self-hosted tools cache setup not working automatically on Linux & Mac with v2

Hi, I am getting Version 2.x with arch x64 not found error message from my self-hosted runner on ubuntu 18.04. However, I can see that version 2.7.18 is in the versions-manifest.json file.

Run actions/setup-python@v2

Version 2.x is available for downloading

So getting this to work automatically on Mac and Linux is going to require some extra steps. I’m working on updating the README with a easy(ish) guide on how to do this after I figure out the last step to this puzzle.

There are a couple of things going on here.

• The AGENT_TOOLSDIRECTORY env variable needs to be set to /opt/hostedtoolcache (on Linux at least, different on Mac). We compile Python in this directory with --enable-shared so it is non-portable and it has to always be located in the same place (see here). If the path is different you’ll get an error like error while loading shared libraries: libpython3.7m.so.1.0 when reaching the end of setup.sh
• Because we’re in the /opt/hostedtoolcache directory, you need to be running as sudo to modify this. However, if you’re tried starting the runner with sudo, you’ll get an error that says Must not run interactively with sudo. To get around this, you have to configure passwordless sudo which is what our hosted runners do
• Even with both set, there needs to either be some modifications done to the setup.sh file that is downloaded so that all that necessary commands like mkdir run with sudo or so that setup-python does all the necessary magic behind the scenes (what i’m trying to get working)

This looks like the local tools cache setup isn’t working for the first time when running on linux?

The download appears to be fine, however, the setup script must be running into some issues. Investigating… (most likely an env variable isn’t set or something)

---

Edit: If you set an env variable called AGENT_TOOLSDIRECTORY with something such as export AGENT_TOOLSDIRECTORY=~ it will almost successfully set everything up. Still figuring out why it doesn’t work…

If the value is set to ~, it would create a directory ~/Python and everything would be copied over and setup in there.
