I am a newbie in GOlang and Hyperledger fabric, I was just configuring the environment. But I got a weird error that is given bellow
user1@NTP-145UBUNTU:~$ go env
GOARCH="amd64"
GOBIN=""
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/usr/lib/go-1.6/bin"

CXX="g++"

user1@NTP-145UBUNTU:~$ sudo go get -u github.com/hyperledger/fabric-sdk-go
[sudo] password for user1:
package github.com/hyperledger/fabric-sdk-go: cannot download, $GOPATH not set. For more details see: go help gopath
It is saying that my GOPATH env variable is not set. I have configured it and its is showing in evn variable list also. If anyone in here faced this issue please help me. please note : I am using ubuntu 16 LTS
thanks in advance.
You are executing go get with sudo. That will cause all your env variables to be lost, as the command gets executed as user root.
Usually this should not be necessary. $GOPATH is usually set to $HOME/go/. This is also the default value. You should set $GOPATH to this value. After that you do not have to call go get with sudo.
And as pizza lord suggested, you should update your go version.
Remove the existing golang version packaged with ubuntu. Update you golang version to 1.9 or latest .
$ sudo apt-get remove golang-go
$ sudo apt-get remove --auto-remove golang-go
$ sudo add-apt-repository ppa:gophers/archive
$ sudo apt-get update
$ sudo apt-get install golang-1.10-go
Update ~/.bash_profile with golang variables
export PATH=$PATH:"/usr/lib/go-1.10/bin"
export GOPATH=$HOME/go
There are 2 possible mistakes
$GOPATH correctly.try this.
mkdir ~/go-workspace
and in your .bashrc file, append this
export GOPATH=~/go-workspace
go get with sudo.try :
go get -u github.com/hyperledger/fabric-sdk-go
if you get permission denied error, try
sudo chown user1 $(echo $GOPATH)
