我（完全）是 ROR 的新手，并且有一个需要维护和升级的应用程序。我有源代码，正在尝试使用db:migraterake 命令构建数据库。我已经开始使用 Aptana Studio 进行开发。当我运行时dg:migrate，出现以下错误：

rake db:migrate
(in G:/Projects/.../.../trunk)
MissingSourceFile no such file to load -- rcov/rcovtask

rake aborted!

我也安装了 hpricot gem（0.8 版）。

对此有何补救措施？

也许您的系统找不到宝石。这可能是路径问题，有关详细信息，请参阅此帖子。

最显着的错误是

rake aborted!
no such file to load -- hpricot

你需要杏。您可以在命令行上运行以下命令安装它

gem install hpricot
