试图访问我的红宝石项目

 

我试图访问我的第一个红宝石项目。 在导航到正确的目录并键入以下内容之后：

$ rails服务器

我收到以下错误消息：

我以前使用RVM安装了mysql2 gem。 我知道这可能是一个简单的解决方法，但我是新手，所以我感谢你的帮助。

一些额外的信息：

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

你有看看如何解决“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“？

它看起来可能是一个类似的问题 

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

把它放在bash.profile中，像魅力一样工作

我尝试了以上所有内容，但都没有成功。 我在另一个页面上发现了这个问题库未加载：libmysqlclient.16.dylib错误，当试图在OS X 10.6上运行'rails server'时，使用mysql2 gem并且它的工作方式类似于魅力：

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