bcos,生成NodeId的问题

[yeziyjy]

环境Ubuntu 16.04 LTS

1. 跟进操作步骤， 执行一键安装脚本build.sh，执行成功后结果为：bcoseth build succ! path: /usr/local/bin/bcoseth
2. 执行生成节点身份NodeId的操作， 执行命令：bcoseth --gennetworkrlp /mydata/nodedata-1/data/network.rlp 执行失败，返回如下信息：
   ubuntu@ubuntu:/mydata/nodedata-1/data$ bcoseth --gennetworkrlp /mydata/nodedata-1/data/network.rlp
