyhton installation was successful and the path environement variable edited correctly and has all paths that should be.
in windows make sure that python installation dir appears in the path. if not use the set command,
set PYTHONPATH=%PYTHONPATH%;C:\My_python_lib
Python usually stores its library (and thereby your site-packages folder) in the installation directory. So, if you had installed Python to C:\Python\, the default library would reside in C:\Python\Lib\ and third-party modules should be stored in C:\Python\Lib\site-packages.
This attended to windows users.

Error with TensorFlow MNIST [duplicate]

Since updating from Homebrew Python 2.7.11 (from 2.7.10) I'm suddenly unable to test register my package on PyPi from the PyCharm IDE console.
Running (as an "External Tool")
python -B setup.py register -r pypitest
I now get
Traceback (most recent call last):

Process finished with exit code 1
I'm not sure how to proceed. I only get this issue if I execute from within my IDE's console. If I do it directly at the system command line (Terminal on OS X) I have no problems.
OS X 10.11.3; Homebrew Python 2.7.11; PyCharm 5.0.3
tl;dr: Fix this issue by doing one of the following:
type hash -r python, OR
log out and log in.
EDIT: An answer to my related question makes it clear what's happening here. When you install a new version of python, you may need to run hash -r python to tell bash to reset the "cached" location to the python executable.
In my case, I was typing python, which was on my $PATH at /usr/local/bin/python. But bash was still using the old cache location /usr/bin/python. So, the old executable was called, but the new path was provided to python in sys.argv[0]. This means that the old executable was running, but the new sys.executable value caused all the wrong modules to get loaded (including the io module).
I'm having the same problem. I installed python 2.7.11 via an installer from Python.org. Strangely, the issue seems to be related to some subtle difference between how OSX launches python when I invoke it from the shell using the full path vs. using just the word python.
So, for me, this works (invoking python via the full path /usr/local/bin/python):
$ which python
/usr/local/bin/python
$ /usr/local/bin/python -c "import io"
$
... but this doesn't:
$ python -c "import io"
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/io.py", line 51, in <module>

So, as a workaround, you can try doing the same thing.
Elsewhere, I've posted a separate question about this puzzling behavior. Maybe somehow merely calling python invokes some strange mix of the 2.7.11 executable with the 2.7.10 dylibs??
According to https://github.com/klen/python-mode/issues/634:
I had the same issue, but successfully fixed. In my case I compiled
python and vim with homebrew, when PYTHON_PATH has been specified and
set to one of my dev environments, where I also had some libraries,
including io. Workaround was simple: open new terminal, make sure that
you do not have custom PYTHON_PATH, uninstall python, uninstall vim.
Reinstall both of them.
and
Problem solved.
Culprit is the update from python 2.7.10 to 2.7.11.
If you are using conda package control, simply run "conda install
python=2.7.10" will solve this problem.
This doesn't give the root cause though. Since this happens with _io, this looks like a bug in python 2.7.11 (unlikely, there would be a world-scale outcry and a prompt fix if it was) or some packaging bug or version mismatch specifically with the homebrew version (and maybe some related ones, too).
Try to import _io in the console and if it succeeds, check if it was loaded from the same path.
Reinstall python.
brew unlink python && brew reinstall python
Secure the path
export PYTHONPATH=$PYTHONPATH:/usr/local/bin/
BACKUP and Change the order of "paths" file.
sudo nano /etc/paths
it seems, the order of paths, it is decisive to run python properly. In my case, the result was:
#sudo nano /etc/paths
/usr/bin
/usr/local/bin
/bin
/usr/sbin
/sbin
On my mac, path is like this.
$ which python
/usr/local/bin/python
Now I can run both:
$ /usr/local/bin/python -c "import io"
$ python -c "import io"
I had the same issue, it is successfully fixed by just replacing the _io.so file.
sudo find / -name _io.so
copy the path of the _io.so file which DOES NOT belong to python-2.7.11. For example, copy the path of _io.so which is under python-2.7.5:
/usr/local/Cellar/python/2.7.5/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/_io.so
Replace the /usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/_io.so file with the _io.so that you just found.
This happened to me as well in MacVim. I solved it by making sure :python print(sys.path) is using system Python (e.g. /Library/Python/2.7/...)
Since I installed MacVim via Homebrew, I just did that by:
Spawn a new shell that had which python -> /usr/bin/python. For my case I needed to remove the pyenv line from my .bash_profile. If you installed Python via Homebrew you may want to brew unlink python first
brew reinstall macvim
If your problem is caused by anaconda, it is unnecessary to remove //anaconda directory.
Just open your ~/.bash_profile, find the line
export PATH="//anaconda/bin:$PATH
and comment it out, then restart your terminal session.
Another quick workaround if you don't mind sticking with Python 2.7.10 is to specify the path of the Python interpreter executable that will be used for the virtualenv. On OSX that path is usually /usr/bin/python:
virtualenv venv --python=/usr/bin/python
Can't add comment (?) so this just to share my exp., downgrade to 2.7.10 works fr me.
I got this error after a failed NLTK download, I needed to uninstall anaconda:
sudo rm -rf ~/anaconda
update PATH variable
This happened when I already had tried to create a venv in a folder, and mistakenly was trying to initialize a second one! So I just removed venv directory and re-ran the command. Very likely this is not the answer to this solution, but searching my error brought me here, so it may help some others who are stuck.
I solved this issue by removing the symbolic link that was in /usr/local/bin and copying the actual python binary, that was pointed to by said link, there.
I had the same issue when I tried to use PyCharm. Solved by setting "python interpreter" in project configuration to point to the python virtual env I wanted to use, which was an Anaconda env. Somehow the interpreter path was missing the "anaconda" portion of ~/.../anaconda/.../_io.so. No need to uninstall anaconda.

pdfminer - ImportError: No module named pdfminer.pdfdocument

I am trying to install pdfMiner to work with CollectiveAccess. My host (pair.com) has given me the following information to help in this quest:
When compiling, it will likely be necessary to instruct the
installation to use your account space above, and not try to install
into the operating system directories. Typically, using "--
home=/usr/home/username/pdfminer" at the end of the install command
should allow for that.
I followed this instruction when trying to install.
The result was:
running install
running build
running build_py
running build_scripts
running install_lib
running install_scripts
changing mode of /usr/home/username/pdfminer/bin/latin2ascii.py to 755
changing mode of /usr/home/username/pdfminer/bin/pdf2txt.py to 755

Removing /usr/home/username/pdfminer/lib/python/pdfminer-20140328.egg-info
Writing /usr/home/username/pdfminer/lib/python/pdfminer-20140328.egg-info
I don't see anything wrong with that (I'm very new to python), but when I try to run the sample command $ pdf2txt.py samples/simple1.pdf I get this error:
Traceback (most recent call last): File "pdf2txt.py", line 3, in <module>
from pdfminer.pdfdocument import PDFDocument ImportError: No module named pdfminer.pdfdocument
I'm running python 2.7.3. I can't install from root (shared hosting). The most recent version of pdfminer, which is 2014/03/28.
I've seen some posts on similar issues ("no module named. . . " but nothing exactly the same. The proposed solutions either don't help (such as installing with sudo - not an option; specifying the path for python (which doesn't seem to be the issue), etc.).
Or is this a question for my host? (i.e., something amiss or different about their setup)
I had an error like this:
No module named 'pdfminer.pdfinterp'; 'pdfminer' is not a package
My problem was that I had named my script pdfminer.py which for the reasons that I don't know, Python took it for the original pdfminer package files and tried to compiled it.
I renamed my script to something else, deleted all the *.pyc file and __pycache__ directory and my problem was solved.
use this command worked for me and removed the error
pip install pdfminer.six
Since the package pdfminer is installed to a non-standard/non-default location, Python won't be be able to find it. In order to use it, you will need to add it to your 'pythonpath'. Three ways:
At run time, put this in your script pdf2txt.py:
import sys
# if there are no conflicting packages in the default Python Libs =>
sys.path.append("/usr/home/username/pdfminer")
or
import sys
# to always use your package lib before the system's =>
sys.path.insert(1, "/usr/home/username/pdfminer")
Note: The install path specified with --home is used as the Lib for all packages which you might want to install, not just this one. You should delete that folder and re-install with --
home=/usr/home/username/myPyLibs (or any generic name) so that when you install other packages with that install path, you would only need the one path to add to your local Lib to be able to import them:
import sys
sys.path.insert(1, "/usr/home/username/myPyLibs")
Add it to PYTHONPATH before executing your script:
export PYTHONPATH="${PYTHONPATH}:/usr/home/username/myPyLibs"
And then put that in your ~/.bashrc file (/usr/home/username/.bashrc) or .profile as applicable. This may not work for programs which are not executed from the console.
Create a VirtualEnv and install the packages you need to that.
I have a virtual environment and I had to activate it before I did a pip3 install to have the venv see it.
source ~/venv/bin/activate

changing virtualenv folder on windows

after a computer fix my python projects dir (windows) changed (say from d: to f:).
now all my virtualenvs are broken. after activating the env the project inside the virtualenv can't find the dependencies and the custom scripts (from the env\scripts folder)won't work
tried running:
virtualenv --relocateble ENV_NAME (with the env name ..)
like in this stackoverflow question and it outputted a lot of lines like:
Script agent\Scripts\deactivate.bat cannot be made relative
and my virtualenv is still broken.
when I manually changed activate.bat set VIRTUAL_ENV to the new path. some scripts work again. but the relocate scripts still doesn't run and most of the scripts are still broken
even running the python interpeter fails with:

is there any way to fix this? HELP
Update: I also changed manually the shebang python interpeter line in all scripts in ENV\Scripts. now all fail with the same python failure as above

since I can't run python from the virtualenv, I can't print the python path from there
Correcting python directory path in ENV_FOLDER\Lib\orig-prefix.txt helped me
Seems like your system and local environments create a mix of libraries and binaries from different versions of python.
Chances are you would need to delete Lib, Scripts and Include and start again with virtualenv .. You might be able to save the site-packages folder, but if you have requirements.txt files, you should probably reinstall packages instead (see also: How do I install from a local cache with pip? ).
Anyway, I believe you can create a script that does all this in one step.
I installed both py2 and py3 on my windows 10. And got this error by create virtualenv by using virtualenv xxx directly. After purging folder xxx and reinstalling with virtualenv -p TARGET_PY_EXE xxx everything works smoothly.
Hope this will help multiple python windows users.
By the way, I simply create env variables as PY2 and PY3 instead of adding absolute paths into PATH.

django import error - No module named core.management

Ok, I see plenty of these errors around. I have tried everything I know to do and have yet to figure this out.
I am working on a development server running python 2.5 and Django 1.3. Django 1.3 was installed using python setup.py install after unpacking the tar.gz download.
All works well, I seldom have the need to run manage.py but am trying to use the new staticfiles app and am running into problems.
python manage.py collectstatic
Traceback (most recent call last):
File "manage.py", line 2, in <module>
from django.core.management import execute_manager
ImportError: No module named core.management
Ok, so I have PATH issue.
From Django install I double check my site-packages directory.
python -c "from distutils.sysconfig import get_python_lib; print get_python_lib()"
/usr/lib/python2.5/site-packages
Ok, let's check out what I have, echo $PYTHON_PATH was empty, so I set it
export PYTHON_PATH=/usr/lib/python2.5/site-packages/django
Still no luck. Lets check what sys.path has to say
>>> import sys
>>> print sys.path
['', '/usr/lib/python2.5', '/usr/lib/python2.5/plat-linux2', '/usr/lib/python2.5/lib-tk', '/usr/lib/python2.5/lib-dynload', '/usr/local/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages/PIL', '/usr/lib/python2.5/site-packages/django', '/var/lib/python-support/python2.5']
path is there, I even created /usr/lib/python2.5/site-packages/django.pth with contents
cat /usr/lib/python2.5/site-packages/django.pth
/usr/lib/python2.5/site-packages/django/
Anyone got an clues to what is going on here?
I found a symlink further up the path that was getting in the way, but no on to a new error.

I also tried creating a new project to see if there were any issues there and get the same utils.version error.
Side node: Unode from #django helped me a bit, set up virtualenv on same machine and got past the errors so still not sure what is up with this actual install here, but it seems to not be in the django projects but in the django/python install.
If, like me, you are running your django in a virtualenv, and getting this error, look at your manage.py.
The first line should define the python executable used to run the script.
This should be the path to your virtualenv's python, but it is something wrong like /usr/bin/python, which is not the same path and will use the global python environment (and packages will be missing).
Just change the path into the path to the python executable in your virtualenv.
You can also replace your shebang line with #!/usr/bin/env python. This should use the proper python environment and interpreter provided that you activate your virtualenv first (I assume you know how to do this).
If you are in a virtualenv you need to activate it before you can run ./manage.py 'command'
source path/to/your/virtualenv/bin/activate
if you config workon in .bash_profile or .bashrc
workon yourvirtualenvname
*please dont edit your manage.py file maybe works by isnt the correct way and could give you future errors
I had the same problem because I was installing Django as a super user, thus not in my virtualenv. You should not do sudo pip install Django
Instead, install it this way:
$ source ./bin/activate
$ pip install Django
Please, reinstall django with pip:
sudo pip install --upgrade django==1.3
(Replace 1.3 to your django version)
As known this was a path issue.
the base of my custom packages shared a name with a directory set in a /etc/profile. The packages were in a different location however for the webserver. So I removed the offending entries from my $PYTHONPATH and was good to go!
Thanks for the help.
Another possible reason for this problem is that your OS runs python3 by default.
Either you have to explicitly do: python2 manage.py
or you need to edit the shebang of manage.py, like so:
#!/usr/bin/env python2
or if you are using python3:
#!/usr/bin/env python3
You are probably using virtualenvwrapper. Don't forget to select your enviroment by running:
$ workon env_name
I had this error while trying to run an embedded system (using django of course) on a Raspberry Pi 2 (and not a VM)
Running this:
sudo pip install Django
Made the trick!
just in case a fellow using Raspbian/Jessie gets this
python3 manage.py runserver
Check version of Python
For me, my server was using Python 2.4. I simply looked up Python 2.7, which was installed on my server, and created an alias.
alias python=python2.7
If you need to know more, I found the solution here
I was getting the same problem while I trying to create a new app. If you write python manage.py startapp myapp, then it looks for usr/bin/python. But you need this "python" which is located in /bin directory of your virtual env path. I solved this by mentioning the virtualenv's python path just like this:
<env path>/bin/python manage.py startapp myapp
Solved it!!!
After searching for ages and trying all these other suggestions which didn't work, I finally found the solution for my setup.
My setup/scenario:
Windows, Python27
My django project is checked out via svn
when running python manage.py runserver in the new folder, I got the import error
python manage.py runserver used to work in the original folder (which I would commit changes from) until I deleted it
Solution
Remove any the folder named django in the same directory of manage.py
Thats right...as soon as I removed the folder "django" which only contained a __init__.py file...I could run the server again!
Have no idea why though
Try change your first line of manage.py.
Change
#!/usr/bin/python
by
#!/usr/bin/env python
For those of you using Django 1.6 or newer, note that execute_manager was removed. There is a solution posted in the second SO answer here.
Store the python python path in a variable and execute.This would include the otherwise missing packages.
python_path= `which python`
$python_path manage.py runserver
==================================SOLUTION=========================================
First goto: virtualenv
by running the command:
source bin/activate
and install django because you are getting the error related to 'import django':
pip install django
Then run:
python manage.py runserver
(Note: please change 'runserver' to the program name you want to run)
For the same issue, it worked in my case.

Good luck!!
environment: Python 3.9.6, Django 3.2.6, VS Code
Just disable Pylance extension and reload your VS Code.
I had a similar problem. PyCharm couldn't run the server but I could run it from the command line. I tried which python and then made sure that PyCharm was same interpreter and then everything worked OK.
This error usually occurs when django is not installed.
If you have already installed django but still getting the same error, then you must be working in separate virtual environment. You need to install django in your virtual environmnent as well. When you are in shell of virtual machine simply do this:
pip install django
It is because virtual machine has separate file system, it doesn't recognize django even if it is installed on your system.
I fixed this problem by changing #PATH="$VIRTUAL_ENV/bin:$PATH" to PATH="$PATH:$VIRTUAL_ENV/bin"
For reasons not obvious to me the python executable in the virtualenv dir does not see django but the normally installed python does.
Just a single mistake
This happened with me as well. My mistake was that I've created Django project before creating virtual env, later activated the env and was trying to start the server. Just install Django after activating env it will work
your project is created using an old version of django-admin.py, older than django1.3
to fix this create another django project and copy its manage.py and paste it in the old one
Agreed completely that this is a path issue but fwiw, I had this same error. It was due to the mistake of using a relative path for my Python executable when setting up my virtual environment. I had done this:
virtualenv -p ~/python_runtimes/2.7.3/bin/python venv2.7.3 --distribute
Instead I had to give the full path to the Python executable.
HTH,
Harlin
source ~/blog-venv/bin/activate
pick your virtualenv to replace "blog-venv" here.
Be sure you're running the right instance of Python with the right directories on the path. In my case, this error resulted from running the python executable by accident - I had actually installed Django under the python2.7 framework & libraries. The same could happen as a result of virtualenv as well.
Okay so it goes like this:
You have created a virtual environment and django module belongs to that environment only.Since virtualenv isolates itself from everything else,hence you are seeing this.
go through this for further assistance:
http://www.swegler.com/becky/blog/2011/08/27/python-django-mysql-on-windows-7-part-i-getting-started/
1.You can switch to the directory where your virtual environment is stored and then run the django module.
2.Alternatively you can install django globally to your python->site-packages by either running pip or easy_install
Command using pip: pip install django
then do this:
import django
print (django.get_version()) (depending on which version of python you use.This for python 3+ series)
and then you can run this:
python manage.py runserver
and check on your web browser by typing :localhost:8000
and you should see django powered page.
Hope this helps.
I included the name of the new App to the INSTALLED_APPS list in the settings.py "before" I issued the startapp command. Once I removed the list entry, I could create the app.
I solved this problem by using 'django-admin' command as following instead:
django-admin startproject _project_name
just remove the ".py" attached to "django-admin"
Having an application called site can reproduce this issue either.
I got this due to forgetting that I installed Django using pip -U, so it was only available to the user running my Django app. To run manage.py I had to do
sudo su -s /bin/bash MY_DJANGO_USER
/PATH/TO/MY/APP/manage.py
