在Fabric網路中建立通道時報錯：

Error: got unexpected status: FORBIDDEN -- config update for existing channel did not pass initial checks: implicit policy evaluation failed - 0 sub-policies were satisfied, but this policy requires 1 of the 'Writers' sub-policies to be satisfied: permission denied

原因通過configtxgen命令生成創世區塊時使用的通道名與建立通道時使用的通道名一樣，如下所示，channelID 與-c通道名均為amops

configtxgen -profile SampleMultiNodeEtcdRaft -channelID amops -outputBlock ./channel-artifacts/genesis.block
peer channel create -o agridepartorderer.amops.com:7050 -c amops -f ./channel-artifacts/channel.tx --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/amops.com/orderers/agridepartorderer.amops.com/msp/tlscacerts/tlsca.amops.com-cert.pem
 

將configtxgen指令中的channel修改成不一樣的即可

configtxgen -profile SampleMultiNodeEtcdRaft -channelID amopsdeploy -outputBlock ./channel-artifacts/genesis.block

重啟Fabric網路後解決如上問題

成功解決：Error: got unexpected status: FORBIDDEN -- config update for existing channel did not pass initial checks: implicit policy evaluation failed - 0 sub-policies were satisfied, but this policy requires 1 of the 'Writers' sub-policies to be satisfied: permission denied
