ruby-on-rails - Ruby 3.2.3 rake 似乎不起作用 - 或者什么的。 rake 中止!无法加载此类文件

Question

所以我正在尝试从 Lynda.com 学习 Ruby 和 Rails 当我到达数据库部分时，老师让我们用 rake 做这个模式转储，但是它中止了，我不知道出了什么问题(我是新手对于这一切，请原谅我 =))

操作系统:狮子
ruby : ruby 1.9.3p194(2012-04-20 修订版 35410)[x86_64-darwin11.3.0]
rails : rails 3.2.3
rake : rake (0.9.2.2)
$PATH:/usr/local/Cellar:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/本地/bin:/usr/X11/bin

所有的 gem 都应该是最新的(前几天刚重新安装过)。如果您需要了解任何其他信息来帮助进行故障排除，请告诉我!

这是我遇到的错误:

Alex$ rake db:schema:dump
rake aborted!
cannot load such file -- bundler/setup

(See full trace by running task with --trace)

当我尝试重新安装 budel 并运行此命令时得到这个:
