I'm embarrassed to post this, but I have no experience with Python and am having issues with install. Ultimately, I am trying to connect to an Ambient Weather WS-2902C.

I am following the MacOS directions but cannot get past installing Homebrew.

If anyone can offer any guidance I would be truly appreciative. Thank you.

It seems you are tried to reinstall python 3.9. No need to do that!

However, you failed to download weewx-X.Y.Z.tar.gz. Here, X.Y.Z is the current version, i.e. 4.8.0.

curl -OL https://weewx.com/downloads/weewx-4.8.0.tar.gz

tar xvfz weewx-4.8.0.tar.gz

etc.

Thank you for the response, I really appreciate your time looking at it.

I believe expanding the source archive worked. However, when I try to change the directory I receive this message:
