cannot find module 'passport-local' error

Question

am using passport in node.js

in my app.js

var passport = require('passport')

require('./config/passport').boot(passport, config)

in passport.js

var LocalStrategy = require('passport-local').Strategy

run the app and i get this error message

module.js:340
    throw err;

error:Cannot find module 'passport-local'
      at Object.<anonymous> <F:\work\config\passport.js:2:21>

i install the passport in F:\work\node_modules.

even if i put the

 var LocalStrategy = require('passport-local').Strategy

right under the

 var passport = require('passport')

i still get the same error

any idea why?

Answer 1

I had the same problem and I solved it:

Check your package.json file. If it does not exist, you need to init your project in the same folder where you wrote your main JS file (server.js or index.js or however you want).

$ sudo npm init 

and when installing npm modules, remeber to save them in package file:

$ sudo npm install passport-local --save 

I solved in this way.
