创建第一个Fabric创世区块，遇坑Failed to generate orderer genesis block
按上篇步骤到了创建创世区块了，然后失败了，报错如下

Failed to generate orderer genesis block...
google，stackflow,csdn,意见总结
就是 hyperledger-fabric-darwin-amd64-1.0.5.tar.gz版本与fabric samples新版（git clone https://github.com/hyperledger/fabric-samples.git）不符合，得下载最新版的hyperledger-fabric-darwin-amd64 ，以下是所有版本的地址，自己调对应系统的新版本吧
https://nexus.hyperledger.org/content/repositories/releases/org/hyperledger/fabric/hyperledger-fabric/
接着就是将解压后的bin,config文件夹都放入fabric samples里，以前的bin删掉。
重新运行 ./byfn.sh -m generate ，搞定如下：
Generating certs and genesis block for channel 'mychannel' with CLI timeout of '10' seconds and CLI delay of '3' seconds
Continue? [Y/n] y
proceeding ...
