Question

I’d like to use twitter bootstrap manually, on my rails project.
But I’ve got this error, and some functions of bootstrap don’t work.

If you help me, I appreciate it. Thank you.

Errors on Console

<!-- as example, which doesn't work, somehow  -->

I believe everything necessary js and css files are in

• ./app/assets/images
• ./app/assets/javascripts
• ./app/assets/stylesheets

If you would like to add asset files ( like .js , .css or images ) in Rails >3 , you should use manifest files : application.js , application.css . After you copy sources in their directories , you should make declarations like this :

application.js :

//= require jquery
//= require jquery_ujs
//= require bootstrap
//= require bootstrap-responcive
//= require tree .

and in application.css:

*= require_self
*= require bootstrap
*= require_tree .

It makes useless including `<%= javascript_include_tag %> in your views .
