Hi Benjamin,

thanks a stack for working on this! The GitHub Action recipe conceived by @sondrelg on behalf of @snok actually looks like it is well prepared for being able to help us on getting the caching for Poetry environments on Windows right [1]. Kudos to @sondrelg and good luck to you!

With kind regards,
Andreas.

Just a remark: virtualenv-path is not set within the canonical example for Windows at https://github.com/snok/install-poetry#windows.
