Question

当我去运行我的应用程序时，我使用我的应用程序的主文件夹中的rails服务器启动服务器。当我使用127.0.0.1:3000查看我的应用程序主页时，它给了我这个错误（在Pages＃home中的Sass :: SyntaxError）;为什么我会收到此错误？

以下是我在命令行中的内容 ：

当我运行rails服务器并尝试在网络上本地加载我的应用主页 时，网页上显示了什么内容：

Answer 1

尝试bootstrap-sass-rails而不是bootstrap-sass。它适合在资产管道中使用，因此您不必乱用导入bootstrap-sprockets。 https://github.com/yabawock/bootstrap-sass-rails

Answer 2

您是否从终端运行bundle install然后重新启动服务器？如果是这样，我认为问题可能是application.css.scss文件中引用的apneadiving。

确保首先引导bootstrap-sprockets，如下所示：

application.css.scss

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

RoR中的（Sass :: SyntaxError in Pages＃home）是什么意思？
