Installing Libraries for Python 3.6.0

[vfong1982]

Hi,

 

I am struggling trying to get a Python library called Pymunk 5.3.2 installed on a Python 3.6.0 installation using pip. I have tried using pip install pymunk-5.3.2-py2.py3-none-win_amd64.whl and it's constantly coming up with:

 

Fatal Error in Launcher: Unable to create process using '"'

 

I have tried a repair installation to no avail - this is driving me crazy! (even tried copying the WHL file to the same directory as the scripts directory)

It's normally one of two things, either you have a space in the path where you're trying to run it from, or you haven't upgraded pip if on an older version

No spaces in the path, I tried installing it from the same scripts directory. I cannot seem to work out how to upgrade pip either - every command I run involving pip just returns the same error, regardless of what switches I add to it. It feels like something is fundamentally broken.

[Steve21]

The pip path error would be linked to where pip is installed, so like a space in program files etc, rather than the module. So putting the module in the pip path won't help if there's still a space etc.

 

What's the full path to where you've installed it?

C:\Python36-32\

[Steve21]

That part should be fine then, and if you try to update pip?

 

python -m pip install -U pip

Requirement already up-to-date: pip in c:\python36-32\lib\site-packages

No difference, PIP still won't do anything useful

[Steve21]

If the python command works fine it's deffo a problem in the setup You got something silly like two versions of python installed?

 

If you just want the one package installed for now you should be able to do it like this

 

python -m pip install pymunk-5.3.2-py2.py3-none-win_amd64.whl

 

What's your environment variables set as for python/pip?

 

Steve

[vfong1982]

There are no references to the Python installation directory in PATH environmental variable. I added it, and managed to install the library... phew!

Ideally I need to run a batch file to fix the path variable on several computers, any idea what the command line would be?

[Steve21]

Do you mean manually run, or GPO wise? Can do it both ways

 

Steve

[vfong1982]

Just a simple batch file - I'm actually intending to run it as a program on SCCM

Using pygame as an example, we call:

 

pip install \\server\share\python\pythonversion\modules\pygame-1.9.3-cp36-cp36m-win_amd64.whl --no-cache-dir

 

And based installed / installable on the presence of python (dependency) and whether

C:\Program Files\python36\lib\site-packages\pygame-1.9.3.dist-info\description.rst

exists or not.
