2 years ago Hi @rwarren thank you for reporting this.
I had a quick look on your reproducer and I think I will leave this issue for the other maintainers since I don't have any familiarity with this part of the code, but I would like to ask, if it is possible to update your reproducer to do a import setuptools as the first thing before importing any distutils? (Just to make sure all the setuptools patches are applied before anyone starts to investigate...)

OS
Win10
Additional environment information
I have tried to make this work on Win10 with various combinations of:
With the latest VS2019 build tools, I'm installing these components (as directed by the compiler wiki):
Description
Main problem: Basic MS builds do not currently work at all on Win10 with currently available VS2019 Build Tools!
The fastest way to see/reproduce this is to try and initialize a
distutils.msvccompiler.MSVCCompilerwith any clean Win10 environment combination and the a VS2019 C++ Build Tools install (with any variety of combinations, as as indicated in the env section).Specifically, this code throws a
DistutilsPlatformErrorexception because it can't find Microsoft Visual C++ 14.2:The specific exception thrown, with message, is:
This error seems like it is due to the following things:
C:\Program Files (x86)\Microsoft Visual Studio 14.2\VC\Tools\MSVCC:\Program Files (x86)\Microsoft Visual Studio\2019\BuildToolsMSVC 142 - VS 2019 C++ x64/x86build tools are installed, it does not install them to the version-dotted dir schema that setuptools is expectingWhen installing build tools today (with the MSVC142 tools selected), the proper location for executables like
cl.exeis in dirs like this:There are no older MSVC build tools installers available to get a 14.2-based install dir. The URL I am trying to downlad build tools from is https://visualstudio.microsoft.com/vs/older-downloads/, as given by the compiler wiki.
Further details:
Stepping through the
setuptools.msvcimplementation, the following things can be seen:setuptoolsdoes pick up the VS 2019 build tools dir as follows (inSystemInfo.known_vs_paths):{16.11: 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\BuildTools'}2019dir in the path)setuptoolsis looking for is 14.2C:\Program Files (x86)\Microsoft Visual Studio 14.2For search purposes, I ran into this problem when trying to build WxPython with a simple
pip install wxpython.Expected behavior
setuptools should work with the currently available VS2019 build tools from Microsoft.
Alternatively, the compiler wiki (or other docs?) should be corrected to point to whatever location has compatible build tools.
How to Reproduce
As described in the description. Essentially:
pip install setuptools -Uto get the latest (just in case)Output
