grunt Cannot find module 'coffee-script'

Question

I used the following commands to install a mean stack and create an app:

> sudo npm install -g meanio@latest // Get the mean cmdline
> mean init myApp // create your first app
> cd myApp && npm install // Install dependencies
> grunt // Launch mean

but when I get to the final grunt command I get the error:

module.js:333 throw err; ^ Error: Cannot find module 'coffee-script' at Function.Module._resolveFilename (module.js:331:15) at Function.Module._load (module.js:273:25) at Module.require (module.js:357:17) at require (module.js:373:17) at Object.<anonymous> (/home/eddie/ResFour/node_modules/grunt/lib/grunt.js:16:1)

I've tried various solutions on stackoverflow to no avail:

NodeJS - setting up mean.io cannot find module errors

Cannot find module 'coffee-script'

I also cleared npm cache and reinstalled a few times.

what happens when you run `which coffee`? what version of coffee are you running? — jcollum, May 13 '14 at 17:02
In package.json, what it said about coffee-script's version? — wilbeibi, Jul 07 '14 at 14:26

Remove node_modules directory.
npm cache clean to empty downloaded temporary dependencies, just in case.
npm install again, and better not to interrupt it while running.

These solved most of these problems for me.

You might have to run `sudo npm install` as the command could throw admin exceptions after a couple of minutes. – Tim van der Lippe May 09 '15 at 20:17
@TimvanderLippe `chmod +R $(whoami) ./npm` – wilbeibi May 10 '15 at 02:44
worked, but the "npm cache clean" part is obsolete. skip it. – olegabr Mar 23 '21 at 15:11

This worked for me:

npm install --save-dev coffee-script
node -v # v0.10.31

I had the same problem, and in the end of the log I was receiving such a message:

...

Killed

The problem was the lack of enough memory in my VM. One solution was to use swap is mentioned here.
