[英]RoR Precompiling Assets fail while rake assets:precompile - on basically empty application.js
Running: 运行:
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)
Here is the entire content of application.js
: 以下是application.js
的全部内容:
//= require jquery
//= require jquery_ujs
//= require_tree .
nothing else there. 没有别的。
I tried to remove the three //= require
lines from application.js
, the precompilation then runs with no problems. 我试图从application.js
删除三个//= require
行,然后预编译运行没有问题。
Looks like it might be a problem with uglifier and Windows Script Host: 看起来它可能是uglifier和Windows Script Host的问题:
https://github.com/rails/rails/issues/2847 https://github.com/rails/rails/issues/2847
Make sure you're using the last version of uglifier (1.0.4). 确保您使用的是最新版本的uglifier(1.0.4)。 If you're still having problems, I'd suggest trying a different compiler (eg Closure compiler) 如果你还有问题,我建议尝试不同的编译器(例如Closure编译器)
In Gemfile
: 在Gemfile
:
gem 'closure-compiler'
In config/environments/production.rb
在config/environments/production.rb
config.assets.js_compressor = :closure
alternatively disable JS compression altogether: 或者完全禁用JS压缩:
config.assets.compress = false
I got same sort of error 我有同样的错误

and did 并做到了
bundle update
which brought in 引进来的
uglifier (2.1.1)
(amongst other things), then: (除其他外),然后:
rake assets:precompile
and that resolved my problem. 这解决了我的问题。 Windows, Rails 3.2.11. Windows,Rails 3.2.11。
