I am running ruby 2.4.0 and rails 5 with uglifier >=1.3. My code works locally and will compile in development mode. But when I try to deploy it to DigitalOcean with Capistrano I get an error with precompiling assets.
我正在使用uglifier> = 1.3运行ruby 2.4.0和rails 5。我的代码在本地工作，将在开发模式下编译。但是当我尝试使用Capistrano将其部署到DigitalOcean时，我得到了预编译资产的错误。
Here is the error reproduced locally:
以下是本地转载的错误：
RAILS_ENV=production rake assets:clean assets:precompile
rake aborted!
ExecJS::RuntimeError: SyntaxError: Unexpected token: name (parent)
JS_Parse_Error.Object.defineProperty.get ((execjs):3538:621)
any ideas? Here is the output of the assets:precompile in production.
有任何想法吗？以下是资产的输出：生产中的预编译。

Turns out my JS was not perfectly clean. I had some code let parent... whereas it should have been var parent.
原来我的JS并不是很干净。我有一些代码让父母...而它应该是var父母。
Thanks for your help.
谢谢你的帮助。

Try adding the below line to your Gemfile:
尝试将以下行添加到您的Gemfile：
group :assets do
gem 'uglifier'
end
Move that gem out of assets group
将该gem移出资产组
