Rails webrick 强制退出：未初始化的常量 WebConsole::Railtie::Middleware (NameError)
Rails webrick force-exits: uninitialized constant WebConsole::Railtie::Middleware (NameError)
所以我是 ruby 的新手，第一次尝试启动 webrick。我最近刚刚用 mysql2 修复了分段错误，并遇到了这个新的退出问题。这是命令行读数：

=> Run rails server -h for more startup options

据我目前的了解，我至少正在加载服务器。所以这不是分段错误的一部分，对吧？
我的 gemfile 包含 web-console 2.1.2。另外，我有 运行 'bundle install' 以防万一。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
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'：您应该得到“~/bin/rails”，railties 放在您的主目录中的一个存根。如果您得到其他东西，请在那里重命名 rails 可执行文件，然后重试。
