我有一个rails应用程序，我正在尝试推送heroku但是每次都失败了这条消息：
ExecJS::RuntimeError: SyntaxError: Unexpected token: eof (undefined) (line: 14023, col: 0, pos: 385975)
以及一些JS解析错误。我不知道在哪里查找此错误，因为没有给出文件名！我想知道我的application.js文件是否存在问题，即：
// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or any plugin's vendor/assets/javascripts directory can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// compiled file.
//
// Read Sprockets README (https://github.com/rails/sprockets#sprockets-directives) for details
// about supported directives.
//
//= require jquery
//= require jquery_ujs
另外，我有一个.coffee文件，我有每个js文件，但我只有一个application.js文件，而不是application.coffee文件。我需要一个吗？
另外，对于它的价值，我在运行
后出现此错误RAILS_ENV=production bundle exec rake assets:precompile
在尝试推送到heroku之前。
AND，在我的config / environments / production文件中，我改变了：
config.assets.compile = false
为：
config.assets.compile = true
请帮助!!
运行git push heroku master时的完整结果：
rake aborted!
