Hi, I'm experiencing an issue with

adhoc_tool

when running in CI, and I'm not sure exactly how to debug. I'm using the python package

//:root#sphinx

as my runnable. It has worked fine so far, but now I get an error that seems to relate to this. Error below:

ProcessExecutionFailure: Process 'the `adhoc_tool` at src/docs/optipyclient:gen-tool' failed with exit code 127.
stdout:

stderr:
/tmp/pants-sandbox-uCojqq/./sphinx.pex_pex_shim.sh: line 53: /tmp/pants-sandbox-uCojqq/./.cache/pex_root/venvs/22ea97ff6745f829cebb2a3ed946209934809d38/73c7d7c618fac01449fa6e57a21210c0eb8a8f21/pex: No such file or directory

I managed to inspect the sandbox and the directory

73c7d7c618fac01449fa6e57a21210c0eb8a8f21

doesn't exist. Where does this come from and what could be causing it to not exist?

Is there any symlink shenanigans happening here?

ls -a

etc. I don't think I've ever seen a

.cache

inside a sandbox.

a symlink under

.cache

inside a sandbox is a symlink to the persistent named cache

I think this is a pants caching bug that you can work around by first packing the requirement into a pex_binary and running that (will find the link in a bit, on mobile)

Thanks @broad-processor-92400, will try the work around 🙏
