css - Bootstrap 不路由 CSS 或 JavaScript？没有路由匹配 [GET] "/css/bootstrap.css"

Question

• rails 4.1.1
• ruby 2.0
• Webrick 服务器

我正在尝试让 bootstrap-sass 在开发中第一次工作。我尝试按照 GitHub 说明、Bootstrap 网站说明和其他几个视频进行操作，看起来我可以安装 gem、拖放文件、更新 application.css.scss 文件和在应用程序索引页面中引用 css 文件，在 View 中调用一些 css，它会起作用。

当我检查页面的源代码(其中包含我放入 application.index.erb 文件中的 Bootstrap 引用)以确认 Bootstrap 正在运行时，出现错误。代码在那里，但我点击 css 链接以确认它的工作并得到这个:

No route matches [GET] "/css/bootstrap.css"

这是我的 application.css.scss 文件:

/*
 * 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.
 *
 *= require_tree .
 *= require_self
 */

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

即使我处于开发模式，我也将生产文件设置为:

  config.serve_static_assets = true

一定是路由问题，但我无法弄清楚为什么我的 Assets 管道无法在开发模式下使用 css 和 js？

此外，这是我的 gem 文件:

所以我设法通过以下方式解决了这个问题:

ExecJS::RuntimeError in Users#index (RoR)

尽管它说删除“//= require_tree”忽略了这个问题，但我四处走动试图修复在我安装 node.js 并更改 UTF 信息后不断出现的 ExecJS 错误16 到 8。我删除了 require_tree 评论，尽管有人建议我绕过它。

我敢肯定以后会有更多错误，但根据我的研究，Windows 和 ExecJS 似乎存在不兼容问题。我是 Ruby 的新手，所以我认为它真的与与之关联的 gem 有关吗？例如，我尝试了 therubyracer gem(如其他帖子所建议的那样)并需要 gems 但它想要安装 python 但失败了。

无论如何，我进一步阅读，ExecJS 和 Windows 有很多问题，似乎可以通过过渡到基于 linux 的开发服务器来解决。

无论哪种方式，这现在对我有用。
