Question

我需要帮助，伙计们，我正在用2个Orgs开发定制的HLF网络，Fabric网络与cli完美地工作，当我想与node sdk连接时，就会出现错误。我正在开发自定义HLF网络与2Orgs.The Fabric网络是完美的工作与Cli，当我想连接与node sdk，然后错误来了。我成功地注册管理员，但未能注册用户和面临错误，而注册和注册用户1。你可以看到这个错误 和 ca集装箱日志.文件是提到下面的感谢提前

Answer 1

你的错误msg说，用户1已经在ca服务器上注册了，所以你必须重新启动网络，或者你必须从ca服务器上删除该身份。我建议你重启网络并删除钱包文件夹中的所有内容，然后就可以了。或者换个身份试试，比如用户

Answer 2

好像你已经注册了 "user1"。试着删除您注册时生成的本地文件，或者您应该动态地设置您的用户注册。
