Poetry env seems not working well with gym(0.21.0).

The problem occured when trying 'poetry install'.

` - Installing gym (0.21.0): Failed

ChefBuildError

Backend subprocess exited when trying to invoke get_requires_for_build_wheel

error in gym setup command: 'extras_require' must be a dictionary whose values are strings or lists of strings containing valid project/version requirement specifiers.

Note: This error originates from the build backend, and is likely not a problem with poetry but with gym (0.21.0) not supporting PEP 517 builds. You can verify this by running 'pip wheel --no-cache-dir --use-pep517 "gym (==0.21.0)"'.`

I searched about it and it seems to be a problem with gym(0.21.0). I have no idea how to tackle with this problem using given poetry.lock.

Is it another way to avoid this problem? Also, would it be convenient if we could upgrade to gym(>=0.22)?

Many Thanks.

After hours of searching I finally hit the truth that it's almost IMPOSSIBLE to install stable-baseline through poetry.

See python-poetry/poetry#4511

It's really annoying that such a elegant repo can't be installed with poetry. I really hope that we can somehow get rid of it, like, using another version of gym maybe?

Thx.
