I installed oemer using the instructions from this page: https://github.com/BreezeWhite/oemer .

pip3 install oemer

(I had to use pip3 on my system.)

Then went to run it, also according to instructions on that page:

oemer ~/Pictures/trumpet.jpg
bash: oemer: command not found

So I get “command not found”.

I thought maybe I needed to add the path to my $PATH, so I ran

pip3 show oemer
Name: oemer
Version: 0.1.5

and added /Library/Frameworks/Python.framework/Versions/3.12/lib/python3.12/site-packages to my $PATH. Still didn’t work. So I explicitly ran:

/Library/Frameworks/Python.framework/Versions/3.12/lib/python3.12/site-packages/oemer ~/Pictures/trumpet.jpg
bash: /Library/Frameworks/Python.framework/Versions/3.12/lib/python3.12/site-packages/oemer: is a directory

Ahh, oemer is a directory, not an executable.

So my question is, how do I run oemer, or any other package installed by pip for that matter?

I tried:

pip3 /Library/Frameworks/Python.framework/Versions/3.12/lib/python3.12/site-packages/oemer
ERROR: unknown command "/Library/Frameworks/Python.framework/Versions/3.12/lib/python3.12/site-packages/oemer"

…and…

python3 /Library/Frameworks/Python.framework/Versions/3.12/lib/python3.12/site-packages/oemer
/usr/local/bin/python3: can't find '__main__' module in '/Library/Frameworks/Python.framework/Versions/3.12/lib/python3.12/site-packages/oemer'

Searches such as “how to run pip packages on macos” come up empty, with most results showing how to install pip on macos.
