Channel creation failed !!!!!!!!!!!!!!!!================== ERROR !!! FAILED to execute End-2-End Scenario ==================解決方法：make clean，再嘗試安裝，但是clean會刪除我們下載好的docker鏡像，這不是我們想要的，所以需要修改hyperledger/fabric/MakeFile 將第403行`-docker images -q $(DOCKER_NS)/fabric-$(TARGET) | xargs -I '{}' docker rmi -f '{}'`注釋掉。然后使用下面的命令清理掉這臺server上的所有容器：

?

docker ps -a|awk '{print $1}'|xargs -i docker stop {}docker ps -a|awk '{print $1}'|xargs -i docker rm {}
