Environment
- pip version: latest
- Python version: 3.5.4
- OS: Windows
This happens when using nuget to get Python, and only on Python 3.5. Python 2.7 and 3.6-3.8 are just fine. I have only seen this problem on Windows. This is breaking cibuildwheel
, which uses this setup. See pypa/cibuildwheel#358 - there you can see the logs. This may be true with any portable install, I'm not sure.
Description
The surrounding environment is used when making a PEP 518 build, rather than the new one created for the build. When building with -v
, it is making the environment, but it is not being used.
