Pythonnet: Failed building wheel

Created on 23 Oct 2017 · 11Comments · Source: pythonnet/pythonnet

Environment

Pythonnet version: 2.3.0
Python version: 2.7.10
Operating System: macOS Sierra 10.12.6

Details

I'm trying to install pythonnet on my mac. I have pretty much the same issue as #269, I even tried the solutions suggested there but they didn't work.
I ran the Pypi installation command in my terminal

pip install pythonnet

This is the output for the command:
```Collecting pythonnet

You probably need to install from master branch:

What helped was another hint that we found in the thread @dmitriyse already mentioned: using --egg:

$ pip install --egg git+https://github.com/pythonnet/pythonnet
DEPRECATION: --egg has been deprecated and will be removed in the future. This flag is mutually exclusive with large parts of pip, and actually using it invalidates pip's ability to manage the installation process.

pip install pip --upgrade

Should solve this issue

This completely broke my setup:

ImportError: cannot import name main

@phxn please read this thread below and this has nothing to do with pythonnet. But in general I agree that users should work in virtual environment, rather than messing with system python installation:

https://github.com/pypa/pip/issues/5599

denfromufa on 13 Nov 2018

Another way to resolve this is to download Windows SDK 10 (latest version). If this alone doesn't work then download Visual Studio 2019 (again whichever is the latest version). This updates the wheel process.

harshikanu on 28 Dec 2019

Try downloading the wheel file from https://pypi.org/project/pythonnet/#modal-close pythonnet downloads. Make sure you download the correct version and use pip install . cp in the file name will give you the python version number it's compatible with.

Should solve this issue

I wanted to install a venv for python3.8.2 and Building wheel for pandocfilters and others prdouced erros. Executing your steps and building the venv again solved my issue.
