bootstrap-sass: Undefined variable: “$baseLineHeight”
I’ve integrated bootstrap into my app using bootstrap-sass. The app works fine on my local machine, but when I go to deploy via capistrano, I get this error:
Undefined variable: “$baseLineHeight”.
When the capistrano attempts to run assets:precompile
I think this variable is throwing the error because it is the first variable in the first scss file that is attempted to be precompiled.
Something isn’t loading up right. Any ideas what it might be?

Added application.rb and production.rb to gist
You’ve edited your
production.rb file so that Rails will attempt to precompile all CSS/JS files (line 48).
By default Rails will only precompile
application.css(.scss). By adding the wildcard selector to
config.assets.precompile you are asking Rails to precompile every css asset in your application, including Sass partials. Naturally, this is probably not the behaviour you wish for.
# Precompile additional assets (application.js, application.css, and all non-JS/CSS are already added) config.assets.precompile += %w( *.css *.js )
Rails will therefore iterate over each css asset, compiling them. It so happens that
_accordion.css.scss is the first Bootstrap asset it comes across, and Rails will attempt to compile that first.
_accordion isn’t independent, and requires some files to be loaded before it, hence the error. It should never be compiled as a separate file anyway.
You need to change your
config.assets.precompile to add only the additional files that you need aside from
You need to make sure the import of all your css is done in the proper order. For variables to work it needs to be one of the first few css files to be loaded.

Initially I had the similar problem
Sass::SyntaxError: Undefined variable: “$alert-padding”. problem with this line in the
Rails.application.config.assets.precompile += [/.*\.css/]
Don’t know why but for me it helped to change it to this line
Rails.application.config.assets.precompile += [/^[-_a-zA-Z0-9]*\..*/]
After it the problem was solved and everything worked in production.
