@kevinyuan have you tried passing
--eggoption to pip?yok0 commentedon Sep 10, 2018
@denfromufa the --egg option has been deprecated and is no longer valid workaround. Im trying to install 'pythonnet' on macOS myself and have been unsuccessful for hours now.
@kevinyuan solution to your issue is here:

@yok0 for mac osx please see instructions here:

I've tried the stackoverflow suggestions recommended by @yok0, namely updating wheel and setuputils, and am still getting the same error.
den-run-ai commentedon Oct 20, 2018
@gdw2 at least you should be able to build/install from extracted pythonnet directory like described in wiki. PRs are welcome to get rid of
--eggoption. I think it got somehow unintentionally added in 2016-2017.eric-appion commentedon Feb 21, 2020
I'm not convinced that this problem has actually been resolved. On Windows 10, I have just installed Python 3.8.1, then upgraded pip, setuptools, and wheel to the latest versions. The "--egg" option has been removed, so I can't use that, and when I try "pip install pythonnet" I still get "error: option --single-version-externally-managed not recognized".

updating wheel and setuputils, and am still getting the same error.
HunterTom94 commentedon Mar 28, 2020
I am using Python 3.8.2 on Win10. I am getting the same error as well.
huska6 commentedon Apr 3, 2020
same for me Python 3.8.2. 64bit, Win10, all above tested, I still have this problem.
filmor commentedon Apr 3, 2020
Python 3.8 is not yet supported.
lostmsu commentedon May 5, 2020
This happens in conda envs with 3.7 and 3.6 too.
filmor commentedon Jun 11, 2020
The problem happens in some environments because we conditionally require
pycparser(i.e. it's not usually installed withpip install pythonnetbut required whenever the DLL/SO is not one for which we provide theinterop*.csin our repo). It happened in Python 3.8 while it was unsupported and it happens in conda as they always use themvariant.I'll fix this by always requiring
pycparserin thesdist.filmor commentedon Jun 11, 2020
This particular issue on the other hand is with Quantconnect's fork of pythonnet, I won't provide any support for that.
