删除Ruby中所有文件的方法

Question

I will probably kick myself after this but I have created a method within my cucumber application that will delete all files in a directory but it doesn't seem to execute as the files still exist after running it, though if i jump into my console and run the commands step by step it works.

Any reason why this would not work when calling the method itself?

def clean_reports
  js_error_path = File.join(File.dirname(__FILE__), '/report/js_errors')
  screenshot_path = File.join(File.dirname(__FILE__), '/report/screenshots')
  FileUtils.rm_rf(Dir.glob(js_error_path + '/*'))
  FileUtils.rm_rf(Dir.glob(screenshot_path + '/*'))
end

What would be handy is if I could just call FileUtils.rm_rf just once? is this possible?

My directory structure is like so

-cucumber_tests
  -report
   -js_errors
     (files)
   -screenshots
     (files)

Thanks

以下行将有所帮助，

FileUtils.rm_rf(Dir['./report/js_errors', './report/screenshots'])
