Yeoman, Angular Generator, and Karma Test not working

Question

I'm trying to use Yeoman with the angular-generator to start a new application. I run this command (according to the docs) to start a new app: `yo angular my-app-name` All dependencies have been download and if I run `grunt serve` my base app shows up in browser and everything look to work fine. The problem starts when I try to run: `grunt test` I get an error : `Warning: Task "karma" not found. Use --force to continue.` So I've added these line: ``` "grunt-karma": "*", "generator-karma": "*" ``` in my `packeage.json` file, remove the `node_modules` folder and runned ``npm install`. I was hping to solving the issue but now i get the error: ``` loading "grunt-karma.js" tasks...ERROR >> Error: Cannot find module 'socket.io-client' Warning: Task "karma" not found. Use --force to continue. Aborted due to warnings. ``` I've tried to google a bit but I can't find anything about. I'm running MacOsX 10.8.5 and node v0.10.0 . Any suggestion? Thanks in advance

Accepted Answer

There have been problems with Karma and angular-generator. Are you running the latest version of the generator?

Not sure what caused the failure, but sometimes there are issues installing karma dependencies. Try running:

```
npm install grunt-karma karma-ng-html2js-preprocessor karma-ng-scenario --save-dev 
```

And if that doesn't work then workaround you can use for now is to add the following dependencies to your package.json after it failed installing:

```
"karma-ng-scenario": "~0.1.0",
"grunt-karma": "~0.6.2",
"karma-script-launcher": "~0.1.0",
"karma-chrome-launcher": "~0.1.2",
"karma-firefox-launcher": "~0.1.2",
"karma-html2js-preprocessor": "~0.1.0",
"karma-jasmine": "~0.1.5",
"requirejs": "~2.1.9",
"karma-requirejs": "~0.2.1",
"karma-coffee-preprocessor": "~0.1.1",
"karma-phantomjs-launcher": "~0.1.1",
"karma": "~0.10.8",
"karma-ng-html2js-preprocessor": "~0.1.0"
```

Then run npm install again.
