我有一个使用工头 0.78.0 运行的 rails 4.2.1 应用程序
每当我尝试使用“puts”在控制台中记录一个值时，没有任何附加内容。我尝试用谷歌搜索一下，但没有找到可行的解决方案。
我试图在我的 development.rb 中添加 $stdout.sync = true 但到目前为止没有结果（是的，我重新启动了工头）
由于我的应用程序使用 angularjs 运行，因此当某些内容仅在服务器端附加而没有任何日志时，往往很难调试。
有没有办法在控制台中输出日志并解决这个问题？我知道这一定是配置问题，因为我的一些同事可以在同一个项目中做到这一点。我只是看不出他们和我的区别。
这是我启动工头时唯一能看到的输出。
