Uncaught ReferenceError: angular is not defined -

问题:

I have followed the steps to install mean.io, but when I browse the localhost:3000 I get a blank page and when I open the console I get a list of files pointing to the same error:

Uncaught ReferenceError: angular is not defined

my issue is something similar to this, but I re-installed bower and it didn't work I'm still getting the error.

I'm trying to install this in ubuntu 14.04

this is the screen I get:

Do I need to perform some sort of modification to any script, file reference or configuration, any suggestions?

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"

If you are behind the proxy, then still problem not solved. So in order to solve it you need to include proxy-setting in .bowerrc file as

 {
  "directory": "public/lib",
  "proxy":"http://user:passwd@server:port",
  "https-proxy":"http://user:passwd@server:port"

}

Now run

sudo npm install -g bower
sudo bower install --allow-root
