我是 Go 和 Protobufs 的新手，因此这可能是一个非常菜鸟的问题。对此感到抱歉。
我的 go 项目中有几个包，我想创建一个单独的包，其中包含我所有的 .proto（也是 .pb.go）文件，然后我可以将这些 proto 文件导入任何其他包中，以更好地管理我的所有 proto 文件。
但是当我将我的 proto 文件移动到一个名为“prototemps”的单独包中并将“prototemps”导入另一个名为“reader”的包中时。在 reader.go 中，我这样做：
sensorData := &prototemps.Sensor{}
err := proto.Unmarshal(msg.Payload(), sensorData)
它产生这个错误
var sensorData *prototemps.Sensor
cannot use sensorData (variable of type *prototemps.Sensor) as protoreflect.ProtoMessage value in argument to proto.Unmarshal: missing method ProtoReflect
这是我的项目结构的样子：
ProjectFolder/
/prototemps/<all .proto and .pb.go exist here> (Package "prototemps")
/reader/reader.go which fails when tries to do proto.Unmarshall (Package "reader")
这是我的 .proto 的样子
syntax="proto3";
package prototemps;
import "google/protobuf/timestamp.proto";
message sensor {
string Name = 1;
int32 ID = 2;
string Type = 3;
orientation Ori = 4;
IO IO = 5;
google.protobuf.Timestamp ts = 6;
}
message orientation {
int32 X = 1;
int32 Y = 2;
int32 Z = 3;
}
message IO {
int32 Reads = 1;
int32 Writes = 2;
}
这是我使用 * protoc --go_out= 生成的 .pb.go。.proto
