go - "go.etcd.io/etcd/clientv3/balancer/picker"- 未定义 : balancer. PickOptions

Question

我在 golang 中遇到以下错误

# go.etcd.io/etcd/clientv3/balancer/picker

/home/user/go/src/go.etcd.io/etcd/clientv3/balancer/resolver/endpoint/endpoint.go:183:31:

我已经尝试过

go get -u google.golang.org/grpc

但仍然遇到同样的问题。我的grpc版本是v1.26.0

有什么解决办法吗？

Answer 1

您确定您的版本是v1.26.0吗？ 您能分享一下您的go.mod吗？

go get -u google.golang.org/grpc

上面的命令是检索 grpc 的最新版本，即 v1.27.1

一旦您更改了 go.mod 中的版本

google.golang.org/grpc v1.27.0

至

google.golang.org/grpc v1.26.0

您需要运行以下命令来锁定版本:
