Ruby on rails 资产：使用uglify预编译失败

你知道我该如何修复这个错误吗

环境

• 服务器：EC2（OpsWorks Rails应用程序）
• 操作系统：亚马逊2014.09
• Ruby:Ruby 2.0.0p645（2015-04-13修订版50299）[x86_64-linux]
• 轨道：4.0.8
• BowerRails:0.9.2（我也尝试了主分支的最新代码，但没有成功）
• 净现值：1.4.28
• 鲍尔：1.4.1
• ExecJS.runtime：我试过RubyRacerRuntime和Node.js，但它们都不能在我的服务器上运行

注

• assets:precompile

  在我的本地机器（mac）上运行良好
• 我发现在我的服务器上使用asset:precompile的唯一方法是注释掉

  config.assets.js_compressor=：uglifier

  。（但我想丑化）
• 在

  bower\u components/jquery/src/intro.js

  中，预编译总是失败（如果我手动修复intro.js中的语法错误，那么获取outro.js的错误）

错误
