HyperLedger结构链码未更新

我正在尝试遵循Hyperledger结构代码示例: https://github.com/hyperledger/education/tree/master/LFS171x/fabric-material

最初,我替换了chaincode/tuna-app/tuna-chaincode。使用我的go文件链码/金枪鱼应用程序/测试。去测验go通过其initLedger函数调用在分类帐中初始化的内容发生了更改。它工作得很好,在tuna app/中不需要任何更改。startFabric。sh。

现在,当我再次尝试通过initLedger函数调用更改分类帐时,它没有发生。即使我对函数本身进行了注释,它仍然显示分类帐的旧内容。

如何使用可见的更改更新链码?

startFabric。sh包含以下代码:

set -e

# don't rewrite paths for Windows Git Bash users
export MSYS_NO_PATHCONV=1

starttime=$(date +%s)

if [ ! -d ~/.hfc-key-store/ ]; then
    mkdir ~/.hfc-key-store/
fi

# launch network; create channel and join peer to channel
cd ../basic-network
./start.sh

# Now launch the CLI container in order to install, instantiate chaincode
# and prime the ledger with our 10 tuna catches
docker-compose -f ./docker-compose.yml up -d cli

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/Admin@org1.example.com/msp" cli peer chaincode install -n tuna-app -v 1.0 -p github.com/test-app
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/Admin@org1.example.com/msp" cli peer chaincode instantiate -o orderer.example.com:7050 -C mychannel -n tuna-app -v 1.0 -c '{"Args":[""]}' -P "OR ('Org1MSP.member','Org2MSP.member')"
sleep 10
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/Admin@org1.example.com/msp" cli peer chaincode invoke -o orderer.example.com:7050 -C mychannel -n tuna-app -c '{"function":"initLedger","Args":[""]}'

printf "\nTotal execution time : $(($(date +%s) - starttime)) secs ...\n\n"
printf "\nStart with the registerAdmin.js, then registerUser.js, then server.js\n\n"

我尝试在对等链码实例化后添加以下行:

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/Admin@org1.example.com/msp" cli peer chaincode upgrade -o orderer.example.com:7050 -C mychannel -n tuna-app -c '{"function":"initLedger","Args":[""]}'

但它给出了以下错误:

Error: Chaincode version is not provided for upgrade

当我将upgrade语句更改为:

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/Admin@org1.example.com/msp" cli peer chaincode upgrade -o orderer.example.com:7050 -C mychannel -n tuna-app -v 1.0 -c '{"function":"initLedger","Args":[""]}'

错误更改为:

Error: Error endorsing chaincode: rpc error: code = Unknown desc = chaincode error (status: 500, message: version already exists for chaincode with name 'tuna-app')
