Global Flags:

      --cafile string              Path to file containing PEM-encoded trusted certificate(s) for the ordering endpoint

      --logging-level string       Default logging level and overrides, see core.yaml for full syntax

  -o, --orderer string             Ordering service endpoint

      --test.coverprofile string   Done (default "coverage.cov")

!!!!!!!!!!!!!!! Channel creation failed !!!!!!!!!!!!!!!!

================== ERROR !!! FAILED to execute End-2-End Scenario ==================

解决方法：

make clean，再尝试安装，但是clean会删除我们下载好的docker镜像，这不是我们想要的，所以需要修改hyperledger/fabric/MakeFile 将第403行`-docker images -q $(DOCKER_NS)/fabric-$(TARGET) | xargs -I '{}' docker rmi -f '{}'`注释掉。

然后使用下面的命令清理掉这台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 {}
