Incorrect error message when a specific Python version requires a downlevel pip #643
Description
Activity
Apparently there is a dependency on
python-versionswhere older versions of Python need to be rebuilt. Meanwhile, or in any case, there are environment variables that should be used in the setup script.Hello @dirkf. Thank you for your report. We'll investigate the issue.
Hello @dirkf. Sorry for the late response. I've checked build and previous reply. I think it will be better to set up environment variables on the job level because it comes from the pip directly. Besides, possibly some users will need this messages.
For now I'm going to close the issue.
Description:
actions/setup-pythonlogs an error, as shown below, on installing a specific Python version that is not supported by the latest pip. For example, Python 3.5.x requires pip < 21. Since the version of Python was specified and the correct pip was ensured, the older pip version is expected and not an error.Even if a newer pip were available, this should be an informational or warning message.
See also #233.
Action version:
v4 and earlier
Platform: (probably irrelevant)

This output is generated:
[error]You are using pip version 20.3.4, however version 23.0.1 is available.Python 3.5.x is not supported by pip > 20.3.4, so this is correct behaviour and not an
