cannot load such file -- v8 (in E:/work/store/app/assets/stylesheets/bootstrap_and_overrides.css.less)

1)rails新店

2)rails g 脚手架产品名称price:decimal --skip-stylesheets

3)耙db:migrate

4) 在 Gemfile 中: gem 'twitter-bootstrap-rails', :git => 'git://github.com/seyhunak/twitter-bootstrap-rails.git'

5) 捆绑安装

6)rails生成bootstrap:install少

7)浏览器:

重启后,错误重现。为什么?我喜欢说明: https://github.com/seyhunak/twitter-bootstrap-rails

/*
 * This is a manifest file that'll be compiled into application.css, which will include all the files
 * listed below.
 *
 * Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
 * or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path.
 *
 * You're free to add application-wide styles to this file and they'll appear at the bottom of the
 * compiled file so the styles you add here take precedence over styles defined in any styles
 * defined in the other CSS/SCSS files in this directory. It is generally better to create a new
 * file per style scope.

// If you'd like to override bootstrap's own variables, you can do so here as well

// @link-color: #ff0000;
