Cannot use grunt on simple Yeoman angular

Question

Trying to just startup a simple angular app via Yeoman, using steps in this guide http://www.sitepoint.com/kickstart-your-angularjs-development-with-yeoman-grunt-and-bower/ and get this error when trying to run `grunt` or `grunt server`: ``` Loading "Gruntfile.js" tasks...ERROR Error: Cannot find module 'load-grunt-tasks' Warning: Task "default" not found. Use --force to continue. ``` Here are my versions: ``` yo --version && grunt --version && bower --version 1.1.2< grunt-cli v0.1.13 grunt v0.4.4 1.3.1 ``` See screencast of this in action: http://screencast.com/t/4ToPw3SlL2

Accepted Answer

I just encountered the same problem today, managed to resolve it with the answers here.

Basically I needed to update npm to latest version, by using this command (the npm which came with Node-v0.10.29 package was outdated)

```
npm update npm -g
```

or

```
sudo npm update npm -g (i used this command on my mac)
```

Then type this command

```
npm --version (it should show 1.5.0-alpha-4 or later version)
```

Then type the grunt serve command

```
grunt serve
```

If you still have issues, then try running these commands

```
npm install 
```

or

```
sudo npm install (i used this command on my mac)
```

Then try grunt serve command again,

```
grunt serve
```

This time, it worked for me.

If it didn't, then try this command

```
bower install (i did not have to use this command)
```
