I am installing pythonnet using pip install pythonnet in python 3.8. I am running into this ModuleNotFoundError: No module named 'wheel' error. I did some research and I could not find a fix for this. Is there a way to fix this issue? Below is the error that I am getting.

Thanks in advance!

Either work in a virtual environment (venv), which will make sure that wheel is installed, or install it explicitly yourself, together with setuptools:

python -m pip install wheel setuptools

  • This errored out as well. with the error: ```no module named 'pycparser'``` – LearningEveryday Nov 19 '19 at 23:22
  • `python -m pip install pycparser`, but I'm rather surprised that either wheel or setuptools would depend on that. – Wim Lavrijsen Nov 19 '19 at 23:27

    It does take time for modules in python to be ready for newer versions of python and sometimes it can take up to five years if the developers are really slack – Dextron Nov 20 '19 at 01:40

Try to install all dependencies first, e.g. via pip install -r requirements.txt. Then, issue as a second command pip install pythonnet.

This solved it in my case (Centos7, Python 3.6.8, pythonnet 2.4.0)

I found this question when I got the same error in a virtual python environment. The solution was to run pip install --upgrade pip before installing my actual dependency.
