试图访问我的ruby项目 – 与mysql有关的LoadError

我正在尝试访问我的第一个ruby项目。 导航到正确的目录并键入：

$ rails服务器

我收到以下错误消息：

我之前使用RVM安装了mysql2 gem。 我知道可能有一个简单的修复，但我是新手，所以我感谢你的帮助。

一些额外的信息：

Rozey $哪个ruby
/Users/Rozey/.rvm/rubies/ruby-1.9.2-p180/bin/ruby
Rozey $ mysql
在/ usr /本地/ MySQL的/斌/ MySQL的

Answer 1

你有没看过如何修复“dlopen（/Library/Ruby/Gems/1.8/gems/mysql-2.7/lib/mysql.bundle,9）：库未加载：/ usr / local / mysql / lib / mysql /libmysqlclient.15.dylib“？

看起来它可能是一个类似的问题

Answer 2

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

把它放在bash.profile中并像魅力一样工作

Answer 3

我尝试了以上所有内容，但没有一个有效。 我发现这个在另一个页面上没有加载：libmysqlclient.16.dylib在尝试使用mysql2 gem在OS X 10.6上运行’rails server’时出错 ，它就像一个魅力：

sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib
