HyperLedger Fabric中对等体上的Chaincode安装

Question

I am trying to test my chaincode locally, for this I have a script to run, but whilst installation of chaincode(code below) getting error that chaincode path does not exists?

peer chaincode install -n mycc -v 1.0 -p ./bitbucket.org/Foldername/testBlockchain/folder_name_for_chaincode

in all of the examples I have seen following command is used

peer chaincode -n mycc -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02

My question precisely is that how can I correct my path to point to chaincode?

Answer 1

You need to have your chaincode available in the GOPATH, then you should be able to install it. Just either add your bitbucket folder into GOPATH or move you chaincode into $GOPATH/src .

Update

The following command

peer chaincode install -n mycc -v 1.0 -p ./bitbucket.org/Foldername/testBlockchain/folder_name_for_chaincode

need to be replaced with

peer chaincode install -n mycc -v 1.0 -p bitbucket.org/Foldername/testBlockchain/folder_name_for_chaincode

Answer 2

Step a)
get the channel name using the following

peer channel list

step b)
get the chaincode version using this 

peer chaincode list --installed

step c)
install the chaincode using this

CORE_PEER_ADDRESS=peer0.org1.example.com:7051 peer chaincode install -n mycc -p github.com/lc/go -v v3 


-n=name,
-v=version,
-p=path

Thanks for your answer. My chain code is already in $GOPATH. Directory structure is as follows. Directory structure is as follows

$GOPATH                                                                                                              ->src       
    --->bitbucket.org
