Exception: Chained function entry cannot be changed

[Chris Kuenneth]

Hi, I am trying to use delvewheel with cibuildwheel to build windows wheels for https://github.com/kuelumbus/rdkit_platform_wheels/ . Unfortunately, I get an error (https://github.com/kuelumbus/rdkit_platform_wheels/actions/runs/1195363995)

Any idea?

I encounter the same error. Seems the latest version of pefile is throwing an error

[Chris Kuenneth]

Looks like pefile was just updated yesterday. Pinning pefile to 2021.5.24 solved it to me. pip install delvewheel pefile==2021.5.24

It looks like this was reported to pefile at erocarrera/pefile#334 and fixed in version 2021.9.3 of pefile.
