Uncaught ReferenceError: angular is not defined - Mean.IO

I had the same problem and I solved in this way:

You need to install or reinstall "bower"

Check your bower.json file, it should look something like this:

{"name": "mean","version": "0.3.0","dependencies": {    "angular": "latest",    "angular-resource": "latest",    "angular-cookies": "latest",    "angular-mocks": "latest",    "angular-route": "latest",    "bootstrap": "latest",    "angular-bootstrap": "0.10.0",    "angular-ui-router": "#master"  }}

and then run the following command:

  sudo bower install --allow-root

This will install to "Angular" in the project

I had the same problem but for some reason the top answer here (reinstalling bower and running sudo bower install --allow-root) didn't work for me.

However the answer form this stackoverflow thread worked -> bower command not found Basically the author there said I wasn't setting npm prefix properly and to fix that the following was required:

$ npm config set prefix /usr/local$ npm install -g bower

note the it is bad form to install mean.io as root and as a result run bower or npm as root.We actually built processes into mean-clithat will disallow running as root.Running as root is the sure way to expose mean to more serious security issues and to "contaminating" you .npm and .bower caches with a mix of normal and root based permissions which is very frustrating for "newbies"
