./protoc-gen-go很慢吗？

Question

I am trying to compile a .proto file to generate code. Does it last much time to compile or am I doing something wrong? Compilation seems to be endless

Answer 1

Compiling a protobuf file should last a few seconds at most.

But it sounds like you are invoking protoc-gen-go directly. It is designed to be used as a plugin to protoc, so you should use:

protoc --go_out=. msg.proto

If it cannot find the generator binary because it's not in your path, you'll also need to specify --plugin=protoc-gen-go=/path/to/protoc-gen-go.

When used stand alone, protoc-gen-go will be waiting for input on stdin, and will display error message once you terminate it with ctrl-D.
