Question

我不知道wtf是怎么回事，但我刚创建了一个新的Rails应用程序，无法让任何rake任务工作或显示在$ rake -T

lib / tasks / hello.rake

namespace :hello do 
  desc "hello"
  task :you do 
    puts "hello"
  end
end

$ rake -T

它没有出现在那里

$ rake hello:you

耙子流产了！不知道如何建立任务'你好'你'（见--tasks）

Answer 1

如果您想要一个非常完整的所有rake任务列表，您需要运行 rake -T -A。

我希望有所帮助。

Answer 2

我遇到了这个问题，但这是由于我没有提供任务说明。将desc 'Hello World'添加到我的task块上方之后，该任务就会显示在列表中。

Answer 3

可能是您给任务指定了.rb扩展名而不是.rake

我的rake任务没有出现在rake -T中
