解决方案的想法？是否有其他方法供我下载？我不想通过MacPorts安装它，因为在安装时，自制软件会抱怨

我不知道我现在是否违背了某种礼仪，因为我已经发布了这篇文章，但我还没有得到任何回应，因为我非常想继续我的度假计划，所以我求助于我的同事StackOverflovian

肯定是这个

配置：错误：找不到js库

是否安装了Mozilla SpiderMonkey库？

如果只是为了开发，为什么不使用couchbase.org上的couchbase单服务器安装程序呢。通过这种方式，您可以获得最新版本的CDB，从而省去了自己编译CDB的麻烦。您的生产设置很可能是一个Linux机箱，在这里编译CDB要容易得多

We couldn't detect gcc 4.2.x. Some formulae require this compiler.
NOTE: Versions of XCode newer than 4.2 don't include gcc 4.2.x.
