POETRY_CACHE_DIR isn't applied during dependencies resolution

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Linux based

Issue

I try to use poetry for CI build, hence setting the POETRY_CACHE_DIR environment variable. While virtual environment is created in the right directory, a lock file try to be created in ~/.cache/.... However in CI build environment, HOME is not set so I got an error:

poetry update -vvv

Setting HOME (right were you're setting POETRY_CACHE_DIR) is not an option?

[AlexisBRENON]

Setting HOME is an option (the one used for the moment) but not a clean one; overriding HOME can have some weird effects on Jenkins... Le mer. 15 juil. 2020 22:01, Señor Rolando <notifications@github.com> a écrit :

I had the same issue with Jenkins -- setting $HOME as a hack works for now but it'd be nice if poetry fell back to the current directory if $HOME isn't available.

Hi,

I have the same problem.
When I run "poetry config list", I'm not sure the cache-dir is overidden.

poetry config --list
2022-06-03 09:30:03  cache-dir = "/home/il/jenkins/.cache/pypoetry"  # /tmp/srv_jenkins/workspace/url_feature_check_confluence_url/pypoetry

Should be resolved with #5672.
