Rails webrick出口:未初始化的常量WebConsole：：Railtie：：NameError

Question

所以我是红宝石公司的新手，第一次尝试开始工作。最近，我用mysql2修复了分段错误，并遇到了这个新的退出问题。下面是命令行的内容：

据我所知，至少到目前为止，我正在加载服务器。所以这不是分割错误的一部分，对吗？

我的web文件包括web-控制台2.1.2。另外，我还运行了“包安装”，以防万一。对这个错误有什么见解吗？如果还需要更多的信息，请告诉我。

Rails版本-4.2.1 Ruby版本- 2.2.1p85

有两个rails可执行文件。你的道路指向了错误的方向。键入‘哪个rails'：您应该得到"~/bin/rails"，这是railties放在主目录中的存根。如果您得到了其他内容，请重新命名rails可执行文件，然后再试一次。
