如何修复libmysqlclient.15.dylib未加载导致的错误？

我升级到Rails 2.2.2并安装了MySQL 2.7 gem，当我尝试运行迁移或启动服务器时看到此错误：

dlopen(/Library/Ruby/Gems/1.8/gems/mysql-2.7/lib/mysql.bundle, 9): Library not loaded: /usr/local/mysql/lib/mysql/libmysqlclient.15.dylib Referenced from: /Library/Ruby/Gems/1.8/gems/mysql-2.7/lib/mysql.bundle Reason: image not found - /Library/Ruby/Gems/1.8/gems/mysql-2.7/lib/mysql.bundle 

有什么问题？

Answer 1

我不得不从旧的引用中删除目录：

 sudo install_name_tool -change libmysqlclient.18.dylib /usr/local/mysql/lib/libmysqlclient.18.dylib /Library/Ruby/Gems/1.8/gems/mysql-2.7/lib/mysql.bundle sudo install_name_tool -change libmysqlclient.18.dylib /usr/local/mysql/lib/libmysqlclient.18.dylib /Library/Ruby/Gems/1.8/gems/mysql-2.7/mysql.bundle

为了别人的利益回答我自己的问题。

我在这里找到了修复。

跑：

 sudo install_name_tool -change /usr/local/mysql/lib/mysql/libmysqlclient.15.dylib /usr/local/mysql/lib/libmysqlclient.15.dylib /Library/Ruby/Gems/1.8/gems/mysql-2.7/lib/mysql.bundle sudo install_name_tool -change /usr/local/mysql/lib/mysql/libmysqlclient.15.dylib /usr/local/mysql/lib/libmysqlclient.15.dylib /Library/Ruby/Gems/1.8/gems/mysql-2.7/mysql.bundle 

为我工作。

Answer 3

使用sudo通常会导致意外问题。 对我有用的是卸载mysql2 gem并重新安装它。

gem uninstall mysql2 bundle

如果Gabe Hollombe解决方案不起作用，那么试试这个

 sudo install_name_tool -change libmysqlclient.15.dylib /usr/local/mysql/lib/libmysqlclient.15.dylib /Library/Ruby/Gems/1.8/gems/mysql-2.7/lib/mysql.bundle sudo install_name_tool -change libmysqlclient.15.dylib /usr/local/mysql/lib/libmysqlclient.15.dylib /Library/Ruby/Gems/1.8/gems/mysql-2.7/mysql.bundle
