To give you a little context: I ran the following command for installing Gulp (a node package module) globally:
npm install -g gulp
The installation succeed but when I ran this
gulp command in the command line I got a
"gulp: command not found" error. It appeared that it installed “Gulp” in my local folder that is
/Users/YOURUSERNAME/node_modules and not in the global NPM folder.
You can check this by running this command:
npm root or
npm root -g, which was returning my personal directory
/Users/YOURUSERNAME/node_modules and not the expected
After some trial & error, I finally found the solution. You have to change the “npm config prefix” like so:
npm config set prefix /usr/local
Then when I re-ran
npm root -g, I got the correct root folder:
When I reinstalled Gulp globally (with the
-g param) it finally worked and appeared that it was now correctly installed in the global NPM folder. Yeay!
