hyperledger-fabric - 状态 : 500, 消息:无法获取链码包

Question

root@93272a1da547:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer chaincode instantiate -o orderer.example.com:7050 --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n fabrep -v 1.0 -c '{"Args":["init","a", "100", "b","200"]}' -P "OR ('Org1MSP.member','Org2MSP.member')"

在尝试实例化我的链代码时，出现以下错误:

2018-06-19 09:03:09.526 UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 001 Using default escc
2018-06-19 09:03:09.526 UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 002 Using default vscc
Error: Error endorsing chaincode: rpc error: code = Unknown desc = chaincode error (status: 500, message: cannot get package for chaincode (fabrep:1.0))

谁能告诉我这是什么意思？以及如何解决错误？

Answer 1

• 首先检查节点上是否安装了chaincode

• $ peer chaincode list --installed

• 并使用已安装链代码的确切名称运行实例化命令
