无法导入原始文件

我花了数小时试图阅读有关如何在Golang中使用简单原型文件的博客。我生成了.pb.go文件。所有互联网示例都充斥着从某些随机"github...URL进行导入以进行原型导入的麻烦。我找不到任何有关如何导入与我的.go文件或diff目录相同目录的简单原型文件的示例。如何使用本地文件系统中的原始文件。

go build hello.go
hello.go:5:2: cannot find package "customer" in any of:
    /usr/local/go/src/customer (from $GOROOT)
    /Users/myhomedir/go/src/customer (from $GOPATH)

的Contentes hello.go在$ SOME_DIR /客户

package main

import  (
    "fmt"
    pb "customer"
)

func main() {
    fmt.Println("hello test message\n")
}

内容 customer.proto

syntax = "proto3";
package customer;


// The Customer service definition.
service Customer {
  // Get all Customers with filter - A server-to-client streaming RPC.
  rpc GetCustomers(CustomerFilter) returns (stream CustomerRequest) {}
  // Create a new Customer - A simple RPC
  rpc CreateCustomer (CustomerRequest) returns (CustomerResponse) {}
}

// Request message for creating a new customer
message CustomerRequest {
  int32 id = 1;  // Unique ID number for a Customer.
  string name = 2;
  string email = 3;
  string phone= 4;

  message Address {
    string street = 1;
    string city = 2;
    string state = 3;
    string zip = 4;
    bool isShippingAddress = 5;
  }

  repeated Address addresses = 5;
}

message CustomerResponse {
  int32 id = 1;
  bool success = 2;
}
message CustomerFilter {
  string keyword = 1;
}
