为什么rake中止[rake-tasks]无法在我的Windows盒子上加载这样的文件

Question

我正试图从一个没有rails或任何东西的目录中执行rake任务。里面只有一个目录和一个Rakefile.rb。

目前我不知道它为什么会失败。但我认为从Rakefile所在的目录中执行rake应该执行这个Rakefile文件中的任务。我是不是错过了加载路径？

我的环境

Win7 (x64)
ruby 1.9.3p194 (2012-04-20) [i386-mingw32]

这是错误信息

Answer 1

您可以尝试将Rakefile.rb重命名为Rakefile（不带.rb扩展名），然后重试吗？

也可以尝试如果：

rake -T -fRakefile.rb

工作。

Answer 2

在问题中，您编写了Reakefile.rb；我不知道这是否只是问题中的拼写错误，也不知道目录中的rakefile是否真的叫这个，但请确保它叫Rakefile或Rakefile.rb。
