Answer 1

可能这篇文章与你的问题相似:库未加载:libmysqlclient.16。运行'rails server'

Answer 2

试试这个:

export DYLD_LIBRARY_PATH="$DYLD_LIBRARY_PATH:/usr/local/mysql/lib/"

将其放入.profile(或.bashrc)中，并键入以下命令

my_term> source .profile

将"/usr/local/mysql/lib/"替换为mysql客户端的安装位置

Answer 3

从安装程序重新更新MySQL(例如，mysql-5.5.10-osx10.6-x86_64)。

mysqll2 gem:$ sudo gem install mysql2 -- --with-mysql-config=/usr/local/mysql-5.5.10-osx10.6-x86_64/bin/mysql_config

Answer 4

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

Answer 5

我也有这个问题，我在这里或其他问题中发现的任何建议都没有让我去任何地方，而是像root一样运行(与sudo rails s)。我猜当作为根运行时，它使用mysql库的正确路径，但是用install_name_tool更改它，正如这里的一个链接中所描述的那样，也不起作用。只要我没有发现问题，我需要用sudo启动我的rails应用程序。
