Question

我正在努力获取我的第一个rails应用程序，但无论出于何种原因，当我运行命令$rails server时，我的终端会抛出这个错误：

我在Stack Overflow上找不到任何内容。有什么想法吗？

Answer 1

您需要在启动时安装Rails使用的必需gem。在您运行rails s之前，请务必运行bundle install或bundle update。

Answer 2

确保您的Gemfile有一行如下所示：gem 'jquery-rails'

然后从项目目录：bundle install

Answer 3

因为在Rubygems服务器上，该版本显示：

2.0.0 December 20, 2011 yanked

无法运行rails服务器
