How do I import annotations into proto?
问题
我正在尝试将注释导入到我的proto文件中。我将"google"文件夹复制到"project/proto/google"目录下。
import "google/api/annotations.proto";
路径google/api/annotations.proto是项目所在的位置。我尝试使用go mode init和vendor，但没有帮助。
在proto文件中，只有google/protobuf提供自动完成，我在GOPATH中没有看到这样的文件夹。
我该怎么做才能使其工作？
编辑1-
我使用以下命令：
protoc -I $GOPATH/src/github.com/jeka2708/test-grpc/proto/ --go_out=. --go_opt=paths=source_relative --go-grpc_out=. --go-grpc_opt=paths=source_relative proto/login.proto
英文:
I am trying to import annotations into my proto file. I copied the "google" folder to "project / proto/google".
import "google/api/annotations.proto";
the path google / api / annotations.proto - the project is located.
I am tried use the go mode init and vendor, it didn`t help
In the proto file, only google/protobuf offers autocomplete and that's it, I don't see such a folder in GOPATH
What do I do to make it work?

I use
protoc -I $GOPATH/src/github.com/jeka2708/test-grpc/proto/ --go_out=. --go_opt=paths=source_relative --go-grpc_out=. --go-grpc_opt=paths=source_relative proto/login.proto

google/api/annotations.proto不是protoc编译器分发的基本标准包含文件的一部分（请参见最新版本此处）。
要将其纳入protoc构建中，只需下载所需版本（最新版本），还需要其包含的依赖项http.proto），并将其放置在后缀与导入路径匹配的目录中，例如：
/SOME/DIRECTORY/PATH/google/api/annotations.proto
/SOME/DIRECTORY/PATH/google/api/http.proto
前缀路径可以是系统默认的包含路径（例如/usr/include），例如：
/usr/include/google/api/annotations.proto
/usr/include/google/api/http.proto
或者您可以将其放置在某个项目目录中：
/home/user/my_proj/google/api/annotations.proto
/home/user/my_proj/google/api/http.proto
protoc编译器将默认查找当前工作目录，或者您可以通过命令行选项指定自定义包含路径：
Usage: ./protoc [OPTION] PROTO_FILES
解析PROTO_FILES并根据给定的选项生成输出：
-IPATH, --proto_path=PATH 指定要搜索导入的目录。可以多次指定；将按顺序搜索目录。如果未指定，则使用当前工作目录。如果在这些目录中找不到，则将检查--descriptor_set_in描述符是否需要proto文件。
英文:
google/api/annotations.proto is not part of the base standard of include files that comes with the protoc compiler distribution (see latest here).
To incorporate it in your protoc build - simply download the version you need (latest, you'll also need it's included dependency http.proto) - and place it in a directory who's suffix matches the import path i.e.
/SOME/DIRECTORY/PATH/google/api/annotations.proto
/SOME/DIRECTORY/PATH/google/api/http.proto
The prefix path could be the system default include path (/usr/include) e.g.
/usr/include/google/api/annotations.proto
/usr/include/google/api/http.proto
or you can place in some project directory:
/home/user/my_proj/google/api/annotations.proto
/home/user/my_proj/google/api/http.proto
and the protoc compiler will default to looking in the current working directory - or you can specify custom include paths via the command-line options:
Usage: ./protoc [OPTION] PROTO_FILES
Parse PROTO_FILES and generate output based on the options given:
-IPATH, --proto_path=PATH Specify the directory in which to search for
imports. May be specified multiple times;
directories will be searched in order. If not
given, the current working directory is used.
If not found in any of the these directories,
the --descriptor_set_in descriptors will be
checked for required proto file.
