在尝试运行rake时，遇到以下错误：

...和跟踪：

的Gemfile：

来源'http://rubygems.org'

gem'rail'，'3.0.7'
  宝石'耙'，'〜＆gt; 0.8.7'
  gem'sqlite3-ruby'，：require =＆gt; 'sqlite3的'

我意识到其他人已经报告了这个错误并提出了同样的问题 - 发布的解决方案对我的问题没有影响。我尝试过这里列出的每个解决方案：Undefined method 'task' using Rake 0.9.0。

Answer 1

如果你继续使用0.9.0，请将以下内容复制到你的Rakefile：

module ::AppName
  class Application
    include Rake::DSL
  end
end

module ::RakeFileUtils
  extend Rake::FileUtilsExt
end

就在

之前

AppName::Application.load_tasks

干杯，

Answer 2

Rails 3.0.8.rc1已经使用rake 0.9.0解决了这个问题，请参阅此提交：https://github.com/rails/rails/commit/83f257fc4862642af29056cb5b7dfef6e1303754

使用rake 0.9.0和0.8.3的未定义方法'任务'
