go - 为什么不能加载golang/protobuf/proto

Question

const (
    Address = ":50051"
)
func main() {
    listen, err := net.Listen("tcp", Address)
    if err != nil {
        log.Fatalf("failed to listen: %v", err)
    }
    log.Printf("listen on: %s\n", Address)
}

当我运行时:go run main.go我收到此错误:

build command-line-arguments: cannot load github.com/golang/protobuf/proto: module github.com/golang/protobuf/proto: Get https://proxy.golang.org/github.com/golang/protobuf/proto/@v/list: dial tcp 216.58.200.241:443: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established 
connection failed because connected host has failed to respond.

Answer 1

执行以下步骤:

go get github.com/golang/protobuf

go run main.go
