Ruby on rails 引导链轮错误：要导入的文件找不到或不可读：引导链轮

我正在尝试在我的应用程序中实现引导，我不断地遇到一些以前启动应用程序时从未遇到的错误。我浏览了一个答案，我一直在寻找的唯一答案是删除Gemfile中我没有的

资产

部分，并重新启动服务器，我已经多次这样做了，但都没有成功。下面是错误和我的文件。如果需要提供其他服务，请告诉我。谢谢大家!

浏览器错误：

要导入的文件找不到或不可读：引导链轮

我看到您的gem文件中有

gem'bootstrap'

和

gem'bootstrap sass'

。如果删除其中一个，请运行

bundle

，并按照相应github站点上的安装说明进行操作，链轮应该可以工作。另外，我的

application.scss

文件通常没有所需的部分。

1º）在您的gem文件中安装以下gem：

gem 'bootstrap-sass', '~> 3.3.6'
gem 'autoprefixer-rails'

2º）发出以下命令：

mv app/assets/stylesheets/application.css app/assets/stylesheets/application.css.sass

3º）编辑pp/assets/stylesheets/application.css.sass并附加以下行：

@import "bootstrap-sprockets"
@import "bootstrap"

//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require bootstrap-sprockets
//= require_tree .

4º）编辑您的app/assets/javascripts/application.js文件，并确保其包含以下行：

@import "bootstrap-sprockets"
@import "bootstrap"

//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require bootstrap-sprockets
//= require_tree .

5º）现在运行

bundle install

你准备好了！这个食谱对我一直都很有效，而且它很受欢迎

希望有帮助

问题：要导入的文件找不到或无法读取引导链轮

@导入“引导链轮”； @导入“引导”

解决方案：

gem“rails”、“5.0.0.1” gem“引导式sass”，“3.3.6”

是否安装捆绑包

---

然后重新启动rails服务器

尝试删除此文件

application.scss

中的所有注释，并只保留两行

@import

谢谢psantos！我只是做了些改变，但没用。我对我原来的帖子进行了编辑。我忘了包括rails服务器中出现的其他错误，以防有助于理解这个问题。您不需要

bootstrap

gem，只需要

bootstrap sass

谢谢Benjamin。我所遵循的教程让我将两者都包括在内，但我只能假设这是一个错误。使用

bootstrap sass

而不是

bootstrap

是否意味着您使用的是bootstrap 3而不是4？jbk，您也应该发布您的答案，而且这是一个信息性的注释，是您的注释。我无法理解对正确答案的否决票。这将不再有效，因为现在我们有了Rails5，但它在发布时是正确的答案。无论如何，谢谢。
