• 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: Fedora 32

• Poetry version: 1.0.10

• Link of a Gist with the contents of your pyproject.toml file: Link

• I've also done poetry config virtualenvs.path .venv

Issue

Apparently, poetry invalidates virtual environment even if literally nothing happened to it. Here is an example where I install a package and and try to list packages, but it says that environment is broken and installs it again: Gist. My only idea is that PyCharm, which is configured to use the venv, messes something up but it shouldn't write anything in venv, I guess.
