Im getting a error I need help with

Im getting this error zsh: command not found: mongod

and I can’t get it to go away

I have installed mongodb with the guide on the main website and help from stack over flow and I still can’t get it to work.

Switch your shell from zsh to bash

exec bash
Then try mongod command

I tried that and it didn’t work

Is mongodb/bin included in your PATH?
echo $ PATH
or cd to mongodb/bin and try to start mongod (workaround)
