Cannot import easysnmp: ImportError: libnetsnmp.so.30

I'm trying to use easysnmp in a virtual environment, but get an error when I import it:

Output:

Any idea why, and how to fix it?

is /usr/local/lib/ in PATH ?

echo $PATH

$ echo $PATH
/fastapi/sv/venv/bin:/usr/local/openssl/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/snorton/bin:/home/Tools

Looks like it's not. How do I fix this?

I should note that this script will be run by multiple users, including as a cron job, so I can't just add it to my .bash_profile

This seems to have fixed it... it that all that was needed or is this something that will always need to be run?

Output:
sudo ldconfig /usr/local/lib

It could be the variable LD_LIBRARY_PATH
