On my Macbook, I tried running the following command with Browserify:
browserify -r ./app/main:app > static/bundle.js
But, I got the following error output:
-bash: browserify: command not found error
How do I fix that?
You need to install the Browserify NPM package globally on your machine:
npm install -g browserify
That should fix the error you're experiencing.
