Error installing Steroids.js on Mac through Terminal

Question

I've been looking at Steroids as an alternative to PhoneGap for performance reasons. I've tried installing it through Terminal, but I don't really know what I'm doing. :)

I've gone through the documentation, but when I run this: steroids create TestApp, I get this error: steroids: command not found.

Also, after installing Node.js and running this line: npm install steroids -g, it outputs lines like this:

npm http GET https://registry.npmjs.org/steroids
npm http 304 https://registry.npmjs.org/steroids

etc. At the end, I get this:

npm ERR! fetch failed https://registry.npmjs.org/graceful-fs/-/graceful-fs-1.1.14.tgz
npm ERR! fetch failed https://registry.npmjs.org/minimatch/-/minimatch-0.2.9.tgz
npm ERR! 
npm ERR! Additional logging details can be found in:
npm ERR!     /Users/MyUser/npm-debug.log
npm ERR! not ok code 0

I have no idea what is going on here, so if you need more details, please let me know. :) Is there something I'm doing wrong? Thanks!

EDIT: I also get this error while the script is being run: npm ERR! registry error parsing json

Answer 1

It's because the NPM registry is currently (as of 11/4/2013 5:44PM eastern time) down. You can check the status on their status page.

Answer 2

Try to install with sudo

sudo npm install steroids -g
