使用dep时，如何正确为协议添加golang protobuf/ptypes? [英] How do I correctly include golang protobuf/ptypes for protoc when using dep?

问题描述

我遇到了麻烦，包括 google/protobuf/timestamp.proto 众所周知的类型，当使用 dep 时.

I'm having trouble including the google/protobuf/timestamp.proto well known type, when using dep.

我收到一个错误:google/protobuf/timestamp.proto: File not found

service.proto:

service.proto:

syntax = "proto3";
import "google/protobuf/timestamp.proto";

package com.rynop.platform;
option go_package = "rpc";

service PlatformService {
  rpc Test(EmptyMessage) returns (EmptyMessage);
}

message EmptyMessage { }

message A {  
    string summary = 1;
    google.protobuf.Timestamp start = 2;
}

message B {
  repeated A foos = 1;
}

安装包含时间戳记.proto def的软件包:

Install package containing timestamp .proto def:

dep ensure -add github.com/golang/protobuf/ptypes/timestamp 

运行protoc并得到错误:

build/bin/protoc -Ivendor -I. --twirp_typescript_out=version=v6:./clients/ts-json/ rpc/service.proto
google/protobuf/timestamp.proto: File not found.

包含时间戳的.proto定义的目录存在:

The dir containing timestamp's .proto definition exists:

file vendor/github.com/golang/protobuf/ptypes/timestamp/timestamp.proto
vendor/github.com/golang/protobuf/ptypes/timestamp/timestamp.proto: ASCII text

我要在本地安装协议，因为我不想将协议版本锁定/绑定到该项目:

I'm installing protoc locally because I wan't to lock-in/tie a protoc version to this project:

# fetch the protoc compiler
OS_NAME=$(shell uname -s)
ifeq ($(OS_NAME),Darwin)
    PROTOC_URL=https://github.com/google/protobuf/releases/download/v3.7.1/protoc-3.7.1-osx-x86_64.zip
endif
ifeq ($(OS_NAME),Linux)
    PROTOC_URL=https://github.com/google/protobuf/releases/download/v3.7.1/protoc-3.7.1-linux-x86_64.zip
endif
build/protoc build/bin/protoc:
    mkdir -p build/protoc/bin build/bin
    cd build/protoc && curl -L -o protoc.zip $(PROTOC_URL) && \
        unzip protoc.zip && mv bin/protoc ../bin/protoc

我在做什么错了?

推荐答案

您遇到的protoc错误与您的INCLUDE路径有关.

The protoc error you are getting relates to your INCLUDE path.

安装protoc编译器(例如，安装到/usr/local/bin/protoc)时，要使用它来获取Google的标准原型定义(例如timestamp.proto)，这些定义必须沿着INCLUDE路径添加(在MacOS/Linux上)一个可以使用/usr/local/include).注意:protoc标头应该已经包含在protoc编译器中.

When you installed the protoc compiler (e.g. to /usr/local/bin/protoc), for it to pick up google's standard proto definitions like timestamp.proto - these need to be added somewhere along your INCLUDE path (on MacOS/Linux one may use /usr/local/include). Note: the protoc headers should have been included with the protoc compiler.

因此，原型导入文件通常位于以下位置:

So your proto import file would typically be located here:

/usr/local/include/google/protobuf/timestamp.proto

当protoc编译器看到如下所示的导入时，将引用此路径:

This path will be referenced when the protoc compiler sees an import like:

import "google/protobuf/timestamp.proto";

因此，请检查您的INCLUDE路径，并确保正确安装了protoc标头.

So check your INCLUDE path and ensure the protoc headers are installed correctly.
