跑步：

bundle exec rake assets:precompile RAILS_ENV=production --trace

** Execute assets:precompile:primary
rake aborted!
TypeError: Object doesn't support this property or method
  (in C:/Sites/MyApp/app/assets/javascripts/application.js)

以下是 的全部内容application.js：

//= require jquery
//= require jquery_ujs
//= require_tree .

没有别的了。

我试图从中删除 //= require三行application.js，然后预编译运行没有问题。

看起来这可能是 uglifier 和 Windows 脚本主机的问题：

https://github.com/rails/rails/issues/2847

确保您使用的是最新版本的 uglifier (1.0.4)。如果您仍然遇到问题，我建议您尝试不同的编译器（例如 Closure 编译器）

在Gemfile：

gem 'closure-compiler'

在config/environments/production.rb

config.assets.js_compressor = :closure

或者完全禁用 JS 压缩：

config.assets.compress = false

并且做了

bundle update

这带来了

uglifier (2.1.1)

（除其他外），然后：

rake assets:precompile

这解决了我的问题。Windows，Rails 3.2.11。
