brew upgrade fails for Python's 2to3 conflict #2322

traversaro · 2020-12-21T13:05:03Z

Description
If I run the commands brew update and brew upgrade, the job fails. This is similar to #2248 and #1811, but the specific error is different and is probably due to some other Python being installed.

Virtual environments affected

Expected behavior
I would expect that brew upgrade works fine.

Actual behavior
brew upgrade is failing with error:

Running into the same issue in Envoy CI

Looks like it is coming from the system python?

$ which 2to3
/usr/local/bin/2to3
$ ls -la $(which 2to3)
lrwxr-xr-x  1 root  wheel  66 Dec 12 21:22 /usr/local/bin/2to3 -> ../../../Library/Frameworks/Python.framework/Versions/2.7/bin/2to3

maxim-lobanov · 2020-12-21T20:49:12Z

Most likely caused by #2217 where we switched Python 2 installation from to official pkg. This pkg brings this symlink and brew can't override it later

maxim-lobanov · 2020-12-21T20:50:28Z

@miketimofeev I guess we should leave default MacOS Python 2 without any updates (just install pip) to avoid issues with brew

miketimofeev · 2020-12-21T21:40:36Z

@maxim-lobanov there are some issues with pip installation in this case. I suggest removing the 2to3 symlink created by python2 before the python3 installation.
@traversaro as a workaround you can add rm -rf /usr/local/bin/2to3 as a first step until we've fixed it. Sorry for the inconvenience.

Thanks a lot @miketimofeev @maxim-lobanov !

CI has started failing again recently and I found this solution while going over: actions/runner-images#2322

The github mac runner images added python 3.11 but, unlike 3.10, not via brew. This causes brew install to fail with link conflict errors now that boost-python3 switched over to 3.11. Workaround this, and future python brew link errors, by ovewriting all links for python packages.

MacOS CI build started to fail in the PRs because when upgrading python it was not possible to override one existing file (related to 2to3 package). Apparently this happens because MacOS runners some times have python versions not installed/compatible with brew. Example of the failure: https://github.com/coturn/coturn/actions/runs/3850951324 The proposed workaround is taken from here: actions/runner-images#2322
