I have done basic setup in Hyperledger Fabric 1.4.7 and made all peer's to join the channel. After exploring chaincode in golang, I started trying chaincode install command and I was facing issue's in this step.

error

Error: error getting chaincode code mycc: path to chaincode does not exist: /home/user899/go/src/chaincode

When I just ran go run chaincode.go

error

chaincode.go:7:2: cannot find package "github.com/hyperledger/fabric-chaincode-go/shim" in any of: /usr/lib/go-1.14/src/github.com/hyperledger/fabric-chaincode-go/shim (from $GOROOT) /home/user899/go/src/github.com/hyperledger/fabric-chaincode-go/shim (from $GOPATH) chaincode.go:8:2: cannot find package "github.com/hyperledger/fabric-protos-go/peer" in any of: /usr/lib/go-1.14/src/github.com/hyperledger/fabric-protos-go/peer (from $GOROOT) /home/user899/go/src/github.com/hyperledger/fabric-protos-go/peer (from $GOPATH)

Environments

echo $GOPATH
/home/user899/go

Chaincode location
/home/user899/SoloNetwork/chaincode

Can anyone help.

Thanks

I'm answering my own question. Here is the solution, I was not aware of the directory structure that need's to be followed in Go.

So first, I checked my GOPATH(usually the workspace where we can write all our go files) using go env in the terminal it was located under home/dev/go

And coming about the directory structure it should be followed as following :-

$GOPATH + /src/github.com/chaincode, So the final structure will be home/dev/go/src/github.com/chaincode inside chaincode. I can place all Go files.

So after getting chaincode file from here, I have placed in the above location and executed the following commands

  • go mod init
  • go mod tidy

Then, I was able to execute peer chaincode install commad

peer chaincode install -n mycc -p "github.com/chaincode" -v 1.0

Here in the command -p "github.com/chaincode" is the folder name that I have created.

So finally chaincode path is created by these : $GOPATH + src + -p flag

If anyone is facing, go binary related issue's set your GOROOT path to the bin location where go is intalled.
