JavaScript Error Call to 'require' failed

Hi, I am trying to reproduce your research on a ubuntu system. I am running the example.py file but I keep getting these require canvas issues. Do you have any idea on how to solve this? I have installed the dependencies through setup_js.py as well as directly installing canvas using npm, but it did not work. Thank you.

Yes, I've encountered the exact same issue on a Windows system. The error "Cannot find module 'canvas'" appears despite following the installation instructions.

python env/minecraft_server.py -H "0.0.0.0" -P 25565 -LP 5000 -U "Agent1" -W "world" -D False

try this

apt-get update
apt-get install -y build-essential libcairo2-dev libpango1.0-dev libjpeg-dev libgif-dev librsvg2-dev
npm install canvas --save

I think i was able to get the codebase running but I forgot the exact process. But for future reference, I think the problem i had was because I was using a Conda env and the npm installed its packages to some other directory so when i run the file it cannot find the dependencies.
