I see two possible causes:
- An action you’re using is using those commands. That seems unlikely because the only action you’re using is
actions/checkout, but updating it to v2 instead of v1 may be a good idea anyway.
- Some script or other tool you’re running is issuing
I noticed the failures affect only the macos builds, and indeed the
macports-ci script you’re downloading there contains at least an
add-path command. It is also downloading and running additional tools, so those probably cause the other warnings.
You could file an issue against the source repository of that script and hope for a patch, or find another way to set up macports.
