Fix NPM Error: Attempt To Unlock * Which Hasn't Been Locked

Posted by Weston Ganger on January 21, 2016

I was getting the weird error Attempt to unlock some_module, which hasn’t been locked.

That’s weird, turns out its a permissions thing.

sudo chown -R $USER ~/.npm
sudo chown -R $USER /usr/local/lib/node_modules

# if your on a OSX and still having problems
sudo chown -R $USER /usr/local
