Problem Description

GitPod instance errors out when running poetry install

Checklist

• [] I have installed dependencies via poetry install (see CleanRL's installation guideline.
• [X] I have checked that there is no similar issue in the repo.
• [X] I have checked the documentation site and found not relevant information in GitHub issues.

Current Behavior

After starting the GitPod instance from the README.md file, I attempt to run poetry install. I receive the following:

**RuntimeError

The Poetry configuration is invalid:

• Additional properties are not allowed ('group' was unexpected)**

Expected Behavior

Poetry installs the requirements without an error message.

Possible Solution

Ensure the correct version of poetry is specified/installed out of the box in the GitPod environment.

A workaround: pip3 uninstall poetry pip3 install poetry -U

Steps to Reproduce

1. Click on the GitPod button on REAME.md.
2. Click through the steps to start the environment. Now, you wait for the environment to start.
3. Log into a terminal.
4. Ensure you are in the cleanrl directory. If not, cd to it.
5. Enter poetry install in the terminal.
6. Error message received.

It’s probably cached incorrectly. Would you mind creating a PR that updates the Dockerfile.gitpod and modify the poetry installation line to pip install poetry --upgrade?
