这是有效的Go路径配置吗？

I've placed my path variables as follows:

export GOROOT=/usr/local/go
export GOPATH=$HOME/Professional/Sch/Fabric/go
export GOBIN=/usr/local/go/bin
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin

I've placed these lines in both ~/.profile and ~/.bashrc and sourced them both (not sure which of them is taking effect).

my go env output:

GOARCH="amd64"
GOBIN="/usr/local/go/bin"
GOCACHE="/home/deepak/.cache/go-build"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/home/deepak/Professional/Sch/Fabric/go"
GORACE=""
GOROOT="/usr/local/go"
GOTMPDIR=""
GOTOOLDIR="/usr/local/go/pkg/tool/linux_amd64"
GCCGO="gccgo"
CC="gcc"
CXX="g++"
CGO_ENABLED="1"
CGO_CFLAGS="-g -O2"
CGO_CPPFLAGS=""
CGO_CXXFLAGS="-g -O2"
CGO_FFLAGS="-g -O2"
CGO_LDFLAGS="-g -O2"
PKG_CONFIG="pkg-config"
GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build653871525=/tmp/go-build -gno-record-gcc-switches"

I've placed the following code in $HOME/Professional/Sch/Fabric/go/hellp.go:

package main

import "fmt"

func main() {
    fmt.Printf("Hello, World!
")
}

but each time i do go install hellp.go, I get:

go install command-line-arguments: open /usr/local/go/bin/hellp: permission denied

which is strange because go version returns a go version go1.10.4 linux/amd64, and I'm not sure why its trying to reference /usr/local/go/bin/hellp as there is no 'hellp' file there, its a sample file I created at $HOME/Professional/Sch/Fabric/go/.

I'm not sure which directory permission is missing, but I've tried:

  201  sudo chmod -R 777 ~/Professional/Sch/Fabric
  202  go install hellp.go 
  203  sudo chmod -R 777 ~/Professional/Sch/Fabric/go/hellp.go 
  204  go install hellp.go 
  205  sudo chmod -R 777 ~

My uname -a output:

Linux instance-1 4.9.0-8-amd64 #1 SMP Debian 4.9.110-3+deb9u4 (2018-08-21) x86_64 GNU/Linux

I'm trying to install HyperLedger Fabric for which Go is a prerequisite, and clearly go version output shows its successfully installed, however, I'm not sure where or how it needs to be configured to test and use it.

Your GOBIN setting is telling go install to try to install compiled binaries into a system-global directory you don't have permission to write to. Try unsetting that variable; things should default to being installed in $GOPATH/bin.

Also remember that go install takes a package name, not a filename, as its parameter. I'm not clear you can go install something in $GOPATH/src directly, but you can move it into a subdirectory

unset $GOBIN    
cd $GOPATH/src
mkdir github.com/myname/helpp
mv helpp.go github.com/myname/helpp
go install github.com/myname/helpp
$GOPATH/bin/helpp  # uses the name of the package directory
