Validating non empty fields Node and Passport

I need to validate non empty fields before post login, but I get this error:

TypeError: req.checkBody is not a function
    at D:\IDoo projects\ExpressGenerado\config\routes.js:76:9

This is my route file:

  app.post('/login',function(req,res){
    req.checkBody('email', 'Email is required').notEmpty();
    req.checkBody('password', 'Password is required').notEmpty();
    var errors = req.validationErrors();

    if (errors) {

        res.render('signup',{message: req.flash('loginMessage')});

    }
    else{
        passport.authenticate('local-login', {
            successRedirect : '/profile', // redirect to the secure profile section
            failureRedirect : '/login', // redirect back to the signup page if there is an error
            failureFlash : true // allow flash messages
        })(req,res); 
    }
});
