Configure cache directory with an environment variable

Is your feature request related to a problem? Please describe.

In CI, my scripts run without a proper user set (no HOME), so the cache directory end up being /.cache, which triggers PermissionDenied errors. Looking at this table (which is absolutely fantastic to have, thanks), it seems that the cache directory, contrary to other settings, cannot be configured using an environment variable. Is there a reason for this? Maybe the docs simply don’t state it while it exists?

Currently the only option is to run pdm config cache_dir /my/cache/directory in each CI job.

Describe the solution you’d like

Instead of having to run the pdm config command, I’d prefer configuring this with an environment variable, once and for all jobs.

Close this since a workaround is provided. PDM_CACHE_DIR=xxx pdm install looks not so good to me. It breaks the centralized cache assumption and pdm cache commands can’t manage them correctly.

Oh, I see. Setting the HOME variable will actually allow PDM to create the $HOME/.pdm and $HOME/.cache/pdm directories without a permission error. I’ll try that, thank you @frostming 🙂
