node.js - NPM cannot install dependencies - Attempt to unlock something which hasn't been locked

Question

I've been trying to run an npm install on my package.json file, but I'm having a lot of trouble. It keeps saying "Error: Attempt to unlock XXX, which hasn't been locked" on all my dependences. Here's one of them:

Error: Attempt to unlock tbd@~0.6.4, which hasn't been locked
        at unlock (/usr/local/lib/node_modules/npm/lib/cache.js:1304:11)
        at cb (/usr/local/lib/node_modules/npm/lib/cache.js:646:5)
        at /usr/local/lib/node_modules/npm/lib/cache.js:655:20

        at Object.oncomplete (fs.js:107:15)

If I try to run it as sudo, it seems to get further and start installing some packages, but some new errors popup instead:

I recently updated my node and npm installations. So maybe that has something to do with it. Also, most of my development has been at the office and today I'm working over VPN, so maybe that has something to do with it too.

Any ideas?

As per photusenigma at: https://github.com/npm/npm/issues/4815

Run these commands in a terminal window (note - DON'T replace the $USER part...thats a linux command to get your user!):

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

...and...if you're on a mac (like I am), and still see errors after running these commands, then run this last one and you should be good. (Recommend you try testing before you do this one. I don't like changing the permissions on the ENTIRE /usr/local directory unless it really seems necessary!)

sudo chown -R $USER /usr/local
