Mysterious error from Pip

[willrogers]

[Note: I have a similar setup to #486, with a somewhat complex and non-standard build.]

In my GitHub Action, I get the following log, which I do not understand:

Building wheel...
  
      + rm -rf /tmp/cibuildwheel/built_wheel
      + mkdir -p /tmp/cibuildwheel/built_wheel
      + pip wheel /project -w /tmp/cibuildwheel/built_wheel --no-deps
  ERROR: No .egg-info directory found in /tmp/pip-pip-egg-info-focvdlqs
  Processing /project

I previously had this Travis config to build wheels, but I can no longer run it:

https://github.com/atcollab/at/blob/7a42dc1c498f9d78c671ac5fc2a1e6487ef462dc/.travis.yml

Although the build mechanism is somewhat convoluted the error seems unrelated. It may be in Pip or Setuptools but I cannot reproduce it elsewhere.

Do you have a pointer at the log? There was a bad release of setuptools (51.3.0) that could cause this, it was fixed about an hour later, though, so you'd have to have gotten really lucky if that was the problem.

Can you see it? https://github.com/willrogers/at/runs/1729259986?check_suite_focus=true

51.3.3 this time, but I have been trying to upgrade setuptools and pip and have seen this on multiple Python versions too.

Some more logging:

Maybe try setting CIBW_BUILD_VERBOSITY to 1 or 2? That should give some more indication of what's happening.

Thank you, that was enough for me to figure out the problem, which is on my side. Hopefully I can fix it now.
