golang环境变量存储在哪里？

Question

I am just started learning golang on Windows 7.

With go env, I got this:

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

Then I checked with echo %envVar% in the command line, I found env vars like:

GOPATH
GOROOT

But others are not found.

So where are they stored? Some hidden configuration file?

Answer 1

Those are just the defaults for your platform. Think of them as stored in the go.exe executable itself.

You can override them by setting them to something else like any other env var.
