framework: php artisan migrate: Cannot redeclare class CreateUsersTable

When i try to:

 php artisan migrate

I get:

PHP Fatal error:  Cannot redeclare class CreateUsersTable in      /database/migrations/2014_10_12_000000_create_users_table.php on line 36

   [Symfony\Component\Debug\Exception\FatalErrorException]
   Cannot redeclare class CreateUsersTable

I already did: sudo composer.phar dump-autoload

Laravel Framework version 5.0.31 I suspect this error is due to permission errors on the autoload.php file

That is happen because this class declared at least 2 times, the first one in laravel/database/migrations/ , and the another one is declared in a non-explicit way by composer as you can see in (/vendor/composer/autoload_classmap.php).

In order to handle this issue, first you have to run : $ composer install

and not that the composer will generate warning look like this:

Warning: Ambiguous class resolution, “CreateUsersTable” was found in both “/var/www/html/laravel1/database/migrations/2015_09_28_082513_create_users_table.php” and “/var/www/html/laravel2/database/migrations/2014_10_12_000000_create_users_table.php”, the first will be used.

This explains why the laravel migration return this collision warning.

@NguyenBaoTran check the database/migrations directory, find out if there is any files containing the same part in file name, XXXX_XX_XX_XXXXXX_create_users_table.php.

If there is, keep only one file that is valid to you.
