Why does PIP installation of haystack RAG pipeline lead to metadata generation failure?

Question

I have been trying to install the RAG pipeline from deepset haystack to create my own Generative Question Answering pipeline, but everytime I try and install the package, I run into a subprocess error and metadata generation failure

I tried running earlier versions of the Pipline to see if that would fix the issue and check that the libearies I had was up to date along with the pip-tools, ez-setup and wheel The same result occured.

Package    Version
---------- -------
colorama   0.4.6
ez-setup   0.9
iniconfig  2.0.0
packaging  23.2
pip        23.3
pluggy     1.3.0
pytest     7.4.2
setuptools 68.2.2
wheel      0.41.2

The Error output:

python setup.py egg_info did not run successfully.

  note: This error originates from a subprocess, and is likely not a problem with pip.
