我在运行couchdb服务时遇到问题。 当我开始的时候，它只能在closures之前停留一秒钟左右。 这是一个例子 – 首先是状态命令，显示它是不活动的。 开始声称它正在运行，下一个状态命令说它是活动的，发出一个新的状态，一秒钟后说它失败了。 这是怎么回事？

问题在这些行中定义：

它试图find编译CouchDB束文件的ebin目录，但由于权限问题（eacces）而失败。 但是，原因是不在权限，但在path：为什么它在/根目录中寻找梁？ 可能是因为它没有检查所有其他选项（并且该服务以root身份运行，什么是坏的）。
唯一可能的答案是您有$ ERL_LIBSpathconfiguration错误。 它需要设置梁命令行参数，如-env ERL_LIBS $ERL_LIBS:/usr/lib64/couchdb/erlang/lib – 注意，这里的path应根据您的安装进行设置。
