Question

我有一组非常简单的测试（来自Rails教程），但所有测试都因此错误而失败：

File to import not found or unreadable: bootstrap

任何想法发生了什么？

以下详细信息==================================

示例测试：

  describe "Help page" do
    it "should have the content 'Help'" do
        visit '/static_pages/help'
        expect(page).to have_content('Help')
    end
    # Title test.
      it "should have the right title" do
        visit '/static_pages/help'
        expect(page).to have_title("#{base_title} | Help")
      end
  end

测试失败消息：

8) Static pages Home page should have the base title
     Failure/Error: visit '/static_pages/home'
     ActionView::Template::Error:
       File to import not found or unreadable: bootstrap.

     # ./spec/requests/static_pages_spec.rb:14:in `block (3 levels) in <top (required)>'

我如何需要Bootstrap：

我在gemfile gem 'bootstrap-sass', '2.3.2.0'中导入bootstrap。
我在custom.css.sass文件中要求它：@import "bootstrap";。
我在application.css文件中要求它：*= require_self *= require_tree .

我的网站使用bootstrap的样式正确呈现。

Answer 1

如果某些人从rails 3.x升级到4并且他们的gemfile中仍然有group :assets do块，则会遇到此问题。在轨道4 you have to get rid of the assets group

从gem文件中删除“group：assets do”和“end”（如果存在）。

group :assets do
gem 'bootstrap-sass'
end

有这个错误的其他人只需重新启动服务器就可以修复它，还有一些人能够通过对lib / bootstrap-sass.rb文件的一个小改动来修复同样的错误，如同documented here一样。拉请求。

Answer 2

我在rails 4中遇到了同样的问题。我已经将“bootstrap”和“bootstrap-sprockets”导入到我的scss文件中，并且HTML页面工作正常，但是rake测试失败了。

我已经将gem'bootstrap-sass'添加到了group：test和：我的gemfile中的开发，如下所示：

group :assets, :test, :development do gem 'bootstrap-sass', '2.3.2.0 end

我不知道这是否是最佳解决方案，但它对我有用。

Rails - 测试失败，不包括bootstrap
