如何化解？

通过在两个对等点中安装chaincode已经清除了它。这里我给出了通过。/startfabric.sh安装chaincode的代码片段

在peer1 0F组织中安装1

echo "Installing smart contract on peer1.org1.example.com"
docker exec \
  -e CORE_PEER_LOCALMSPID=Org1MSP \
  -e CORE_PEER_ADDRESS=peer1.org1.example.com:8051 \
  -e CORE_PEER_MSPCONFIGPATH=${ORG1_MSPCONFIGPATH} \
  -e CORE_PEER_TLS_ROOTCERT_FILE=${ORG1_TLS_ROOTCERT_FILE} \
  cli \
  peer chaincode install \
    -n fabcar \
    -v 1.0 \
    -p "$CC_SRC_PATH" \
    -l "$CC_RUNTIME_LANGUAGE"

在组织2的peer1中安装

echo "Installing smart contract on peer1.org2.example.com"
docker exec \
  -e CORE_PEER_LOCALMSPID=Org2MSP \
  -e CORE_PEER_ADDRESS=peer1.org2.example.com:10051 \
  -e CORE_PEER_MSPCONFIGPATH=${ORG2_MSPCONFIGPATH} \
  -e CORE_PEER_TLS_ROOTCERT_FILE=${ORG2_TLS_ROOTCERT_FILE} \
  cli \
  peer chaincode install \
    -n fabcar \
    -v 1.0 \
    -p "$CC_SRC_PATH" \
    -l "$CC_RUNTIME_LANGUAGE"

docker exec \
  -e CORE_PEER_LOCALMSPID=Org1MSP \
  -e CORE_PEER_MSPCONFIGPATH=${ORG1_MSPCONFIGPATH} \
  cli \
  peer chaincode invoke \
    -o orderer.example.com:7050 \
    -C mychannel \
    -n fabcar \
    -c '{"function":"initLedger","Args":[]}' \
    --waitForEvent \
    --tls \
    --cafile ${ORDERER_TLS_ROOTCERT_FILE} \
    --peerAddresses peer0.org1.example.com:7051 \
    --peerAddresses peer1.org1.example.com:8051 \
    --peerAddresses peer0.org2.example.com:9051 \
    --peerAddresses peer1.org2.example.com:10051 \
    --tlsRootCertFiles ${ORG1_TLS_ROOTCERT_FILE} \
    --tlsRootCertFiles ${ORG1_TLS_ROOTCERT_FILE} \
    --tlsRootCertFiles ${ORG2_TLS_ROOTCERT_FILE} \
    --tlsRootCertFiles ${ORG2_TLS_ROOTCERT_FILE}
