Hyperledger Fabric can t load package package github com hyperledger fabric core chaincode shim

Question

I am trying to install Hyperledger Fabric prerequisites. I have installed the go in usr/local/go and set the path. But when i run 

make cryptogen

I get this error:

can't load package: package github.com/hyperledger/fabric/core/chaincode/shim: cannot find package

"github.com/hyperledger/fabric/core/chaincode/shim" in any of:

/usr/local/go/src/github.com/hyperledger/fabric/core/chaincode/shim (from $GOROOT)

/usr/local/go/bin/src/github.com/hyperledger/fabric/core/chaincode/shim (from $GOPATH) find:

‘/usr/local/go/bin/src/github.com/hyperledger/fabric/core/chaincode/shim’: No such file or directory

Answer 1

You can install various golang projects with the $GOPATH variable. e.g.

export GOPATH=/home/username/go
mkdir -p $GOPATH/src/github.com/hyperledger
cd $GOPATH/src/github.com/hyperledger
git clone -b master https://github.com/hyperledger/fabric-samples.git
cd fabric-samples

The fabric-samples source tree can then be accessed from:

$GOPATH/src/github.com/hyperledger/fabric
