昨天在使用 bundle 的时候 使用了命令：bundle clean --force
只见输出:
Remove Gem activerecord
Remove Gem xxx
Remove Gem xxx
Remove Gem xxx
Remove Gem xxx
Remove Gem xxx
果断ctrl + c 程序结束后。回到项目中 rake -T 输出：
lioooo:deploy lioooo$ rake -T
rake aborted!
cannot load such file -- active_record/deprecated_finders
查看 Gemfile 依赖的 gem 包：
source "http://ruby.taobao.org"
gem "colored", "1.2"
gem "activerecord", "3.2.3"
gem "logging", "1.8.1"
gem "pry", "0.9.10"
gem "capistrano", "2.9.0"
gem "capistrano_colors", "0.5.5"
gem "capistrano-ext", "1.2.1"
gem "rake-hooks", "1.2.3" #rake callback gems
再次回到项目根目录执行命令：bundle install 输出：
Using rake (10.0.3)
Using i18n (0.6.4)
Using multi_json (1.7.2)
Using activesupport (3.2.3)

Using pry (0.9.10)
Using rake-hooks (1.2.3)
Using bundler (1.3.5)
Your bundle is complete!
Use `bundle show [gemname]` to see where a bundled gem is installed.
结束后执行命令 rake -T 输出：
lioooo:deploy lioooo$ rake -T
rake aborted!
cannot load such file -- active_record/deprecated_finders
同样的错误 !!!!!!!!!
执行命令 bundle show activerecord 输出
The gem activerecord has been deleted. It was installed at:
/usr/local/Cellar/ruby/1.9.3-p125/lib/ruby/gems/1.9.1/gems/activerecord-3.2.3
提示 activerecord-3.2.3 已经被删除。果然 gem list activerecord 结果输出：
gem list activerecord
*** LOCAL GEMS ***
activerecord (4.0.2, 3.2.16, 3.2.14, 3.2.11, 3.2.8, 3.2.3, 3.2.2, 3.2.1, 3.2.0, 3.0.10, 2.3.11, 2.3.8)
于是奇怪的问题就出现了：bundle 提示 activerecord-3.2.3 已经被删除，但是gem list 却能找到该版本的activerecord
难道 gem list 有什么缓存信息？gem list 是列举出系统 gem env 目录中所有安装的 gem.
这个时候我需要做什么来挽救当前环境呢？

不过可以先把 "Gemfile.lock" 删除了，然后执行 bundle install

It was installed into /usr/local/Cellar/ruby/1.9.3-p125/lib/ruby/gems/1.9.1/cache
等执行完毕后，使用命令 bundle exec rake -T 就可以列举出 task
但是如果不用bundle exec的话还是有错误。这个我就比较疑惑了.难道 bundle install 不会把 gem 安装到 env 系统的目录中去？之前一直是这样安装的啊。
