[voltairemakeit]

Hi,

Keystonejs (yo generator) is working perfectly.

When I try to install sydjs
I get the following error when I run node keystone.js :

undefined is not a function

Middleware.js

**
 Fetches and clears the flashMessages before a view is rendered
*/


exports.flashMessages = function(req, res, next) {
 var flashMessages = {
 info: req.flash('info'),
 success: req.flash('success'),
 warning: req.flash('warning'),
 error: req.flash('error')
 };
 res.locals.messages = _.any(flashMessages, function(msgs) { return msgs.length }) ? flashMessages : false;
 next();
};

I tried with async@1.4 and the last stable

node v0.12.4

npm 2.10.1

MongoDB 3.2.7
