Question

我尝试使用Capistrano将我的Rails应用程序部署到AWS。

在我运行cap production deploy之后，我收到了一条'Rake Aborted'消息，其中包含以下内容：

ExecJS::ProgramError: SyntaxError: Unexpected character '’' (line: 19420, col: 10, pos: 548371)

这不会给我一个语法错误的特定位置，我该如何找到它？提前谢谢！

一种更通用的方法来查找使用此代码的问题：

运行rails console

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

它会显示文件和Uglifier出现问题的行。
