使用的是哪个版本的Windows系统？Windows系统下创建软连接会优先调用mklink这个外部命令。我身边没有Windows设备，无法去验证，你手动调用 mklink 试着创建下软连接，一起排查下。

func mkSymlink(oldname, newname string) (err error) {
	if runtime.GOOS == "windows" {
		// Windows 10下无特权用户无法创建符号链接，优先调用mklink /j创建'目录联接'
		if err = exec.Command("cmd", "/c", "mklink", "/j", newname, oldname).Run(); err == nil {
			return nil
		}
	}
	return os.Symlink(oldname, newname)
}

碰到类似问题 已解决，可以先看看g.exe所在目录有没有go文件夹的快捷方式图标，如果没有就看看你登录用户（一般是C:\Users\你本地的用户名\.g）有没有go目录，有的话设置GOROOT=C:\Users\你本地的用户名\.g\go
