How to properly duplicate a working Laravel 4 project - laravel

Question

I have the latest Laravel 4 beta 5 build from Laravel's github repo.
I have built a simple web API and it is working fine. I wanted to duplicate the project to another folder and continue working on it from the copy. However, when I try that, I get the following error message:
InvalidArgumentException
Driver [native] not supported.
/Users/tolga/Sites/l4api-copy/bootstrap/compiled.php
Line 10908: throw new \InvalidArgumentException("Driver [{$driver}] not supported.");
Here is what I did in order to copy the project:
[/Users/tolga/Sites] $ cp -R l4api l4api-copy
[/Users/tolga/Sites] $ chmod -R 755 l4api-copy
It didn't work, so I've tried:
[/Users/tolga/Sites] $ chmod -R 777 l4api-copy/app/storage
Still no good, tried to run composer dump-autoload:
[/Users/tolga/Sites] $ cd l4api-copy
[/Users/tolga/Sites/l4api-copy] $ composer.phar dump-autoload
Generating autoload files
[/Users/tolga/Sites/l4api-copy] $
Same error. I have also tried to remove the app/storage folder and re-create it.
[/Users/tolga/Sites/l4api-copy] $ rm -Rf app/storage
[/Users/tolga/Sites/l4api-copy] $ mkdir app/storage
[/Users/tolga/Sites/l4api-copy] $ chmod -R 777 app/storage/
Here is a brand-new error:
ErrorException
Warning: file_put_contents(/Users/tolga/Sites/l4api-copy/bootstrap/../app/storage/meta/services.json):
failed to open stream: No such file or directory in
/Users/tolga/Sites/l4api-copy/bootstrap/compiled.php line 5507
Line 5507: return file_put_contents($path, $contents);
I have also run composer.phar dump-autoload command again, after emptying the app/storage folder.
And finally, I have also tried composer.phar install:
[/Users/tolga/Sites/l4api-copy] $ composer.phar install
Loading composer repositories with package information
Installing dependencies from lock file
Nothing to install or update
Generating autoload files
[/Users/tolga/Sites/l4api-copy] $
None of the above helped. What am I doing wrong? What is the proper way to duplicate a working project?

Answer 1

After a recent commit to the laravel/laravel repository a new session driver, native, has been introduced. From the looks of your errors you should update your application skeleton (the cloned develop branch of laravel/laravel), delete your bootstrap/compiled.php file and re-run composer update to pull in the latest framework changes.
In terms of copying the project you should copy over everything except the vendor directory then run composer install in the new location. You could copy the vendor directory but it's better to run a clean install and let composer dump a new autoload.
I've also seen Taylor mention a cleanup of your app/storage/sessions directory. Delete all the files in there.
