在Ubuntu 14.04中为Go lang安装protobuf时出现问题

Question

I am following this documentation for installing the golang protobuf on ubuntu 14.04 for go version go1.6 linux/amd64. But it doesn't install the protoc. I am getting an error that protoc is not installed. Also, I have $GOROOT/bin in the path enviroment variable.

Answer 1

The error message is clear to me, you have to install the protoc tool first, it is specified in the documentation: Install the standard C++ implementation of protocol buffers from https://developers.google.com/protocol-buffers/

Also, the error message says the same: on ubuntu system, there is a package containing this binary, which is protobuf-compiler.

The golang protobuf protoc-gen-go is merely a plugin of protoc, that's why you need protoc first.
