can't import libraries installed in python - python

I usually try to install libraries for python by :
sudo apt-get install python-lib name
and when the operation is complete I can't import the library I have tried this for pygame,tk and other libs. I also usually can't install any library with pip because it gives me a bunch of error and I have also tried installing packages with their source by :
python setup.py build
python setup.py install
and usually I get errors on the "build" part.
What should I do?

Are you using Ubuntu? Probably yes. Ubuntu have two versions of python preinstalled: python2.7 and python3.4. Your command is installing library for python2.7. If you are writing your script for python 3.4, then you fail with import libraries. Try using sudo apt-get install python3-packagename to install library for python3.
edit:
are you using your pip command with sudo? sudo pip instal ...?

Need to install Python Pint Package using MSYS

I am very new to using MSYS and I need it to run a Fortran based code through python interface. I followed the whole installation procedure in this link
https://github.com/SINTEF/thermopack/blob/main/addon/pycThermopack/README.md
and when I tried to install Python Pint package I kept getting this error:
MSYS Error
It seems that this package is very important to run the GUI correctly. What did I miss here? Is there any other way to install this package?
Thanks a lot in advance.
Solution
I managed to install it by installing Pip command using
$ pacman -S python3-pip
$ pip3 install --upgrade pip
pip install Pint

Keep getting the "Command "python setup.py egg_info" failed with error code 1" [duplicate]

I'm trying to install some packages with pip.
But pip install unroll gives me
Command "python setup.py egg_info" failed with error code 1 in
C:\Users\MARKAN~1\AppData\Local\Temp\pip-build-wa7uco0k\unroll\
How can I solve this?
About the error code
According to the Python documentation:
This module makes available standard errno system symbols. The value of each symbol is the corresponding integer value. The names and descriptions are borrowed from linux/include/errno.h, which should be pretty all-inclusive.
Error code 1 is defined in errno.h and means Operation not permitted.
About your error
Your setuptools do not appear to be installed. Just follow the Installation Instructions from the PyPI website.
If it's already installed, try
pip install --upgrade setuptools
If it's already up to date, check that the module ez_setup is not missing. If it is, then
pip install ez_setup
Then try again
pip install unroll
If it's still not working, maybe pip didn't install/upgrade setup_tools properly so you might want to try
easy_install -U setuptools
And again
pip install unroll
Here's a little guide explaining a little bit how I usually install new packages on Python + Windows. It seems you're using Windows paths, so this answer will stick to that particular SO:
I never use a system-wide Python installation. I only use virtualenvs, and usually I try to have the latest version of 2.x & 3.x.
My first attempt is always doing pip install package_i_want in some of my Visual Studio command prompts. What Visual Studio command prompt? Well, ideally the Visual Studio which matches the one which was used to build Python. For instance, let's say your Python installation says Python 2.7.11 (v2.7.11:6d1b6a68f775, Dec 5 2015, 20:40:30) [MSC v.1500 64 bit (AMD64)] on win32. The version of Visual Studio used to compile Python can be found here, so v1500 means I'd be using vs2008 x64 command prompt
If the previous step failed for some reason I just try using easy_install package_i_want
If the previous step failed for some reason I go to gohlke website and I check whether my package is available over there. If it's so, I'm lucky, I just download it into my virtualenv and then I just go to that location using a command prompt and I do pip install package_i_want.whl
If the previous step didn't succeed I'll just try to build the wheel myself and once it's generated I'll try to install it with pip install package_i_want.whl
Now, if we focus in your specific problem, where you're having a hard time installing the unroll package. It seems the fastest way to install it is doing something like this:
git clone https://github.com/Zulko/unroll
cd unroll && python setup.py bdist_wheel
Copy the generated unroll-0.1.0-py2-none-any.whl file from the created dist folder into your virtualenv.
pip install unroll-0.1.0-py2-none-any.whl
That way it will install without any problems. To check it really works, just login into the Python installation and try import unroll, it shouldn't complain.
One last note: This method works almost 99% of the time, and sometimes you'll find some pip packages which are specific to Unix or Mac OS X, in that case, when that happens I'm afraid the best way to get a Windows version is either posting some issues to the main developers or having some fun by yourself porting to Windows (typically a few hours if you're not lucky) :)
It was resolved after upgrading pip:
python -m pip install --upgrade pip
pip install "package-name"
I got stuck exactly with the same error with psycopg2. It looks like I skipped a few steps while installing Python and related packages.
sudo apt-get install python-dev libpq-dev
Go to your virtual env
pip install psycopg2
(In your case you need to replace psycopg2 with the package you have an issue with.)
It worked seamlessly.
I got this same error while installing mitmproxy using pip3. The below command fixed this:
pip3 install --upgrade setuptools
Download and install the Microsoft Visual C++ Compiler for Python 2.7 from https://www.microsoft.com/en-in/download/details.aspx?id=44266 - this package contains the compiler and set of system headers necessary for producing binary wheels for Python 2.7 packages.
Open a command prompt in elevated mode (run as administrator)
Firstly do pip install ez_setup
Then do pip install unroll (It will start installing numpy, music21, decorator, imageio, tqdm, moviepy, unroll) # Please be patient for music21 installation
Python 2.7.11 64 bit used
Other way:
sudo apt-get install python-psycopg2 python-mysqldb
I had the same issue when installing the "Twisted" library and solved it by running the following command on Ubuntu 16.04 (Xenial Xerus):
sudo apt-get install python-setuptools python-dev build-essential
It's a dependency issue.
I tried running the following commands helped me sorting out the dependencies, in my case the dependency was
grpcio
pip3 install --upgrade pip
python3 -m pip install --upgrade setuptools
pip3 install --no-cache-dir --force-reinstall -Iv grpcio==1.36.1
pip3 install pulsar-client==2.7.0
remember you must have python3 installed in your system.
First try:
pip install unroll
For sure not work :)
Then Try:
pip2 install unroll
Still get error Try:
pip3 install unroll
If pip3 Worked then suggest to change configuration to use pip3 as pip because you will get a lot of issues as the modern now is Python3 = pip3 if you execute a script files.
I had the same problem.
The problem was:
pyparsing 2.2 was already installed and my requirements.txt was trying to install pyparsing 2.0.1 which throw this error
Context: I was using virtualenv, and it seems the 2.2 came from my global OS Python site-packages, but even with --no-site-packages flag (now by default in last virtualenv) the 2.2 was still present. Surely because I installed Python from their website and it added Python libraries to my $PATH.
Maybe a pip install --ignore-installed would have worked.
Solution: as I needed to move forwards, I just removed the pyparsing==2.0.1 from my requirements.txt.
I ran into the same error code when trying to install a Python module with pip.
#Hackndo noted that the documentation indicate a security issue.
Based on that answer, my problem was solved by running the pip install command with sudo prefixed:
sudo pip install python-mpd2
For me this worked
python3 -m pip3 install -U pip
you can also try
python -m pip install -U pip
pip3 install --upgrade setuptools
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with -m pip instead of running pip directly.
Use python3 -m pip "command", eg:
python3 -m pip install --user pyqt5
I tried all of the above with no success. I then updated my Python version from 2.7.10 to 2.7.13, and it resolved the problems that I was experiencing.
That means some packages in pip are old or not correctly installed.
Try checking version and then upgrading pip.Use auto remove if that works.
If the pip command shows an error all the time for any command or it freezes, etc.
The best solution is to uninstall it or remove it completely.
Install a fresh pip and then update and upgrade your system.
I have given a solution to installing pip fresh here - python: can't open file get-pip.py error 2] no such file or directory
next installation helps me:
pip3 install cython
This worked for me:
sudo xcodebuild -license
Upgrading Python to version 3 fixed my problem. Nothing else did.
I downloaded the .whl file from http://www.lfd.uci.edu/~gohlke/pythonlibs/ and then did:
pip install scipy-0.19.1-cp27-cp27m-win32.whl
Note that the version you need to use (win32/win_amd-64) depends on the version of Python and not that of Windows.
I had this problem using virtualenvs (with pipenv) on my new development setup.
I could only solve it by upgrading the psycopg2 version from 2.6.2 to 2.7.3.
More information is at https://github.com/psycopg/psycopg2/issues/594
I faced the same problem with the same error message but on Ubuntu 16.04 LTS (Xenial Xerus) instead:
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-w71uo1rg/poster/
I tested all the solutions provided above and none of them worked for me. I read the full TraceBack and found out I had to create the virtual environment with Python version 2.7 instead (the default one uses Python 3.5 instead):
virtualenv --python=/usr/bin/python2.7 my_venv
Once I activated it, I run pip install unirest successfully.
try on linux:
sudo apt install python-pip python-bluez libbluetooth-dev libboost-python-dev libboost-thread-dev libglib2.0-dev bluez bluez-hcidump
Had the same problem on my Win10 PC with different packages and tried everything mentioned so far.
Finally solved it by disabling Comodo Auto-Containment.
Since nobody has mentioned it yet, I hope it helps someone.
I had the same problem and was able to fix by doing the following.
Windows Python needs Visual C++ libraries installed via the SDK to build code, such as via setuptools.extension.Extension or numpy.distutils.core.Extension. For example, building f2py modules in Windows with Python requires Visual C++ SDK as installed above. On Linux and Mac, the C++ libraries are installed with the compiler.
https://www.scivision.co/python-windows-visual-c++-14-required/
Following below command worked for me
[root#sandbox ~]# pip install google-api-python-client==1.6.4
Methods to solve setup.pu egg_info issue when updating setuptools or not other methods doesnot works.
If CONDA version of the library is available to install use conda instead of pip.
Clone the library repo and then try installation by pip install -e . or by python setup.py install
upgrading python's version did the work for me.
I have just encountered the same problem when trying to pip install -e . a new repo. I did not notice that the contents of setup.py haven't been saved properly and I was effectively running the command with an empty setup.py.
Hence you may experience the same error message if the setup.py of the target package is either empty or malformed.
I solved it on Centos 7 by using:
sudo yum install libcurl-devel

ImportError: No module named 'ldap' Python 3.5

I'm running Python 3.5 (on Windows) and I have installed python-ldap from https://pypi.python.org/pypi/python-ldap/
I also tried using ldap3 but I keep getting an error saying
"ImportError: No module named 'ldap'
I looked around and saw some people saying there's no python-ldap for 3.5 so I installed 2.6 still getting the same error.
Is there a way to import ldap and make it work for Python 3.5?
Try the command below:
sudo apt-get install libsasl2-dev python-dev libldap2-dev libssl-dev
sudo pip3 install pyldap
Open a command line(cmd, powershell, git bash)
Check you python version
$ pyhton --version
Go to https://www.lfd.uci.edu/~gohlke/pythonlibs/
Download the library according with your python version and windows system
And install it on a command line using
pip install file_downloaded.whl
For example:
If you have python 3.5x and windows x64,
download the file python_ldap‑3.2.0‑cp35‑cp35m‑win_amd64.whl
pip install python_ldap‑3.2.0‑cp35‑cp35m‑win_amd64.whl
I'm running Apache Airflow on an Amazon EC2-Instance and I was getting "ImportError: No module named 'ldap3'. I used these two sites https://www.python-ldap.org/en/latest/installing.html and http://ldap3.readthedocs.io/installation.html to run the commands sudo python -m pip install python-ldap and sudo pip install ldap3 but my pip wasn't working for the last command so after some investigation I found out in my /usr/bin/ directory I had pip, pip-2.7, pip-3.6, and pip-python so I changed the command to pip-3.6 install ldap3 and then everything worked! Hope this helps someone.
I tried multiple approaches but finally, PyPI official documentation fixed this.
I was trying to execute on VS Code and did pip3 install python-ldap, but it didn't solve the issue. So I did the below from VS Code
# %% - This runs the below code as a Jupyter notebook cell
!pip3 install python-ldap
Now, I am able to import ldap and use it
Inside you folder, you can use virtualenv for python 3, example:
/opt/python-ldap-test
virtualenv -p /usr/bin/python3.5 venv
source venv/bin/activate
and then
pip install ldap3
It's extremely complicated to make things from 2.X to work in 3.X. Have you tried using it in a separate, 2.X only script and using it from there? It's not so unusual to combine python 2.X with 3.X in that manner or so I've heard.

Python 2.7: No module named setup tools

I am trying to clone and install the keras package from github. When I run sudo python setup.py install, it says no module named setuptools. I looked at some posts that were for python 3; however, this solutions did not work for me. I am working on a terminal from a windows computer. I am using python 2.7. I tried the following commands: python -m pip install -U pip setuptools from this website: https://packaging.python.org/installing/. However, nothing seemed to work.
If you are working on Windows then you should be typing batch commands, not bash (Linux, OSX), therefore, sudo ... should not be used by you.
Firstly, I would recommend to install pip, it will make package update and installation a lot easier. Save it as get-pip.py and run the following in the directory the file is located python get-pip.py. Official pip website.
Then install upgrade pip which will also install the latest versions of setuptools and wheel with this python -m pip install -U pip setuptools.

Installing requests-kerberos on Windows

Is there any way to install requests-kerberos on Windows?
When I try to install it with pip I have the following error:
py -m pip install requests-kerberos
ImportError: No module named 'commands'
Command "python setup.py egg_info" failed with error code 1 in C:\Users\user1\AppData\Local\Temp\pip-build-n8s_inn\kerberos
I would be grateful if anyone knew another kerberos module. I'm using Python 3.4 and Windows 8.
Best regards.
The commands module was deprecated in python 2.6.
Thus, the issue appears to be a problem with your pip installation, and not with requests-kerberos.
There are a few things you can try, but I would focus on ensuring pip is working correctly. While you could install the package manually, you are really just pushing the pip problem down the road until the next time you install a package.
Ensure pip is installed correctly.
Use the pip command to ensure you are running pip in the python 3.4 context: (Note, this is my output, yours will be different because you are on Windows and running 3.4)
$ pip --version
pip 1.5.6 from /Library/Python/2.7/site-packages/pip-1.5.6-py2.7.egg (python 2.7)
Additional information about pip can be found here.
Download and install manually
Download the package manually from the pypi repo.
Download the .tar.gz
Extract the tar.gz and run python setup.py install
