rails服务器错误？ （铁轨3）

现在我收到这个？

跟踪/ BPT陷阱
可能是这篇文章与你的问题类似： 库未加载：尝试在OS X 10.6上使用mysql2 gem运行’rails server’时出现libmysqlclient.16.dylib错误
试试这个：
export DYLD_LIBRARY_PATH="$DYLD_LIBRARY_PATH:/usr/local/mysql/lib/"
将它放在.profile（或.bashrc）中并键入此命令
my_term> source .profile
用MySQL客户端安装的地方替换’/ usr / local / mysql / lib /’
从安装程序再次更新MySQL（例如， mysql-5.5.10-osx10.6-x86_64 ）。
然后MySQL2 gem： $ sudo gem install mysql2 -- --with-mysql-config=/usr/local/mysql-5.5.10-osx10.6-x86_64/bin/mysql_config
它对我有用。
对于永久性修复，尝试通过命令创建软链接 –
sudo ln -s /usr/local/mysql/lib/libmysqlclient.16.dylib /usr/lib/libmysqlclient.16.dylib

我也有这个问题，我在这里或其他问题找到的任何建议都没有让我到处找，但是以root身份运行（使用sudo rails s ）。 我想当以root身份运行时，它使用了mysql库的正确路径，但是使用install_name_tool更改它，如其中一个链接所述也不起作用。 只要我没有找到问题，我需要用sudo启动我的rails应用程序。
