Following along with Free Code Camp’s Node course, I was playing with how-to-npm from Node School, I followed the first exercise and ran how-no-npm verify. My npm version was out of date and following the prompt, I ran npm install npm -g. That seemed to complet successfully, however, running how-to-npm verify subsequently gave me a lovely string of errors, the top one being
Error: Cannot find module 'process-nextick-args’
Running any npm command seemed to result in something similar.
To fix this, I did the following - first upgrade Node itself with nvm:
Step 1 - upgrade node itself with nvm:
nvm install v8.9.3
Step 2 - install how-to-npm again:
npm install how-to-npm -g`
Step 3 - upgrade npm
npm i -g npm
Now I can run how-to-npm verify again and everything works
