I get this error if I run

npm not ok
It worked

What should I do? I tried these with no success:

chown -R cirk /usr/lib/nodejs
// and also this
chown -R cirk /usr/lib/node_modules (node_modules is empty it tries to install NPM here or what)

actually it did something, as you can see it writes at the end It worked what is a big lie!

Answer 1

Why are you running that in /usr?

If you really need to, this page suggests you may run that as root, so that would be:

curl https://www.npmjs.com/install.sh | sudo sh

But you better make sure it won't break your system, before running that.

Answer 2

I screwed up the permissions on my npm installation, and had this error when reinstalling. I solved it in the crudest way: by liberally sudo rm -rfing any directory tree that gave me trouble, then recompiling node.js and reinstalling npm.

If all else fails, you could fall back to that.
