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！
