Laravel类包括路径

Question

I want to create a BaseMigration class like in this tutorial. I've saved it as app/database/migrations/BaseMigration.php and extend it in my other migrations, but when I try to run my migrations via php artisan migrate I get the following error:

PHP Fatal error: Class 'BaseMigration' not found in ...\app\database\migrations\2014_02_19_071702_create_users_table.php on line 6

Obviously it's having trouble autoloading it. How do I tell Laravel where to find it, or where should I move it to so that it can be found?

Answer 1

Usually

composer dump-autoload

Fixes those kind of errors, but sometimes it doesn't.

To understand if the problem is not in Laravel, but in autoloading (Composer or even PHP), take a look a the files in

vendor/composer/*

If your file is not using PSR-0, PSR-4 nor file autoloading, it should be

vendor/composer/autoload_classmap.php

If your file class is listed there, the problem is in your code, you're referencing it wrongly. In those files you'll find also the way you have to reference to it, for instance, if you have a namespace set on it, you'll have to use it the way it appears on those files.

If it's not listed, the problem is in the guy responsible for autoloading things: Composer (maybe even PHP) and you can refresh it to try to fix it:

 rm -rf vendor
 rm composer.lock
 composer install
