Windows – GOPATH value setting

gowindows

I'm install the go with the go1.3.1.windows-amd64.msi, after installation GOROOT is default setting, I found the
D:\Programs\Go\bin in the PATH,then I create a GOPATH environment variant,
when using the 'go get' command, error occurs:

package github.com/coreos/etcd: cannot download, $GOPATH must not be set to $GOROOT. For more details see: go help gopath

OS: windows 7

GOPATH will conflict with GOROOT?

How can I set these two PATH values?

Best Answer

  • GOROOT must reference the folder where you installed GO
  • GOPATH must reference an empty folder which will be your workspace (src/pkg/bin for your projects)

Add those two variables in your user environment variables.

A go get github.com/coreos/etcd should:

  • download the sources in %GOPATH%/src/github.com/coreos/etcd (src is created for you)
  • compile it in %GOPATH%/pkg/windows_amd64 (pkg/ is created for you, windows_amd64 reflects your windows architecture)
  • with go install, install it in %GOPATH%/bin (bin/ is also created for you)

Note: with Go 1.8+ (Q2 2017), GOPATH might be set for you by default to (on Windows) %USERPROFILE%/go.
On Linux, it would be $HOME/go: see issue 17262.

Update 2018, three years later: GOPATH is becoming obsolete with Go 1.11 modules:

mkdir newProject
cd newProject
set GO111MODULE=on
go mod init myproject
