耙分贝：迁移（MySQL的）

Question

可能重复：
Library not loaded: libmysqlclient.16.dylib error when trying to run 'rails server' on OS X 10.6 with mysql2 gem

为什么我得到这个错误？什么意思？

我已经安装了mysql2宝石， “sudo的创业板安装mysql2”

的Gemfile：

gem 'mysql2'

把这段代码在.profile和.bash_profile文件中。

alias ll="ls -lahG" 
alias whereami="pwd" 

export PATH="/Applications/MAMP/bin:/usr/local/bin:/usr/local/sbin:usr/local/my$ 
export DYLD_LIBRARY_PATH="/usr/local/mysql/lib:$DYLD_LIBRARY_PATH" 

注意：如果你不知道该怎么做，在终端每次打开它的时候......

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

这是我的.bash_profile文件看起来像这样类型编辑你的bash，在根（$）终端菜单中，输入ls -la，然后输入nano .bash_profile和/或nano .profile进入bash的文本编辑器（我只是保持它们都一样，它可能是多余的，不知道）。

一旦完成编辑，点击ctrl-X，然后点击'返回'返回到主菜单，可以这么说。
