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 "copy:styles" (copy) task  Done, without errors.

Looking at the code that blows up in compass' compile method, what I find is the following:

child.stdout.pipe(process.stdout); 

This makes me think that child is undefined for some reason, and this variable comes from a call to grunt.util.spawn. This is where I am at a loss.

Am I missing any dependency? Am I missing any configuration?

Info:

• OS: Windows 8 x64
• node: v0.10.22

Answer 1

*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!)

Answer 2

On windows i had a few instalations of ruby:

    C:\ruby187 

and

    C:\Ruby200-x64 

install compass in both places, using:

    gem install compass 

this resolve my issue on windows 8 64bit
