Error compiling CSS asset

[burtondav]

I renamed my apllication.css to application.css.scss.
I added this line to it:

Import twitter bootstrap @import "twitter/bootstrap";

I get:
Sass::SyntaxError: File to import not found or unreadable: twitter/bootstrap.

[ZephiroRB]

Hey remove
gem 'bootstrap-sass'

and restart server 💃

[rothlis]

I had this issue as well: File to import not found or unreadable: variables.

I "fixed" the issue by added the full path to all imports in bootstrap/_bootstrap.scss. For example, @import "variables"; would become @import "twitter/bootstrap/variables";

Any idea how to fix this properly?

[yury]

@rothlis it very likely that you forget require option in

gem 'anjlab-bootstrap-rails', '>= 3.0.0', require: 'bootstrap-rails'

[gfrey]

Had this issue with failed compilation of CSS asset, too. Blame emacs's scss-mode. It tried to compile the file (failed because missing load_paths for twitter/bootstrap from the gem) and generated some output (containing the mentioned message and some stacktrace) rails happily served.

[danmaz74]

I had this problem, and fixed by including the bootstrap gem before the rails_admin gem.

[danpe]

I'm having the same issue, is there any fix?
