这是一个奇怪的问题。我在运行 rake 进行测试时遇到此错误，但在迁移时却没有。我正在运行 RVM，下面的 shell 转储应该提供您需要的任何信息。

任何帮助将不胜感激。我见过其他几个人遇到这个问题，但还没有对我（或他们）有用的解决方案。

谢谢。

我已经升级到最新的 Rails - 3.2.6。即使我使用'bundle exec'，错误仍然存​​在。（这对 3.2.6 来说并不新鲜——我仍然在 3.1 下遇到问题） undefined 方法是新的。

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

gem 'rake', ">=0.9.2" # 在你的 Gemfile

然后

$捆绑安装

然后

$ bundle exec rake

如果以上不起作用：

$ rvm all do gem install rake -v 0.9.2.2#install rake to all ruby​​ 版本

然后再次运行 rake

如果您正在使用 bundler（并且使用 rails，您可能会这样做），请始终像这样运行 rake：

bundle exec rake

这将获取您的 Gemfile 中指定的宝石。
