Ruby on rails Rails-不包括引导的测试失败

我有一组非常简单的测试（来自Rails教程），但所有测试都会因以下错误而失败：

要导入的文件找不到或不可读：引导

知道发生了什么吗

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

我如何要求引导：

  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

我在我的gem文件中导入引导

gem'bootstrap sass'，'2.3.2.0'

我在custom.css.sass文件中需要它：

@import“bootstrap”

我在application.css文件中需要它：

*=require\u self
*=需要树。

---

并且我的站点通过引导的样式正确呈现

如果一些人从rails 3.x升级到4，并且他们的文件中仍然有一个

group:assets do

块，那么他们就会遇到这个问题。在rails 4中

从GEM文件中删除“组：资产do”和“end”（如果存在）

group :assets do
gem 'bootstrap-sass'
end

---

有此错误的其他人可以通过简单地重新启动服务器来修复此错误，还有其他人可以通过对lib/bootstrap-sass.rb文件的一个小更改来修复与拉请求中相同的错误。

我在rails 4中遇到了相同的问题。我已经将“bootstrap”和“bootstrap链轮”导入到我的scss文件中，HTML页面运行良好，但rake测试失败

我已将gem“bootstrap sass”添加到我的gemfile中的groups:test和：development，如下所示：

组：资产，：测试，：开发do
gem“引导式sass”，“2.3.2.0”
结束

我不知道这是否是最好的解决方案，但它对我有效
