Problem pip installing

[finegan-dollak]

I struggled somewhat to install on a Mac with an M1 using the direct install method from https://docs.minedojo.org/sections/getting_started/install.html. This post includes the steps I tried and a workaround that eventually succeeded but is rather awkward; a more straightforward solution could make installation easier for others.

After following the instructions to set up JAVA_HOME and create the conda environment, I attempted pip install minedojo, which failed with the following error:

I switched to following the instructions to install the latest main branch:

git clone https://github.com/MineDojo/MineDojo && cd MineDojo
pip install -e .

and encountered the same problem.

After some digging, I found that the issue arises from using gym==0.21 (see details here). Using the fix documented there allowed me to install gym==0.21, but it also caused new errors with pip install -e because it prevented installation of lxml.

I tried a clean conda environment, replaced gym==0.21 with gym in requirements.txt. This was enough to successfully run pip install -e ., but using a newer version of gym causes an assertion error when I tried to run validate_install.py, so I had to move back to gym 0.21. To do this, I ran

pip install setuptools==65.5.0 pip==21
pip install gym==0.21

which worked because I had already installed all the other packages. I can now run validate_install.py successfully. I'm not sure if a user would be able to make pip install minedojo work directly.

My system info: macOS Ventura 13.4 on Apple M1 Pro Python 3.9.16

note: your pip and pip3 may be different instances. I substituted

pip install setuptools==65.5.0 pip==21
pip install gym==0.21

with

pip3 install setuptools==65.5.0 pip==21
pip3 install gym==0.21

and that worked for me

I got rid of the gym==0.21 to just gym

[fangyuan-ksgk]

it works for me

pip install setuptools==65.5.0 pip==21 pip install gym==0.21 pip install minedojo

BTW, this only allows the pip install minedojo to come through, but import minedojo still gives error, which is fixed by changing file: /minedojo/tasks/init.py, line 29 according to https://docs.python.org/3/library/importlib.resources.html#importlib.resources.path

importlib_resources.as_file(importlib_resources.files("minedojo.tasks.description_files").joinpath(fname))

cannot find a 'tasks' folder in minedojo , but i did find init.py and there were a lot of them
