根因分析

protoc 在 PATH 上找不到 protoc-gen-go 插件二进制。它通过 go install 安装，但 $GOPATH/bin 未加入 PATH，或二进制名称不对。

English

protoc cannot locate the protoc-gen-go plugin binary on PATH. It is installed via go install but $GOPATH/bin is not on PATH, or the binary name is wrong.

解决方案

  1. 95% 成功率 
    go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
export PATH="$PATH:$(go env GOPATH)/bin"
which protoc-gen-go
  2. 90% 成功率 
    protoc --plugin=protoc-gen-go=$(go env GOPATH)/bin/protoc-gen-go \
  --go_out=. user.proto

无效尝试

常见但无效的做法:

  1. 80% 失败

    The error is about the Go plugin, not the protoc compiler. Reinstalling protoc does not add protoc-gen-go to PATH.

  2. 75% 失败

    protoc resolves plugins by name on PATH; passing a binary path as an output directory is invalid.
