部署我的Rails应用程序时,我收到以下错误：

rake aborted!

有问题的文件是有效的,它适用于localhost.我也试过运行rake assests：在localhost上预编译,它全部通过.最后,我试图从文件中删除内容,git push和redeploy – 仍然得到相同的错误.只有完全删除文件并重新部署帮助.

会欣赏任何想法.

解决方法:

Here I found help for the same problem you had.

运行rails console和：

JS_PATH = "app/assets/javascripts/**/*.js"; 
Dir[JS_PATH].each do |file_name|
  puts "\n#{file_name}"
  puts Uglifier.compile(File.read(file_name))
end

它将显示文件和Uglifier出现问题的行.
