GoLang gRPC项目引入protoc-gen-openapiv2依赖报错求助

我在基于GoLang+gRPC的技术栈中给proto文件添加分页功能，引入了以下依赖：

import "google/api/annotations.proto";
import "protoc-gen-openapiv2/options/annotations.proto";
import "google/protobuf/timestamp.proto";

尝试通过go install或go get安装这些依赖时，分别出现如下报错：

使用go install时的报错 #

go install protoc-gen-openapiv2/options/annotations.proto@latest                                                        
go: protoc-gen-openapiv2/options/annotations.proto@latest: malformed module path "protoc-gen-openapiv2/options/annotations.proto": missing dot in first path element

使用go get时的报错 #

go get protoc-gen-openapiv2/options/annotations.proto                                                                 
go: go.mod file not found in current directory or any parent directory.
        'go get' is no longer supported outside a module.

我已经查阅过grpc-gateway的官方文档，确认操作流程无误，但仍遇到该问题。想问问有没有其他人遇到过类似的情况？

我的相关proto消息定义如下：

message BlogAllRequest {
    option (grpc.gateway.protoc_gen_openapiv2.options.openapiv2_schema) = {
        json_schema: {
            required: ["filter"]
        }
    };

    string id = 1;
    int32 page = 2;
    int32 per_page = 3 [json_name="per_page"];
    SortOrder order = 4 [json_name = "order"];

}
