Golang - google/protobuf/Empty.proto: File not found

问题

以下是翻译好的内容:

syntax = "proto3";

package model;

import "google/protobuf/Empty.proto";

message User {
    string id = 1;
    string name  = 2;
    string email = 3;
    string alamat = 4;
    string password = 5;
}

message UserList {
    repeated User list = 1;
}

message userId {
    string id = 1; 
}

message UserUpdate {
    string id = 1;
    User user = 2;
}

service Users {
    rpc getUserList(google.protobuf.Empty) returns (UserList) {}
    rpc getUserById(userId) returns (User) {}
    rpc inserUser(User) returns (google.protobuf.Empty) {}
    rpc updateUser(UserUpdate) returns (google.protobuf.Empty) {} 
    rpc deleteUser(userId) returns (google.protobuf.Empty) {}  
}

以上是我的proto文件。当尝试编译上述proto文件时,出现了"google/protobuf/Empty.proto: File not found"的错误。有人可以帮我吗?

英文:
syntax = "proto3";

package model;

import "google/protobuf/Empty.proto";

message User {
    string id = 1;
    string name  = 2;
    string email = 3;
    string alamat = 4;
    string password = 5;
}

message UserList {
    repeated User list = 1;
}

message userId {
    string id = 1; 
}

message UserUpdate {
    string id = 1;
    User user = 2;
}

service Users {
    rpc getUserList(google.protobuf.Empty) returns (UserList) {}
    rpc getUserById(userId) returns (User) {}
    rpc inserUser(User) returns (google.protobuf.Empty) {}
    rpc updateUser(UserUpdate) returns (google.protobuf.Empty) {} 
    rpc deleteUser(userId) returns (google.protobuf.Empty) {}  
}

above is my proto file. I get error google/protobuf/Empty.proto: File not found.
when trying to compile the proto file above. can someone help me ?

首先,正确的导入语句是 import "google/protobuf/empty.proto";

其次,要生成一个 proto 文件,请运行以下代码:

protoc --proto_path={proto_directory_address} --proto_path={proto_directory_name} --go-grpc_out={generated_directory_path} --go_out={generated_directory_path} {proto_directory_address}/{proto_file_name}.proto

英文:

First of all, the correct import is import "google/protobuf/empty.proto";

second, for generating a proto file run this code:

protoc --proto_path={proto_directory_address} --proto_path={proto_directory_name} --go-grpc_out={generated_directory_path} --go_out={generated_directory_path} {proto_directory_address}/{proto_file_name}.proto

嗨,我知道你遇到了同样的问题很长一段时间了。这个方法对我有效,希望对你也有效:

使用命令行导航到以下目录:

cd .local/include

这个目录通常应该包含一个名为"google"的文件夹,将该文件夹复制并粘贴到以下目录:

/usr/local/include

然后再次尝试使用protoc引擎生成你的项目,如果错误仍然存在,那么尝试以下步骤:

导航到特定的目录,检查是否已经复制过。如果已经复制过,尝试从你所在的文件夹导航到该文件夹(应该是/usr/local/include),如果错误提示你没有权限进入该文件夹,使用以下命令获取权限:

$ sudo chmod o+r -R ./google

然后再次使用上述命令获取相同目录中protobuf文件夹的权限。

完成所有步骤后,再次检查protoc生成器。希望对你有帮助,因为对我有效。

英文:

hi there / i had the same issue for a long time .. this process worked for me i hope it dose for you too :
navigate to this directory using your cmd(command line) :

> cd .local/include

this directory normally should contain some folder named "google" copy this folder and paste it to this directory :

> /usr/local/include

and now try the protoc engine again to generate your project and if the error still exists then try the rest of process :

navigate to that specific directory and check if its been copied or not . if it is then try to navigate to the folder from where you are (which it should be /usr/local/include) if the error says you have no permission to get in the folder
use this command to get the permission

> $ sudo chmod o+r -R ./google

and then try to get permission to get in protobuf folder in the same directory using above command again
when its all done . check the protoc generator again /// hope works for you because it dose for me

我遇到了同样的问题,因为我没有正确安装 protoc。

要成功安装,请按照以下步骤进行操作:

  1. 从这里下载最新版本 https://github.com/protocolbuffers/protobuf/releases
  2. 在你的计算机上解压缩
  3. 将 bin/protoc 移动到 /usr/local/bin
sudo mv {下载的目录}/bin/protoc /usr/local/bin
  1. 将 include 文件夹移动到 /usr/local
sudo mv {下载的目录}/include /usr/local
英文:

I had the same problem because I had not installed the protoc correctly

For successful installation do these steps:

  1. Download latest version from here https://github.com/protocolbuffers/protobuf/releases
  2. Extract in your computer
  3. move bin/protoc to /usr/local/bin
sudo mv {downloaded_directory}/bin/protoc /usr/local/bin
  1. move include folder to /usr/local
sudo mv {downloaded_directory}/include /usr/local

导入公共库 "google/protobuf/empty.proto"。

英文:

import public "google/protobuf/empty.proto";
