Can't update Serverless on Mac Catalina

I’m trying to update Serverless on mac catalina to 1.78.1. When I run serverless init I get the following error:

Serverless command “init” not found. Did you mean “info”? Run “serverless help” for a list of all available commands.

I tried several times to reinstall serverless but still run into the same issue. Here’s my environment information:
