Ratchet: Hello World! tutorial can't find class MyApp/Chat

[Lugia101101]

Heyo,
I have followed every step of the Hello World! tutorial, but can't get past Instantiation. I run it through the command prompt and the following error appears:

php bin\chat-server.php
Fatal error: Class 'MyApp\Chat' not found in C:\path\to\install\betabin\chat-server.php on line 8

File tree and composer.json can be found here: http://pastebin.com/xEDwVBg0
Just wondering if I missed something or interpreted something wrong. Thank you~

Are you including vendor/autoload.php in chat-server.php?

[Lugia101101]

This? require dirname(DIR) . '/vendor/autoload.php'; If so, yes.

[cboden]

Can you post the code to your chat-server.php and Chat.php?

I got the same error..

according to this: http://stackoverflow.com/questions/16868942/ratchet-basic-chat-application-giving-error-failed-opening-required

"php composer.phar update" helped

btw someone should write exactly filestructure to the hello world app, it is not explicitly given where should be chat-server located..
it should be easy to write down:

appfolder/composer.json
appfolder/bin/chat-server.php
appfolder/src/MyApp/Chat.php

btw, i am referring to tutorial from here: http://socketo.me/docs/hello-world

Thank you scholtz, the update command fixed it. I might suggest you add a little note about using the update command after editing composer.json as well.

I'm out of town for four days. When I get back I'll update the website documentation with the recently revised way (composer require cboden/ratchet) to install a package as well as a tree structure.

Thanks a lot. I have the same problem. When I execute php composer.phar update, I fixed it.
