【问题描述】：

所以我是第一次尝试启动 webrick 的 ruby​​ 新手。我最近刚刚用 mysql2 修复了分段错误错误，并遇到了这个新的退出问题。这是命令行读数：

G:\Ruby 开发\simple_cms>

G:\Ruby Development\simple_cms>rails 服务器

=> 启动 WEBrick

=> Rails 4.2.1 应用程序在 http://localhost:3000 开始开发

=> 运行 rails server -h 以获得更多启动选项

=> Ctrl-C 关闭服务器

退出

据我所知，我至少正在加载服务器。所以这不是分段错误的一部分，对吗？

我的 gemfile 包含 web-console 2.1.2。另外，为了以防万一，我已经运行了“捆绑安装”。对此错误有任何见解吗？让我知道是否需要更多信息。

Rails 版本 -4.2.1 Ruby 版本 - 2.2.1p85

【问题讨论】：

有谁知道我是否应该尝试早期版本的 ruby​​？

【参考方案1】：

有两个 rails 可执行文件。您的 PATH 将您指向错误的路径。输入'which rails'：你应该得到“~/bin/rails”，一个railties放在你的主目录中的存根。如果你得到别的东西，重命名那里的 rails 可执行文件，然后重试。

成功了！谢谢。 Rails 安装在一个驱动器上并试图指向另一个驱动器
