pip install fails due to pep 517

[Harald Schilly]

Hi, I had trouble running pip3 install nle on Ubuntu 22.04.

below, notice it says pyproject.toml, not setup.py. My guess is, this is due to those new-ish build isolations.

What did help (workaround 👍 ) is pip3 install --no-use-pep517 nle

Maybe you have to look into https://github.com/tttapa/py-build-cmake/ ?

This fixes Colab as well. You have to install with -v to see the cmake error, but it's the same

!sudo apt-get install -y build-essential autoconf libtool pkg-config \
    python3-dev python3-pip python3-numpy git flex bison libbz2-dev
! pip install --no-use-pep517 nle

Any ideas how to fix this longer term? Would like to have a stable way to include NetHack in a bunch of containers from the pip package, without rebuilding from source
