Cannot GET / error

I keep getting the Cannot GET / error. also on the end of the video when i included the public folder with app.use('/', express.static('public'));

I've the same in the video I also copied and paste it into my code without any success.

'use strict';

var express = require('express');

var app = express();

app.use('/', express.static('public'));

app.listen(3000, function() { console.log("The server is running on port 3000!"); });

The video instruction was unclear about this part.

This worked for me :

app.use('/', express.static('public/public'));

the above solution worked if you cloned the mean-todo repo in the notes as suggested.

https://github.com/treehouse-projects/mean-todo

The correct way is to clone the angular-basics repo below...

git clone https://github.com/treehouse/angular-basics .

If you cloned the mean-todo repo first like I did. In order to setup the correct repo, run these commands:

rm -rf public

m -rf .git

mkdir public

cd public

git clone https://github.com/treehouse/angular-basics .

I fixed it whit added ../ before the public

I am having the same problem but adding ../ didn't seem to help. I've also tried it the way it is written in the video as well and still no luck:

'use strict'

var express = require('express');

var app = express();

app.use('/', express.static('../public'));

app.listen(3000, function() {
  console.log("The server is running.");
});

This actually fixed my issue.

lastly, direct express to the proper directory:

app.use('/', express.static('public'));

Hope that helps!

It worked for me! Tks... but i dont like to do without know whats happening...

I don't know if this will help anyone else or not, but i was having the same problem & couldn't figure it out from watching the video again or based on the comments here. My directories seemed to be set up correctly but i was still getting CANNOT GET when running the app in my browser.

I removed the first parameter - the '/' - in the app.use(); method, then stopped my server & restarted it, refreshed the browser & i'm good to go.

So it ended up looking like app.use(express.static('public'));

Hope that helps someone :)

Worked for me, thanks. Removing the '/' in the app.use(); method AND restarting the server works. Didn't work without restarting the Server!

if you're cloning your own forked repo, the clone will unpackage the whole app, not just the public folder. You want only the public folder from the forked repo unpackaged in your public folder, which isn't super clear in the video.

Well I've spent 11 hours straight on a 9:53 minute video and still can't get any of this to work. That's right I started just after midnight and its 11:15 am now. Literally everything on this video is broken. I'm like 2 inches from pulling the plug on my treehouse subscription and trying out Lynda...This type of careless teaching is exasperating.

My brain just feels like swiss cheese and I couldn't even setup the bloody environment in 11 hours. Insane. Just insane.
