Here are the steps I took to solve the problem.

1. First make sure your environment version is consistent with the documentation
2. Modify the import

syntax = "proto3";
package validator.examples;
import "validator.proto";
option go_package="./YiuProto";

message InnerMessage {
  // some_integer can only be in range (0, 100).
  int32 some_integer = 1 [(validator.field) = {int_gt: 0, int_lt: 100}];
  // some_float can only be in range (0;1).
  double some_float = 2 [(validator.field) = {float_gte: 0, float_lte: 1}];
}

message OuterMessage {
  // important_string must be a lowercase alpha-numeric of 5 to 30 characters (RE2 syntax).
  string important_string = 1 [(validator.field) = {regex: "^[a-z0-9]{5,30}$"}];
  // proto3 doesn't have `required`, the `msg_exist` enforces presence of InnerMessage.
  InnerMessage inner = 2 [(validator.field) = {msg_exists : true}];
}

3. Execute the correct command line

protoc   \
        -I=F:/GoCode/pkg/mod/github.com/mwitkow/[email protected]/  \
        -I=.  \
        --go_out=.  \
        --go_opt=paths=source_relative  \
        --govalidators_out=.  \
        --govalidators_opt=paths=source_relative  \
        *.proto

Use the -I argument to identify where import needs to be found for protoc compilation.

Actually this error happened on go version: 1.12 too, I just upgraded it to 1.13. So for both of this version this error happens.

Hello @payalord and @liuxuisme.

Thank you for raising the issue!

Would it be possible to get a bit more information about the manner in which you are both invoking the protoc compile? With the information that you currently provide I can't narrow down the list of potential causes of the error that you are seeing. And these potential causes cover a too vast area to explicitly list them up front.

Ideally I would have:

• The folder structure that contains the proto files you are compiling.
• The exact protoc command you are invoking.
• The output of go env when run at the location where you called

  go get -u github.com/golang/protobuf/protoc-gen-go
