Ive tried clearing the node cache, updating node and havent had any luck, any ideas?

Seem to fix the issue when i uninstalled node and then reinstall using homebrew. P.s really good tutorial: https://www.youtube.com/watch?v=FqMIyTH9wSg

npm config permission error

I am having permission problems with the npm config command. It seems that for some reason it is trying to change the owner of my ~/.npmrc file. When running npm config set color false, I get the following error:
npm ERR! Error: EPERM, chown '/home/bamboo/.npmrc'
npm ERR! { [Error: EPERM, chown '/home/bamboo/.npmrc'] errno: 50, code: 'EPERM', path: '/home/bamboo/.npmrc' }

The file .npmrc has the right permissions and I can edit it manually but I need to do it from the npm config command since it is part of an automated build. I can't seem to find valuable information on that matter. I set the prefix to a directory I own and can install globally without any problem but can't run configure! I am running Ubuntu 14.04.
Does anybody have some ideas?

I had the same problem.
https://github.com/npm/npm/issues/7563
Turns out changing from sudo su to sudo su - when starting the bamboo agent process solved the problem.

Got this problem once.
The .npm directory does not have sufficient permissions. Run the following command:
sudo chown -R $(whoami) ~/.npm

Yeoman Javascript error involving 'mkdir'

I'm setting up a Meanjs instance with a Yeoman generator. When I do 'sudo yo meanjs' everything works fine until it looks like it is trying to make a directory and it fails, any ideas on what is going on here?

That is a pretty common error.
Yeoman is running the following:
bower install & npm install
Bower install succeeded, however NPM install is failing because of user permissions. Just run:
sudo npm install

The ZenCoder's answer is spot on, but if you want to permanently fix this permissions error, you can follow the tutorial at: https://docs.npmjs.com/getting-started/fixing-npm-permissions
Since you're on a Mac, you could actually avoid npm permissions errors altogether by just installing node instead via homebrew:
brew install node (this will install npm too)
Homebrew installs programs to a directory that doesn't require sudo for write, so you can npm install -g <whatever> freely without it.

Needed assistance in installing http-proxy module in node.js

Yaa, so issues here was that my tmp directory did not write permission. Sorry for asking such a silly question.
