anyone else having issues running “ionic serve” on 10.9.4? using this command “npm install -g cordova ionic” everything seemed to install correctly so when i run the “ionic serve” command it come up with an error:

TypeError: Object function createServer() {
function app(req, res, next){ app.handle(req, res, next); }
merge(app, proto);
merge(app, EventEmitter.prototype);
app.route = ‘/’;
app.stack = [];
return app;
} has no method 'static’
