运行rails new depot, 正常
运行rails g scaffold Product title:string description:text image_url:string price:decimal
运行rake db:migrate
运行rake test, 下面就出错了...
rake aborted!
stack level too deep
Tasks: TOP => test:units
(See full trace by running task with --trace)
运行bundle exec rake test, 输出为无限错误循环。

如果在 Rakefile 中加入include Rake::DSL, 再次运行 bundle exec rake test, 则错误输出结果为：

最让人崩溃的是：同样的示例，几个月前，同样的命令，新建的项目 (当时具体的 gem 版本不清楚), 但是有一点我可以确认，rake test是可以运行的。当时还使用autotest之类的自动化测试来着!!
太让人崩溃啦!! 谁来告诉我怎么回事儿？?
p.s. 其他 rake 任务貌似一切正常，就是 rake test, 另外，我的需求就是要让 test 跑起来，请大家帮我看看，是否新版本不再使用 rake test 这样的命令，又或者我缺少了某个版本的 gem. 总之，我犯的完全可能是低级小白错误，还望大家指点！
Rake DSL methods is deprecated. Google 一下 第一筆結果：Global access to Rake DSL method is depreciated
似乎之前碰到过类似的问题。莫名其妙就解决了。
** Invoke db:abort_if_pending_migrations (first_time)
看往后这一段似乎是死循环了
之前rake db:migrate成功了吗？手动rake db:test:prepare一下试试看？
或者切换 Ruby/Rails 版本试试？
#7 楼 @lgn21st 真没想过。 #8 楼 @daqing 那太谢谢你啦。https://github.com/zw963/depot1.git 其实我没有做什么啊，没有一行我自己的代码。rake test 还有 rake cucumber 就不成功。
rake db:migrate 当然成功啦。 rake db:test:prepare 没有提示，应该没问题？
我换过 3.2.1 , 3.1.0 , 3.2.6 三个版本都一样。也在两个电脑上试过，问题依旧。(难道跟系统有关？我是 slackware , 可是我用的是 rvm, 应该跟系统无关啊)
git clone https://github.com/zw963/depot1.git
cd depot1/
rvm 1.9.3-p0
rvm gemset create depot
rvm gemset use depot
bundle install
rake db:migrate
rake test
rvm 1.9.2-p290
rvm gemset create depot
rvm gemset use depot
bundle install
rake test
rake test:units
rake test:functionals
我这边没有问题
$ rvm 1.9.2@depot
$ ruby -v
ruby 1.9.2p290 (2011-07-09 revision 32553) [i686-linux]
$ rvm -v
rvm 1.9.2 by Wayne E. Seguin ....
$ rake --version
rake, version 0.9.2.2
$ gem list | grep rake
rake (0.9.2.2)
$ rvm 1.9.3@depot
$ ruby -v
ruby 1.9.3p0 (2011-10-30 revision 33570) [i686-linux]
$ rake --version
rake, version 0.9.2.2
$ gem list | grep rake
rake (0.9.2.2)
没有添加任何include Rake::DSL 就成功了！
唯一特殊的配置就是：去掉了 Gemfile 当中，therubyracer 那一行之前的注释。
剩下的要说有啥不一样，那就是我在.bashrc 内设定了
export RUBYLIB=$HOME/bin/ruby/lib
export RUBYOPT=-raddition
其实就是__~/bin/ruby/lib/addtion.rb, 里面启动加载了个人以前整理的类，以及初始加载了一些 Ruby 默认没有混入的库，我先去试试，去掉以上选项正常不。
