Font metrics don't look right in FontForge; Unable to build in dev branch

[allenrsty]

The metrics on the font file built on GitHub look good with glyph names like uniNNNN.

But it doesn't look right with a master branch local build. The glyph names are the actual characters.

So I tried to build the dev branch. Then I got this error:
ModuleNotFoundError: No module named 'pkg_resources'

Which I tried to fix by installing an older version of setuptools:
pipenv install "setuptools<82"

{
"key": "setuptools",
"package_name": "setuptools",
"installed_version": "81.0.0",
"required_version": "81.0.0",
"dependencies": []
}

But I'm still getting this error:
ModuleNotFoundError: No module named 'pkg_resources'

I built the font in master with ttfautohint 1.6, Python 3.7.9 and old versions of the libraries.

pip list

Package           Version

MutatorMath       2.1.1
pip               24.0
pyclipper         1.1.0.post1
setuptools        68.0.0
ufo2ft            2.4.0
ufoLib            2.3.2
wheel             0.42.0

But it still has the same problem with the metrics. I'm not a Python developer so I may not have done everything right.

Is there a way to fix the font with a fonttools script? Or with a setting in FontForge?
