Error Installing streamlit It says "ERROR: Could not build wheels for pyarrow which use PEP 517 and cannot be installed directly"

Question

When I try pip install streamlit it fails with the error message:

ERROR: "Could not build wheels for pyarrow which use PEP 517 and cannot be installed directly"

I tried installing pip install pyarrow directly but still gives the same error message

Answer 1

In my case the problem was related to Python version. More specifically I noticed in error logs:
RuntimeError: Not supported on 32-bit Windows

So then I installed Python 3.8.6 (x64 version) instead of x32

and the problem was solved with

pip install pyarrow
