I'm bringing this issue across from: pypa/wheel#381
This is similar to this closed issue, except I'm using pythong 3.8.2: #46

When I pip install this library, I get the following error:

File "/private/var/folders/g8/nfhghf95hjgjgghqqb00000gn/T/pip-build-env-cs6vzugw/overlay/lib/python3.8/site-packages/wheel/bdist_wheel.py", line 328, in run
      impl_tag, abi_tag, plat_tag = self.get_tag()

  ERROR: Failed building wheel for lazy-object-proxy

I was originally getting the same issue in 5 libraries: lazy-object-proxy, pyyaml, tornado, simplejson, psycopg2) This problem has now been fixed in wheel master, and fixing my wheel version to the latest commit resolves the error in the other 4 libraries. I still get the error in lazy-object-proxy though.

Is there something specific about the way the project uses wheel that would be blocking this fix? Is there a workaround?

Versions are:

  • wheel 0.35.1 (fixed to master to use the latest fix)
  • pip 20.2.4
  • packaging 20.5
  • Python 3.8.2

I think removing the build deps from lazy-object-proxy (rm pyproject.toml should be enough I guess) would prevent the overlay being used. The overlay I believe will use the unpatched release of wheel. But this is a workaorund ofcouse - I can't commit this since pyproject.toml is there for other reasons.

Ah yeah - if I fork the library and remove pyproject.toml it works fine. Will this at least use the latest version of wheel once the fix is officially released?

Yes, I'll add a min version pin in pyproject.toml - or you can make a PR if I forget :-)

Errrr ... min version constraint, not pin.

Is this still an issue?
