我尝试手动创建first-network而不是使用byfn.sh脚本，当我尝试在cli容器中创建通道时。
peer channel create -o orderer.example.com:7050 -c mychannel -f ./channel-artifacts/channel.tx --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
我收到此错误：
Error: got unexpected status: BAD_REQUEST -- error authorizing update: error validating DeltaSet: policy for [Group] /Channel/Application not satisfied: Failed to reach implicit threshold of 1 sub-policies, required 1 remaining
来自orderer的错误：
ERRO 008 Principal deserialization failure (the supplied identity is not valid: x509: certificate signed by unknown authority (possibly because of "x509: ECDSA verification failure" while trying to verify candidate authority certificate "ca.org1.example.com")) for identity
注意：的
如果我使用byfn.sh脚本
，它的工作正常我发现了这个
peer channel creation fails in Hyperledger Fabric，
hyperledger fabric first_network example create channel got BAD_REQUEST，
FABRIC returns Error: Got unexpected status: BAD_REQUEST个问题
但我仍然不知道如何修复此错误？
os主持人： ubuntu 16:04

如果仍然出现此错误，则可能已经尝试启动网络，然后重新开始。您需要同时删除旧的Docker容器及其卷-可能会尝试重用它们，然后使用旧的证书数据，从而导致unknown authority错误。
以下是您要用于byfn.sh或类似脚本的所有重置命令：
# STOP AND DELETE THE DOCKER CONTAINERS
docker ps -aq | xargs -n 1 docker stop
docker ps -aq | xargs -n 1 docker rm -v
# DELETE THE OLD DOCKER VOLUMES
docker volume prune
# DELETE OLD DOCKER NETWORKS (OPTIONAL: seems to restart fine without)
docker network prune
# DELETE SCRIPT-CREATED FILES
rm -rf channel-artifacts/*.block channel-artifacts/*.tx crypto-config
rm -f docker-compose-e2e.yaml
# VERIFY RESULTS
docker ps -a
docker volume ls
ls -l

在开始手动步骤之前，请尝试按BYFN进行操作。我认为以前的卷没有清除。
