Bug report

  • ran brew update and can still reproduce the problem?
  • ran brew doctor, fixed all issues and can still reproduce the problem?
  • ran brew gist-logs <formula> (where <formula> is the name of the formula that failed) and included the output link?
    (Kept saying "Error: Not Found" when I ran brew gist-logs 'python@3.9' or just brew gist-logs python)
  • if brew gist-logs didn't work: ran brew config and brew doctor and included their output with your issue?

Build: pkg-config ✘
Required: gdbm ✔, openssl@1.1 ✔, readline ✔, sqlite ✔, xz ✔
==> Caveats
Python has been installed as
  /usr/local/bin/python3

Unversioned symlinks `python`, `python-config`, `pip` etc. pointing to
`python3`, `python3-config`, `pip3` etc., respectively, have been installed into
  /usr/local/opt/python@3.9/libexec/bin

You can install Python packages with
  pip3 install <package>
They will install into the site-package directory
  /usr/local/lib/python3.9/site-packages

What you were trying to do (and why)

I did pip3 install --user zstandard, because I like zstandard.

What happened (include command output)

What you expected to happen

I expected zstandard to be installed

Step-by-step reproduction instructions (by running brew install commands)

  1. brew install python
  2. pip3 install --user zstandard

Other notes

This is similar to this patch. I think that that issue got resolved with an early patch (cd26ccbb) to at least get Python installable again.
However, the patch for upstream python has a reviewer comment pointing out the bug I'm running into, and the patch has changed since (6511bf5).
I'm guessing that this ticket I'm reporting right now (so that other confused users will see what's going on) will be resolved when the python formula is updated again (either to an improved upstream, or to include a newer patch)
