Question

我知道这些问题之前已经得到解答但是我无法启动我已经设置的rails服务器。有人在Unable to start rails server发布了完全相同的错误，但我无法使用它来解决问题。我真的很新，所以非常感谢你的帮助。

其他任何一个链接都没有与您的问题相同，这两个问题都出现在旧版mysql2宝石中，但是没有完整路径libmysqlclient.16.dylib，请注意您的错误完整路径Library not loaded: /usr/local/mysql/lib/libmysqlclient.16.dylib（其他问题没有）。

你的问题是lib可能不存在，因为那不是MySQL将在大多数OSX系统中安装的地方。

假设你已经安装了MySQL，你应该有一个名为mysql_config的命令 - 你想通过将安装程序指向这个文件来安装你的gem。然后，安装人员可以使用mysql_config的输出为所需的所有MySQL库找到合适的位置。

无聊，只想要答案？

sudo gem install mysql2 -- --with-mysql-config=`which mysql_config`

无法启动rails服务器
