我在 AWS EC2 中有一个我们的应用程序的生产实例。我的团队在 Fedora 18 上进行本地开发。最近，在将代码推送到生产环境时，我们注意到在运行“rake assets:precompile”或“script/delayed_job start|stop”时出现分段错误。这些在我们的开发机器上运行良好。
为了尝试隔离问题，我们将 RBENV 从 1.9.3-p327 升级到 RBENV 1.9.3-p385。然后，为了尝试隔离 RBENV，我创建了一个新用户“testuser”，并使用 1.9.3-p385 全新安装了 RVM。同样的问题。
段错误细节似乎指向“therubyracer”宝石。我找不到任何看起来像我们的问题的信息。
