建了个demo来测试Bazel构建golang项目，项目位于D:\workspace\www\go_work\src\golang_learning，有以下文件：

golang_learning
  |__ go.mod
  |__ main.go
  |__ WORKSPACE
  |__ BUILD.bazel

各文件内容如下，Bazel的两个文件WORKSPACE和BUILD.bazel按照文档来写的https://github.com/bazelbuild...
go.mod

module golang_learning

main.go

package main

import "fmt"

func main() {
    fmt.Println("Hello,world")
}

WORKSPACE

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
http_archive(
    name = "io_bazel_rules_go",
    urls = ["https://github.com/bazelbuild/rules_go/releases/download/0.16.1/rules_go-0.16.1.tar.gz"],
    sha256 = "f5127a8f911468cd0b2d7a141f17253db81177523e4429796e14d429f5444f5f",
)
http_archive(
    name = "bazel_gazelle",
    urls = ["https://github.com/bazelbuild/bazel-gazelle/releases/download/0.15.0/bazel-gazelle-0.15.0.tar.gz"],
    sha256 = "6e875ab4b6bf64a38c352887760f21203ab054676d9c1b274963907e0768740d",
)
load("@io_bazel_rules_go//go:def.bzl", "go_rules_dependencies", "go_register_toolchains")
go_rules_dependencies()
go_register_toolchains()
load("@bazel_gazelle//:deps.bzl", "gazelle_dependencies")
gazelle_dependencies()

BUILD.bazel

load("@bazel_gazelle//:def.bzl", "gazelle")

# gazelle:prefix github.com/example/project
gazelle(name = "gazelle")

当运行 bazel run //:gazelle的时候，出现如下错误：

PS D:\workspace\www\go_work\src\golang_learning> bazel run //:gazelle

是哪里没有配置正确？
