Ruby on rails RubyonRails安装过程

首先，我安装了Ruby 2.2.1 x 64版本的安装程序 从这个网站

然后使用命令行

gem install rails

然后我下载了devkit并安装了它

DevKit-mingw64-64-4.7.2-20130224-1432-sfx.exe

然后开始创建rails应用程序

rails new app -d mysql

但启动服务器时出错

rails server

它说：

请帮忙

运行

bundle install

后是否有任何错误？实际上没有错误。当我执行rails新应用程序-d mysql时，我不需要运行“bundle install”，对吗？不，如果不取消，它会自动运行。尝试卸载并重新安装mysql2，需要完整的错误回溯来调查您的问题。如果不是很明显，在我看来它肯定是MySQL错误。再一次，我认为我的新手错误是Rails的问题。。。我遇到过这样的问题，除了在Mac上。。。让我从某处挖掘我的问题。。。没关系，似乎是我使用RubyMine的问题，希望你能想出一个解决办法！
