Mac OS doesn't like Streamlit?


Struggling to install Streamlit on Mac OS (which I am new to).

Steps followed:

  1. Python 2.7 came pre-installed. I manually installed 3.10
  2. Followed installation steps as per Installation - Streamlit Docs

Debug info

  • Streamlit version: (1.25.0)
  • Python version: (3.10)
  • OS version: Mac OS High Sierra 10.13.6
  • Browser version: Brave Version 1.56.11 Chromium: 115.0.5790.102 (Official Build) (x86_64)

Error information

Streamlit installation seems to be running fine until it encounters pyarrow. The error message onwards is below:

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

Thanks in advance.


Hi there @Shawn_Pereira ,

Looking at the error message it seems cmake is not found. Try installing Homebrew (a popular package manager for macOS), if you don’t have it already, and then :

brew install cmake

If this doesn’t work, try using conda to create a specific environment (not the base environment), install the Python runtime + libraries you wish to use. Hope this helps!

Thanks @marduk for the prompt response. Apparently, homebrew is not available for the OS version I am using. Since, I have already pulled out enough hair using this Macbook, I think I will just partition the disk and install windows on Mac :slight_smile:
