No route matches [GET] "/assets/bootstrap.css.map"

I'm running on rails4, bootstrap 3 and I get the following error message in my terminal. 

Started GET "/assets/bootstrap.css.map" for 127.0.0.1 at 2014-08-24 23:41:36 -0700

Anyone have any ideas how to get rid of this?

EDIT:

This is my application.css

*= require_tree .
*= require_self
*= require_ladda-themeless
*= require login_form
*= require bootstrap

my error: ActionController::RoutingError (No route matches [GET] "/assets/bootstrap.min.css.map"):

I created an empty bootstrap.min.css.map in assets folder, the error stopped.

The file that requests the bootstrap.css.map is:

/vendor/assets/stylesheets/bootstrap.css

And removing this last line should fix the problem:

/*# sourceMappingURL=bootstrap.css.map */

See here what are map files used for.

I had the same problem and found this short answer on SO. From what I understand the map files are an aid to debugging tools in the browser. Quick fix is to find where this map file is included, by issuing a command line find. 

find . -name "*.css" -o -name "*.scss" | xargs grep 'sourceMappingURL=bootstrap.css.map'

Then either delete the line from your css file or move it to where it will be looking for it.

Ok, so instead of having native bootstrap files under the app/assets folder, I just created custom.css.scss under app/assets/stylesheets and included @import "bootstrap"; Then, I removed all the bootstrap files from app/assets folder which solved the problem.
