我对scala和couchbase相对较新，但我需要快速学习。最近，当尝试通过Scala使用Java couchbase SDK运行示例应用程序时，我遇到了以下问题。

修改
我对此有点新意，但这是我设法从调试器中解脱出来的。

编辑2：
我查看了Couchbase控制台日志，我不断获得以下内容
Service 'memcached' exited with status 1. Restarting. Messages: Failed to open library "/Users/luishreis/Downloads/couchbase-server-enterprise_4/Couchbase Server.app/Contents/Resources/couchbase-core/lib/memcached/stdin_term_handler.so": dlopen(/Users/luishreis/Downloads/couchbase-server-enterprise_4/Couchbase Server.app/Contents/Resources/couchbase-core/lib/memcached/stdin_term_handler.dylib, 6): image not found
Unable to load extension /Users/luishreis/Downloads/couchbase-server-enterprise_4/Couchbase Server.app/Contents/Resources/couchbase-core/lib/memcached/stdin_term_handler.so using the config
对此事的任何帮助都将不胜感激。
非常感谢。
