Fix-nonhinting produces ImportError: cannot import name 'parse' from 'gflanguages'

[kosbarts]

Hi, I am trying to run fix-nonhinting on a variable font and I am getting the following error:

Any ideas what is causing it?
I am running gftools 0.9.77.dev10+gb025165 and I haven't had issues with previous versions.

Make sure you have gflanguages>=0.7.0; we added the parse function about a year ago!

How do I install it? Isn't it part of gfttools?

I ran pip install -U gflanguages and I got this:
Requirement already satisfied: gflanguages in /Users/kostas/[email protected]/Foundry5_Fonts/Peridot/venv/lib/python3.9/site-packages (0.8.9)
Requirement already satisfied: protobuf<4,>=3.7.0 in /Users/kostas/[email protected]/Foundry5_Fonts/Peridot/venv/lib/python3.9/site-packages (from gflanguages) (3.20.3)

[simoncozens]

Requirement already satisfied: gflanguages ... (0.8.9)

Ah, OK, this version was released by mistake with a bad version number and then soon yanked afterwards. Looks like you installed things at a very unlucky time. If you have gflanguages in your requirements.txt, remove it. Then delete your venv and recreate it.

[kosbarts]

I just updated the venv today! How unlucky was I?!

Thanks so much. I'll delete and recreate it.

I can't install nothing on a new venv. Getting this stupid message:
...
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
error: command '/usr/bin/clang' failed with exit code 1
[end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.

Google has lots of results for that error message. :-) Try running xcode-select --install.
