setup-python: Cannot create directory ‘/opt/hostedtoolcache’ after recent release

@k24dizzle - Alternatively, you can use the context variable.

        env:
          AGENT_TOOLSDIRECTORY: ${{ runner.tool_cache }}
        uses: actions/setup-python@v4
        with:
          python-version: "3.11.0-beta.4"

We where having this issue while setting up our own runners with the ubuntu example in: https://github.com/philips-labs/terraform-aws-github-runner. We could fix it by making these changes to the ubuntu example: https://github.com/philips-labs/terraform-aws-github-runner/pull/2302/files

Fair enough, I guess I am probably looking at this trough the this would be better for my use case lens without seeing the bigger picture.

env: AGENT_TOOLSDIRECTORY: /home/actions/actions-runner/_work/_tool/

Hi, I am working on the same repo as @kenorb where we are using the setup-python GH action.

I ended up following the suggestion from @techman83:

       env:
          AGENT_TOOLSDIRECTORY: ${{ runner.tool_cache }}
        uses: actions/setup-python@v4
        with:
          python-version: "3.11.0-beta.4"

This really makes me wonder why AGENT_TOOLSDIRECTORY doesn’t default to the value of RUNNER_TOOL_CACHE if not set/defined instead of defaulting to /opt/hostedtoolcache.

Cf this comment from @techman83 :

Internally they use a TOOLCACHE_ROOT variable, which they set to RUNNER_TOOL_CACHE when AGENT_TOOLSDIRECTORY is not provided. If the same is implemented here, actions-python will behave in the same manner, and respect the path that is configured as part of the self hosted runner options.

That would make a lot more sense to me and by doing so we wouldn’t have to tinker with AGENT_TOOLSDIRECTORY when calling the action.

@dsame I don’t, I hope I have articulated clearly enough to show that this is a regression for self hosted users. Even though that regression technically aligns the behaviour of actions/setup-python with the documentation, I don’t think that is the best technical outcome here.

@k24dizzle just set AGENT_TOOLSDIRECTORY to any location the runner user has write permission to.

Namely for Pytjon-3.11.0-betat.4 as in the log above:

  env:
    AGENT_TOOLSDIRECTORY: /home/actions/actions-runner/_work/_tool/Python/3.11.0-beta.4/x64/
