Lab 8.1 Balance Transfer Exercise Go errors

SumitVedpathak

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

sv@Sumit:~/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

sv@Sumit:~/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.

sv@Sumit:~/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/fabric@v1.4.7: verifying go.mod: github.com/hyperledger/fabric@v1.4.7/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.

sv@Sumit:~/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?

@ SumitVedpathak
Hello, Let us see if we can determine what's happening. So if I am understanding the issue correctly you are stuck on Lab 8.1 at the point where you are attempting to import the client Identity Library?

Thats Correct.
I know its permission issue with /usr/local/go, which has readonly access. So i can go and run chmod command to give permission to this folder, but is this the right way?
Moreover, go is also complaining about, same path for GOPATH and GOROOT. Ideally what it should be?
