HyperLedger Fabric v1.4.4：在mychannel上实例化智能合约，出现错误

Question

我正在遵循HyperLedger Fabric v1.4.4“编写第一个应用程序”教程[1，但是运行代码./startFabric.sh javascript时遇到问题：

+ echo 'Instantiating smart contract on mychannel'
Instantiating smart contract on mychannel
+ docker exec -e CORE_PEER_LOCALMSPID=Org1MSP -e CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/[email protected]/msp cli peer chaincode instantiate -o orderer.example.com:7050 -C mychannel -n fabcar -l node -v 1.0 -c '{"Args":[]}' -P 'AND('\''Org1MSP.member'\'','\''Org2MSP.member'\'')' --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --peerAddresses peer0.org1.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt

我认为该错误与docker映像有关，因为在执行以下代码时会发生该错误：

echo "Instantiating smart contract on mychannel"
docker exec \
  -e CORE_PEER_LOCALMSPID=Org1MSP \
  -e CORE_PEER_MSPCONFIGPATH=${ORG1_MSPCONFIGPATH} \
  cli \
  peer chaincode instantiate \
    -o orderer.example.com:7050 \
    -C mychannel \
    -n fabcar \
    -l "$CC_RUNTIME_LANGUAGE" \
    -v 1.0 \
    -c '{"Args":[]}' \
    -P "AND('Org1MSP.member','Org2MSP.member')" \
    --tls \
    --cafile ${ORDERER_TLS_ROOTCERT_FILE} \
    --peerAddresses peer0.org1.example.com:7051 \
    --tlsRootCertFiles ${ORG1_TLS_ROOTCERT_FILE}

我对Docker不太了解，但我正在学习。在那之前，有人可以帮助我解决这个问题吗？

我运行./byfn.sh up -l node时观察到相同的错误，但./byfn.sh up没有错误。我认为错误与布料垫片有关。我仍在寻找该错误的答案。

实例化智能合约的命令将尝试启动新的chaincode容器，但是失败，因为新的容器无法成功运行npm install命令。
