使用ETCD clientv3包,遇到以下错误.
使用了go mod
首先初始化 go mod init
接着go build 出现下面问题
github.com/coreos/etcd/clientv3/balancer/resolver/endpoint
..\..\..\..\pkg\mod\github.com\coreos\[email protected]+incompatible\clientv3\balancer\resolver\endpoint\endpoint.go:114:78: undefined: resolver.BuildOption
..\..\..\..\pkg\mod\github.com\coreos\[email protected]+incompatible\clientv3\balancer\resolver\endpoint\endpoint.go:182:31: undefined: resolver.ResolveNowOption
# github.com/coreos/etcd/clientv3/balancer/picker
..\..\..\..\pkg\mod\github.com\coreos\[email protected]+incompatible\clientv3\balancer\picker\err.go:37:44: undefined: balancer.PickOptions
..\..\..\..\pkg\mod\github.com\coreos\[email protected]+incompatible\clientv3\balancer\picker\roundrobin_balanced.go:55:54: undefined: balancer.PickOptions解决办法
找到go.mod文件
module studygo/day01/67etcd_demo
go 1.13
require (
github.com/coreos/etcd v3.3.18+incompatible // indirect
github.com/coreos/pkg v0.0.0-20180928190104-399ea9e2e55f // indirect
github.com/gogo/protobuf v1.3.1 // indirect
github.com/google/uuid v1.1.1 // indirect
go.etcd.io/etcd v3.3.18+incompatible
go.uber.org/zap v1.14.0 // indirect
google.golang.org/grpc v1.27.1 // indirect
)
将google.golang.org/grpc v1.27.1 // indirect 的版本改成google.golang.org/grpc v1.26.0
//使用go mod download 命令下载
$go mod download
//下载完成后执行go build
$go build
$./xxx.exe //执行文件
//输出结果
./67etcd_demo.exe
connect to etcd success

put to etcd failed, err:context deadline exceeded
//解决办法
1.需要执行文件夹etcd-v3.4.4-windows-amd64下面的etcd.exe
