Rake doc：rails错误

尝试生成Rails API文档，但遇到错误：

$ rake doc:rails
rake aborted!
undefined method `task' for #<DummyApp::Application:0x00000100dd14d0>

之前有过类似的东西，我不得不将我的佣金（0.9）降级回0.8.7。虽然我升级了我的宝石;我应该再次降级还是有办法解决这个问题并继续使用Rake 0.9？

更新：

降级为Rake 0.8.7后：

使用@ Zabba的方法：

No Rakefile found (looking for: rakefile, Rakefile, rakefile.rb, Rakefile.rb)

编辑Rakefile后

。

提前致谢！

Answer 1

Rake 0.9.0有这个问题。 要修复它，要么降级到rake 0.8.7或继续使用rake 0.9.0并在应用程序目录根目录中My_app_name::Application.load_tasks的{​​{1}}之前添加以下内容：

Rakefile

Answer 2

将其放在Gemfile中，然后改为使用bundle exec rake：

gem 'rake', '0.8.7'
