在我将一台机器升级到 Mavericks 后，我遇到了麻烦，但我无法让 rails 再次运行。我尝试通过 brew 重新安装 mysql，重新安装 MAMP，重新安装 mysql2 gem。一切都是徒劳。我还尝试创建软链接(soft link)，如中所述 Unable to start server in rails with mysql db 这是我的错误:

我在这里看了答案Unable to start server in rails with mysql db当我运行命令时，没有任何改变，现在它告诉我该文件已经存在。
$ sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib
ln: /usr/lib/libmysqlclient.18.dylib: File exists
我对此感到非常沮丧。请帮忙!
最佳答案
我重新安装了一切。节点，rvm， ruby ，所有 gem 。它奏效了。
