Error when trying to start match: AttributeError: module 'chess.engine' has no attribute 'Opponent' #875

Closed kurt1288 closed 11 months ago

kurt1288 commented 11 months ago

Running on Windows. I've run the installation steps without any errors. The lichess-bot itself starts and doesn't show any errors upon startup. It searches for matchmaking just fine. It's when it tries to actually start the game, it runs into a problem.

Full debug output:

It looks like an old version of the python-chess dependency was installed. After activating the virtual environment (venv\Scripts\activate), try running pip install -r requirements.txt (or python3 -m pip install -r requirements.txt) again.

I think the problem was actually that I was starting the bot outside of the virtual environment. In the past I was able to do that, but it seems like that's changed? Once I started the bot inside the venv, it seems to be working fine.
