Fail to instantiate the chaincode in first network of fabric-samples - hyperledger-fabric

Question

The official hyperledger fabric v1.0.0 gives a simple demo by using docker.
What i am doing is to avoid docker and directly run them on the machine. Thanks to the answer from my previous question, I have successfully launched 1 solo orderer, two peers (each from one org), created and joined the channels from peers, installed the chaincode on two peers.
The client side's command to install chaincode is
peer chaincode install -n myC1 -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02
Both peers return the following message and I think it should be correct.
2017-09-11 16:34:26.361 SGT [chaincodeCmd] checkChaincodeCmdParams -> INFO 001 Using default escc
2017-09-11 16:34:26.361 SGT [chaincodeCmd] checkChaincodeCmdParams -> INFO 002 Using default vscc
2017-09-11 16:34:26.556 SGT [main] main -> INFO 003 Exiting.....
However, when i try to instantiate the chaincode as follows
peer chaincode instantiate -o orderer.example.com:7040 --tls $CORE_PEER_TLS_ENABLED --cafile $ORDERER_CA -C $CHANNEL_NAME -n myC1 -v 1.0 -c '{"Args":["init","a","100","b","200"]}' -P "OR ('Org1MSP.member','Org2MSP.member')
Client console returns the error message
2017-09-11 17:00:18.181 SGT [chaincodeCmd] checkChaincodeCmdParams -> INFO 001 Using default escc
2017-09-11 17:00:18.181 SGT [chaincodeCmd] checkChaincodeCmdParams -> INFO 002 Using default vscc
Error: Error endorsing chaincode: rpc error: code = Unknown desc = Failed to init chaincode(handler not found for chaincode myC1:1.0)
The console of Peer0.org2 gives NO error message. But Peer0.org1's console gives the following:
2017-09-11 17:00:18.183 SGT [chaincode] Launch -> ERRO 032 sending init failed(handler not found for chaincode myC1:1.0)
2017-09-11 17:00:18.184 SGT [endorser] simulateProposal -> ERRO 033 failed to invoke chaincode name:"lscc" on transaction a665c5305c5e3f158d272e4a39b04611e5335406e2a7c7057f11d32d8e07670e, error: Failed to init chaincode(handler not found for chaincode myC1:1.0)
Can any one help me to solve this problem and give me a simple explanation??
