Question

将Ruby on Rails 3.1.14与jRuby 1.7.6结合使用，我无法执行

RAILS_ENV=production RAILS_ENV=production /path/to/jruby -S rake --trace assets:precompile:all

设置以下选项时：

# config/environments/production.rb
config.assets.digest = false

它会产生以下堆栈跟踪：

** Invoke assets:precompile:all (first_time)
** Execute assets:precompile:all
** Invoke assets:precompile:primary (first_time)
** Invoke assets:environment (first_time)
** Execute assets:environment
** Invoke environment (first_time)
** Execute environment
** Invoke tmp:cache:clear (first_time)
** Execute tmp:cache:clear
** Execute assets:precompile:primary
rake aborted!

问题似乎发生在以下几行：

# actionpack-3.2.14/lib/sprockets/assets.rake:12
fork ? ruby(*args) : Kernel.exec(FileUtils::RUBY, *args)

我觉得这个exec语句不能与jRuby一起使用。仅当digest设置为true时才会执行此行。

这是一个rails bug吗？我在提交错误报告之前会问这里。

要完成此事：它肯定与jRuby不兼容，请参阅https://github.com/rails/rails/issues/12947以供参考。可悲的是，他们不会为Rails 3修复它。

Rails：jRuby 1.7.6中激活了'digest'的资产预编译失败
