go语言版本

go version
go version go1.14 linux/amd64

经过测试，在macOS，Windows，Linux上都有这个问题

添加包管理器go mod

module goAgent
go 1.14

require (
    github.com/Shopify/sarama v1.26.1
    github.com/coreos/etcd v3.3.18+incompatible // indirect

主要错误原因： 在安装go get go.etcd.io/etcd/clientv3时出错

错误信息：

# github.com/coreos/etcd/clientv3/balancer/resolver/endpoint

../../pkg/mod/github.com/coreos/etcd@v3.3.18+incompatible/clientv3/balancer/picker/roundrobin_balanced.go:55:54: undefined: balancer.PickOptions

解决方法

将grpc版本替换成v1.26.0版本

具体步骤

修改依赖为v1.26.0

go mod edit -require=google.golang.org/grpc@v1.26.0

下载v1.26.0版本的grpc

go get -u -x google.golang.org/grpc@v1.26.0

重新构建运行程序

go build

大功告成！
