我正在尝试学习 Rails，但遇到了一些我不明白的问题。我从 Hartl 的书开始，查看这条错误消息，它看起来与我为此所做的事情有关。

现在我在一个新项目中，当我尝试对我的路由文件运行测试时，我得到了这个。

您可能还没有运行 rake 任务来准备您的测试数据库：

bundle exec rake db:test:prepare

我也是 Rails 新手，遇到了一个非常相似的问题（在不同的项目上工作，但引用 Hartl 时出错）。在我的脑海中仔细考虑并使用谷歌搜索之后，我相信我找到了整体问题和解决方案。

不过，谁能解释一下 gems 中对 rails3tutorial 的引用以及如何删除它？

当我们开始 Rails 教程时，Hartl 建议我们运行以下命令：

$ rvm use 1.9.3@rails3tutorial2ndEd --create --default
Using /Users/mhartl/.rvm/gems/ruby-1.9.3 with gemset rails3tutorial2ndEd

（http://ruby.railstutorial.org/ruby-on-rails-tutorial-book?version=3.2#sec-install_rubygems）

结果？

...任何时候我们打开一个新的终端窗口，都会自动选择 1.9.3@rails3tutorial2ndEd Ruby/gemset 组合。

我通过运行解决了这个问题：

 rvm use 1.9.3-p484 --default

( http://rvm.io/gemsets/using )

这使得“常规”gemset 成为我们的默认 gemset（与我们自定义的 Hart 教程 gemset 不同）。我很确定“常规 gemset”是错误的术语，但我仍处于初学者阶段，所以我向所有知道正确术语的人道歉。我希望这会有所帮助！
