Root Cause

The same .proto file is being imported and registered multiple times, often due to circular imports or duplicate imports.

generic

中文

同一个 .proto 文件被多次导入和注册，通常是由于循环导入或重复导入。

Workarounds

  1. 90% success 
    Ensure each .proto file is imported only once in the dependency graph; use go module to manage dependencies.
  2. 85% success 
    Use protoc with --go_opt=paths=source_relative to avoid duplicate registration.

Dead Ends

Common approaches that don't work:

  1. 70% fail
