Lab 8.1: Balance Transfer Chaincode

go mod init, and go mod vendor errors in chaincode/balance_transfer. I cannot not use sudo to run the go mod commands.

I am open for suggestions. Please see below.

-VirtualBox:~/go/src/github.com/hyperledger/fabric-samples/chaincode/balance_transfer$ go mod init
go: creating new go.mod: module github.com/hyperledger/fabric-samples/chaincode/balance_transfer
go: updating go.mod: open /home/jimmys/go/src/github.com/hyperledger/fabric-samples/chaincode/balance_transfer/go.mod: permission denied

go mod vendor
Error permission denied

    Hi @jjsull1van,

    Try to update the permissions for the balance_transfer folder using chmod:

    sudo chmod -R 777 balance_transfer
    

    Afterwards, run the go commands once again.

    Best regards,
    Ilya

  • Hi There,
    i am facing altogether different issues.
    First go mod init did not worked for me.

    [email protected]:~/go/src/github.com/hyperledger/fabric-samples/chaincode/balance_transfer$ go mod init
    warning: GOPATH set to GOROOT (/usr/local/go) has no effect
    go: cannot determine module path for source directory /home/sv/go/src/github.com/hyperledger/fabric-samples/chaincode/balance_transfer (outside GOPATH, module path must be specified)
    
    Example usage:
        'go mod init example.com/m' to initialize a v0 or v1 module
        'go mod init example.com/m/v2' to initialize a v2 module
    
    Run 'go help mod init' for more information.
    

    Then i used as suggested

    [email protected]:~/go/src/github.com/hyperledger/fabric-samples/chaincode/balance_transfer$ go mod init balance_transfer
    warning: GOPATH set to GOROOT (/usr/local/go) has no effect
    go: creating new go.mod: module balance_transfer
    go: to add module requirements and sums:
        go mod tidy
    
    

    Then vendor command didnt worked.

    [email protected]:~/go/src/github.com/hyperledger/fabric-samples/chaincode/balance_transfer$ go mod vendor
    warning: GOPATH set to GOROOT (/usr/local/go) has no effect
    go: github.com/hyperledger/[email protected]: verifying go.mod: github.com/hyperledger/[email protected]/go.mod: open /usr/local/go/pkg/sumdb/sum.golang.org/latest: no such file or directory
    
    

    I checked the folder path of /usr/local/go/pkg which is read only. Only admins can modify.

    Not sure what is an issue. Also i noticed that GO always complain about GOPATH and GOROOT. I suspect this could be an issue?

    All my go env's are as below.

    [email protected]:~/go/src/github.com/hyperledger/fabric-samples/chaincode/balance_transfer$ go env

    FYI... I have extracted go zip in /usr/local/go/ while installing

    Am i missing anything here?
