找不到在Windows 7上运行的自定义链码路径Hyperledger Fabric V1.0本地网络

I am trying to install my custom chain code in my local Hyperledger Fabric v1.0 environment.

For this I have followed the documentation build your first network and I am using first network sample with in the github project. No it is up and running with ./byfn.sh -m up and executing all the scripts for channel creating, chain code installation and instantiation and all by running script.sh file.

Now I have changed the following to tryout my custom chaincode

peer chaincode install -n mycc -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02>&log.txt

this I have changed to

peer chaincode install -n mycc -v 1.0 -p github.com/myuserId/fabrcicV1_chaincodes/mychaincode >&log.txt

Now by running ./byfn.sh -m up getting the exception

!!!!!!!!!!!!!!! Chaincode installation on remote peer PEER0 has Failed !!!!!!!!!!!!!!!!
========= ERROR !!! FAILED to execute End-2-End Scenario ===========

I have the repository there in github, then why it is not showing does not exit?

I have cloned the same to Windows 7 machine under the path $GOPATH/src/github.com/ and given local path, then also I am getting the same error. I am running all the commands through docker quick start terminal for windows 7.

Please suggest where I am doing wrong.

Also in some of the network log I have found a location /opt/gopath/src/github.com/.... and where it is pointing to. In my windows path gopath is /c/users/public/fabricv1.

Since I am not much familiar with the tool, please comment on this also.

After doing some analysis from my side, it seems like the chain code is reading from some pre-mounted directories sacc/, fabcar/, /marble02 , chaincode_example_02, hyperledger/ under the path root@7785f8b27559:/opt/gopath/src/chaincodedev/chaincode# and chaincode also pre-loaded at the time of making the network up using docker image. There it seems no effect by adding chaincode in windows folder and it is from the above said virtual machine path.

So what can I do now to continue my work? is there any way to install my custom chaincode to the local network. I tried with my githhub path and local path but no use. please somebody help :(

    It seems that you do not have your chaincode in the $GOPATH, you need to run:

    go get github.com/myuserId/fabrcicV1_chaincodes/mychaincode
    

    Before trying to install the chaincode on peer, in your case where you are using build your first network, you need to make sure your new chaincode inside fabric-samples/chaincode folder. And also note that you need to mount folder with your chaincode into docker cli container, see example of current docker-compose-cli.yaml file:

    volumes:
        - /var/run/:/host/var/run/
        - ./../chaincode/:/opt/gopath/src/github.com/hyperledger/fabric/examples/chaincode/go
        - ./crypto-config:/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/
        - ./scripts:/opt/gopath/src/github.com/hyperledger/fabric/peer/scripts/
        - ./channel-artifacts:/opt/gopath/src/github.com/hyperledger/fabric/peer/channel-artifacts
    

    In particular, you probably need to replace here with your chaincode or make sure to mount an additional folder within $GOPATH of cli container:

    - ./../chaincode/:/opt/gopath/src/github.com/hyperledger/fabric/examples/chaincode/go
