Unable to reinstall HA after Python update (venv)

Unable to get Homeassistant working in a virtual environment on MacOS

I went to upgrade my installation on Big Sur, and ran into issues. So I downgraded back to Catalina. Now I get these errors when I follow the guide at: I’ve installed Homeassistant on a Mac many times in the past and never had these issues. Can anyone help? Last login: Sat Nov 14 15:04:03 on ttys001 homeassistant@HomeAsstantMini ~ % hass --open-ui zsh: command not found: hass homeassistant@HomeAsstantMini ~ % cd homeassistant homeassistant@HomeAsstantMini homeassistan…

get the same error.

The script is apparently trying to download Pillow 7.2.0.:

2020-12-14 16:28:35 ERROR (SyncWorker_0) [homeassistant.util.package] Unable to install package pillow==7.2.0: ERROR: Command errored out with exit status 1:

However latest version is 8.0.1:

Mac-mini bin % python3 -m pip install --upgrade Pillow

Requirement already satisfied: Pillow in /Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages (8.0.1)

I used brew to install zlib:

Mac-mini bin % brew install zlib

and followed the caveat:

==> Caveats
zlib is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

For compilers to find zlib you may need to set:
  export LDFLAGS="-L/usr/local/opt/zlib/lib"
  export CPPFLAGS="-I/usr/local/opt/zlib/include"

==> Summary
🍺  /usr/local/Cellar/zlib/1.2.11: 12 files, 376.4KB

but still could not clear the error.

Thanks.
