处理etcd源码包编译异常-编程知识

1、下载etcd包，执行go build报异常：

client\v2\example_keys_test.go:1:1: expected 'package', found '.'
client\v3\example_auth_test.go:1:1: expected 'package', found '.'
client\v3\concurrency\example_election_test.go:1:1: expected 'package', found '.'

2、尝试解决方案：

我照网上的解决方案去处理，处理完之后报另外一个错误：

replace google.golang.org/grpc => google.golang.org/grpc v1.26.0
//在主目录下执行go.mod的replace下添加最后一行：
replace (go.etcd.io/etcd/api/v3 => ./apigo.etcd.io/etcd/client/pkg/v3 => ./client/pkggo.etcd.io/etcd/client/v2 => ./client/v2go.etcd.io/etcd/client/v3 => ./client/v3go.etcd.io/etcd/etcdctl/v3 => ./etcdctlgo.etcd.io/etcd/etcdutl/v3 => ./etcdutlgo.etcd.io/etcd/pkg/v3 => ./pkggo.etcd.io/etcd/raft/v3 => ./raftgo.etcd.io/etcd/server/v3 => ./servergo.etcd.io/etcd/tests/v3 => ./testsgoogle.golang.org/grpc => google.golang.org/grpc v1.26.0
)

之后会报执行go build后报：

这个错误提示说明在你的项目中，有一个 `go.etcd.io/etcd/tests/v3/integration` 包导入了 `google.golang.org/grpc`，但是在你的 `go.sum` 文件中缺少了与 `google.golang.org/grpc` 相关的模块条目
go get google.golang.org/grpc@v1.26.0

之后又报，最后又提示我这个，搜了一圈之后，说是我的grpc的版本不包含当前的某个包，也就是转来转去又转回去了：
