Error: Cannot find module 'google-protobuf'

问题

Following to my previous question, I'm trying to use protocol buffers in node.js. I've generated ServiceMessage_pb.js from my ServiceMessage.proto, and add the following code:

var messages = require('./ServiceMessage_pb');

Now I'm getting the following error in my node log:

Error: Cannot find module 'google-protobuf'
    at Function.Module._resolveFilename (module.js:325:15)
    at Function.Module._load (module.js:276:25)
    at Module.require (module.js:353:17)
    at require (internal/module.js:12:17)
    at Object.<anonymous> (/home/aii/ws/ServiceMessage_pb.js:8:12)

    at Module.load (module.js:343:32)
    at Function.Module._load (module.js:300:12)
    at Module.require (module.js:353:17)

Any suggestions how to solve this?

Thanks

回答1:

You can install the module with npm:

npm install --save protobuf

Then require it this way:

var my_protobuff = require ("protobuf");

回答2:

    npm i google-protobuf

I run into so many problem installing just "protobuf" !

Also the official protobuf javascript package is "google-protobuf": https://www.npmjs.com/package/google-protobuf
