[Bug Report] `ValueError: option names {'--envfile'} already added`

[DEKHTIARJonathan]

I believe the new feature introduced in #199 is not functional.

All my CI jobs that uses pytest-env==1.5.0 are now failing with the same error:

I'm clearly not the one registering --envfile so I suppose an interaction between pytest-env and pytest-dotenv (a new dependency).

Once fixed - I recommend yanking 1.5.0 as it's a breaking chance and not functional.

Thanks a lot for the work.

They are not meant to be installed at the same time, note that pytest-dotenv is now no longer maintained. You can use just pytest-env now and drop pytest-dotenv.

EDIT: misread

[The-Compiler]

python-dotenv and pytest-dotenv are not the same thing...
