go - “go.etcd.io/etcd/clientv3/balancer/picker”-未定义的: balancer. PickOptions

Question

我在golang中遇到以下错误

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

我试过了

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

有什么办法吗？

Answer 1

您确定您的版本是v1.26.0吗？
您可以分享您的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
一旦您从以下位置更改 go.mod中的版本

google.golang.org/grpc v1.27.0

到

google.golang.org/grpc v1.26.0

您将需要运行以下命令来锁定版本:

go get google.golang.org/grpc@v1.26.0
