Gulp no longer working after upgrading to node.js 4.1

Question

I just upgraded from node 0.12.x to 4.1.0. After doing so gulp no longer works. Here is what I'm seeing in the console after I try to run gulp

module.js:338
throw err;
^

Error: Cannot find module '/Users/me/.node/lib/node_modules/gulp/node_modules/v8flags/cache/4.5.103.35.flags.json'

I've tried running npm install, and updating to the latest version of gulp but that didn't fix the problem. Any ideas on how to fix this?

Answer 1

You can fix it by deleting the "npm" and "npm-cache" folders in "/usr/local/".

Then do a

 "npm install -g npm"

Followed by:

"npm install -g gulp"

Everything should now be updated and ready to rock!

EDIT: On Windows the folders can be found in "/users/(username)/AppData/Roaming"

Answer 2

Delete the Gulp module in the error, so in your case delete this folder

/Users/me/.node/lib/node_modules/gulp

Then clean your npm cache:

$ npm cache clean

And finally install Gulp globally again:

$ npm install -g gulp

Then you should find it works again - I did!
