[Python] Error in pip command - directory not installable

I am new to python and trying to setup using this-

https://github.com/facebookresearch/CodeGen/blob/main/install_env.sh

in google collab notebook.

But, it is throwing error in the below line:

pip install -v --disable-pip-version-check --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" ./


I tried changing the last parameter to /bin but still doesn't work. Can someone please help.

Below is the error:
