尝试预编译资产时出错

Question

我在尝试部署应用程序时遇到此错误。我以前部署过这个应用程序，但由于某种原因，它现在无法预编译资产。

$ RAILS_ENV=production /tmp/myapp/rvm-auto.sh . bundle exec rake assets:precompile --trace
** Invoke assets:precompile (first_time)
** Execute assets:precompile
/usr/local/rvm/rubies/ruby-2.1.2/bin/ruby /var/www/myapp/shared/bundle/ruby/2.1.0/bin/rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets --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

尝试增加内存用于部署

在部署到 AWS Beanstalk 之前，我遇到了这个问题，该实例使用的是 1GB Ram 的 EC2 实例（但实际上只有 30% 的实例用于部署）。我升级到 2GB，一切都恢复正常了！
