在部署到 rackspace 服务器之前，我必须运行 rake assets:precompile 命令，由于安全补丁和升级的 JSON GEM，最近将 rails 版本从 3.2.9 升级到了 3.2.11。
我收到以下错误并 rake abort。
$> rake assets:precompile --trace
** 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!

Tasks: TOP => assets:precompile
有什么解决方案吗？
