【问题描述】：
我将一个 Rails 项目从一台机器移植到另一台机器上，并检查了以下清单以确保环境和系统设置良好：
1) 红宝石-v =>
ruby 2.0.0p195 (2013-05-14 revision 40734) [x86_64-darwin12.3.0]
2) 轨道 -v =>
/Users/AM/.rvm/gems/ruby-2.0.0-p195@global/gems/bundler-
1.3.5/lib/bundler/runtime.rb:216: warning: Insecure world writable dir

/Users/AM/.rvm/gems/ruby-2.0.0-p195@global/gems/bundler-
1.3.5/lib/bundler/runtime.rb:216: warning: Insecure world writable dir
/Users/AM/Documents/rubyws/overnights in PATH, mode 040777
Rails 4.0.0
3) 检查mysql是否正在运行：
4) 酿造更新
5) 捆绑安装
6)rake db:create....... 我在终端上收到以下消息：
AMs-MacBook-Pro:overnights AM$ rake db:create --trace

7) 我对此的理解是 MySql 已安装并正在运行，但不知何故，rails 应用程序找不到它：所以我做了“echo $PATH”
/Users/AM/.rvm/gems/ruby-2.0.0-p195/bin:/Users/AM/.rvm/gems/ruby-2.0.0-
p195@global/bin:/Users/AM/.rvm/rubies/ruby-2.0.0-
p195/bin:/Users/AM/.rvm/bin:/usr/local/bin:/usr/local/sbin:
~/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin
8) 然后我想找到 MySQL 的安装位置，所以我去了： cd /usr/本地/ ls -la
我看到了这个：
drwxrwxr-x 21 root admin 714 11 Jan 08:25 .
drwxr-xr-x@ 13 root wheel 442 1 Jun 2013 ..

drwxr-xr-x 17 AM admin 578 29 Aug 15:21 share
drwx------ 6 AM admin 204 11 Jan 08:33 var
所以我现在觉得我快到了，但需要最后几个步骤才能使这个 Rails 应用程序正常工作。有人可以帮我弄清楚下一步该怎么做吗？
谢谢
