# error: could not import "google/protobuf/timestamp.proto": file not found

- **ID:** `go/grpc-missing-proto-import`
- **Domain:** go
- **Category:** build_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

The .proto file imports a dependency that is not in the protoc include path, causing compilation to fail.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| 1.9 | active | — | — |

## Workarounds

1. **Add the protobuf include path to protoc** (90% success)
   ```
   protoc -I=. -I=/usr/include your.proto
   ```
2. **Use a dependency manager like Buf** (85% success)
   ```
   buf generate
   ```

## Dead Ends

- **Copy the timestamp.proto file into the same directory** — It may conflict with the system-wide protobuf installation and cause version mismatches. (50% fail)
- **Remove the import and use a custom timestamp field** — This changes the API and may break compatibility. (60% fail)
