在生产中部署我的应用程序时出现问题...我的Gemfile包含gem'depaise'，一切正常，在开发中...
这是我的unicorn_stderr.log文件，其中[XXXXXX]是我的rails app文件夹。

我不明白这个问题......我用谷歌搜索了这个，但我发现什么都没有帮助我，我希望有人可以帮助我！
答案 0 :(得分：1)
我修复了它...我的script/rails和config/unicorn_init.sh不可执行，因此这些文件上的简单chmod u+x解决了我的问题。设计不是问题！

在我使用Devise部署新版本后，今天在生产服务器上也遇到了同样的问题。我读了很多主题，检查了所有配置文件，一切正常，但unicorn在日志文件中写了下一个：
错误-：未初始化的常量设计（NameError）
我的解决方案是：停止并启动独角兽守护程序。重新启动没有帮助。作为成功的标志-您需要检查/ tmp / pids /文件夹。当您停止该过程时，该文件夹将变为空。
