用指南针安装bootstrap sass

Question

I'm trying to install bootstrap-sass and getting the error below. I've tried an older version of sass but bundler keeps installing 3.3.0.

WARN: Unresolved specs during Gem::Specification.reset:
sass (~> 3.2)
WARN: Clearing out unresolved specs.
Please report a bug if this causes problems.

Answer 1

If you actually have the bootstrap-sass code checked out, change this line in the .gemspec:

s.add_runtime_dependency 'sass', '~> 3.3.0'

to

s.add_runtime_dependency 'sass', '~> 3.2.0'

After this, run bundle update sass , then bundle clean --force . The problem when downgrading the sass gem is that compass still tries to load the newer one, that's why you need the clean (or you could do a gem uninstall if it suits you better).

Answer 2

Install the gem

gem install bootstrap-sass

If you have an existing Compass project:

# config.rb:
require 'bootstrap-sass'

bundle exec compass install bootstrap

If you are creating a new Compass project, you can generate it with bootstrap-sass support:

bundle exec compass create my-new-project -r bootstrap-sass --using bootstrap

This will create a new Compass project with the following files in it:

• _variables.scss - all of bootstrap variables (override them here).
• styles.scss - main project SCSS file, import variables and bootstrap.

Some bootstrap-sass mixins may conflict with the Compass ones. If this happens, change the import order so that Compass mixins are loaded later.

I would recommend yeoman(bower/grunt) to manage your client side libraries. Not only will it download bootstrap with comapss and install it, it will make it easy to update and automatically recompile sass when a file is changed and reload the browser using life reload. It comes with grunt which you can setup to minify js,css and compress svg, png etc.
