Go looks for packages in wrong directory

I've used the Windows msi to install Go on my machine, but when I try to run a trivial Hello World, like so:

go run hello.go

I get the following error:

hello.go:3:8: cannot find package "fmt" in any of: C:\Go\src\pkg\fmt (from $GOROOT)

In the GOROOT this package can indeed not be found, since it's installed in the following directory:

C:\Go\src (missing the \pkg)

GOROOT is set to C:\Go (automatically), C\Go\bin is added to the PATH

My GOPATH is set to my workspace, but that doesn't seem to change anything.

How can this be fixed? Should I copy all packages to C:\Go\src\pkg? Did I do anything wrong?

EDIT

As requested by @Volker, here's the output of go env:

set GOARCH=amd64
set GOBIN=
set GOCHAR=6
set GOEXE=.exe
set GOHOSTARCH=amd64
set GOHOSTOS=windows
set GOOS=windows
set GOPATH=D:\aage\gocode
set GORACE=
set GOROOT=C:\Go
set GOTOOLDIR=C:\Go\pkg\tool\windows_amd64
set CC=gcc
set GOGCCFLAGS=-m64 -mthreads -fmessage-length=0
set CXX=g++
set CGO_ENABLED=1

Check your %PATH%: I have multiple go versions installed and I see:

  • fmt in %GOROOT%(1.3)\src\pkg: C:\prgs\go\go1.3.2.windows-amd64\src\pkg\fmt\
  • fmt in %GOROOT%(1.4)\src: C:\prgs\go\go1.4.windows-amd64\src\fmt\

The sources have been reorganized.
See "Go 1.4 src/pkg → src".

That means you might see that error if you are trying to compile with a go 1.3 while GOROOT points to a Go1.4 installation.

If that doesn't work, uninstall, and use the go1.4.windows-amd64.zip archive: unzip it anywhere you want, point GOROOT to it, add GOROOT/bin and everything should work.
