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

Can you please post the full traceback of pip install pyarrow? Can you also specify your operating system and version of python? – Circlet

You can also try pip install --upgrade pip setuptools wheel and then retry pip install streamlit. – Circlet

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

Answer 2

I also faced this same issue and I noted that pyarrow is a requirement in streamlit version 0.63.0. So you can use pip install streamlit==0.62.0 and it will work just fine

While it's true that using a version of Streamlit < 0.63 will work, you'll miss out on every update from now on. For most people, they are accidentally using 32-bit Python instead of 64-bit, as https://mcmap.net/q/623941/-error-installing-streamlit-it-says-quot-error-could-not-build-wheels-for-pyarrow-which-use-pep-517-and-cannot-be-installed-directly-quot indicates – Bougainville

Answer 3

Streamlit Version 0.62.1 and python version 3.8.5 works fine.
