Problem installing nes-py in WSL ubuntu using conda-CodePudding

I was trying to install nes-py in WSL using pip install nes-py, but I got the following error (I am pasting the entire terminal message).

I have tried many fixes, such as cloning the nes-py repo and installing it by running python setup.py install in its directory, changing the MANIFEST.in file, and some others, but nothing worked. If somebody can help in any way, that would be amazing!

Thanks in advance!

P.S. I am new to using both Conda and WSL/Ubuntu, so any help in that regard is appreciated as well. I used to just use cmd integrated with VS Code.

Found the solution. Took a while, but it was a simple one. I just had to install g by running sudo apt install g in the terminal. After that, the nes-py installation worked like a charm.
