1 CORE_PEER_ADDRESS=peer:7051 CORE_CHAINCODE_ID_NAME=charity:0 ./charity 提示不存在charity（目录中确实没有这个文件）
2 删除charity这几个字母后，按步骤到peer chaincode instantiate -n charity -v 0 -c '{"Args":[]}' -C myc，提示handler not found for chaincode charity
3 根据网上教程，此情况由端口号引起，应设置为7052，直接设置CORE_PEER_ADDRESS=peer:7052 CORE_CHAINCODE_ID_NAME=charity:0，运行peer channel create -c myc -f myc.tx -o orderer:7050即bad request
4 修改yaml文件仍然无效

1、按照流程安装和准备完毕，执行以下命令：
peer chaincode invoke -n charity -c '{"Args":["donation", "mike", "2000"]}' -C myc
报错：
Error: Error endorsing invoke: rpc error: code = Unknown desc = could not find chaincode with name 'charity' - make sure the chaincode charity has been successfully instantiated and try again -
2、以为是初始化的问题，接着我先去尝试install：
peer chaincode install -p chaincodedev/chaincode/charity -n charity -v 0
报错：
Error: Error endorsing chaincode: rpc error: code = Unknown desc = chaincode error (status: 500, message: Error installing chaincode code charity:0(chaincode /var/hyperledger/production/chaincodes/charity.0 exists))
3、已存在，然后去init：
peer chaincode instantiate -n charity -v 0 -c '{"Args":[]}' -C myc
报错：
Error: Error endorsing chaincode: rpc error: code = Unknown desc = Failed to init chaincode(handler not found for chaincode charity:0)

请指教！

when i use docker-compose to run this project, it not work, cli alwarys restart . this is log:
