Yeoman for Angular, then "grunt serve" won't start

Question

This is the first time I use yeoman to setup the scaffolding for an AngularJS app, and I have to admit I am likely new to the nodeJS, grunt and bower world. So, here's what I've done so far: I made sure yeoman, grunt-cli and the angular-generator packages are installed ``` npm install -g yo grunt-cli bower npm install -g generator-angular ``` Generated my app ``` yo angular ``` I also tried: ``` yo angular --min-safe ``` So far, al seems good. Between the options given, I choose the Twitter Bootstrap one, no angular dependencies, and to overwrite my local .gitignore file. After all that, I try to run my app: ``` grunt serve ``` At this point, grunt complains that it is not locally installed into the project, so I run: ``` npm install grunt --save-dev ``` No again, trying to run the app: ``` grunt serve ``` And this is where I get blocked: ``` C:\Projects\what-now>grunt serve Running "serve" task Running "clean:server" (clean) task Running "concurrent:server" (concurrent) task Running…

Accepted Answer

*sighs*, sorry.

All it took me is to write this question to then figure out I needed to have installed Ruby and the compass gem. Now it makes sense: the process for compiling would not spawn up.

After installing Ruby, run:

```
gem install compass
```

And you should be good to go.

EDIT: After you install Ruby, you need to make sure that the ruby runtime files' path is added to your PATH variable. (Thanks JagWire!)
