Install failure within locally built metaproject

[Neha lad]

I am trying to build a copy of a metaproject locally and install simweights within the build/lib of the same metaproject
this is the command i used
pip install --target $I3_BUILD/lib git+https://github.com/icecube/simweights.git
and i am running into following error:

Cloning https://github.com/icecube/simweights.git to /tmp/pip-req-build-7_2ebp8p
  Running command git clone --quiet https://github.com/icecube/simweights.git /tmp/pip-req-build-7_2ebp8p
  Resolved https://github.com/icecube/simweights.git to commit bb041001bc330ec14f4e627d3ae1d8b6dbbc89dd

This is not a problem with simweights but a problem with the way python was installed on cvmfs. As a work around you can do the following:

python -m pip install build
git clone https://github.com/icecube/simweights.git
python -m build
python -m pip install dist/simweights-0.1-py3-none-any.whl

I ended up doing something similar.. Thanks though

note that pip install --no-build-isolation git+https://github.com/icecube/simweights.git would have also worked
