How to solve class autoloading problem in Yii 1.1?

Question

Yii

Hello. I have the following problem. I unloaded the project on yii1 from the repository, I try to raise it myself, but the following error occurs:
PHP warning
include(FrontController.php): failed to open stream: No such file or directory

If I load this file using includethis class, it is loaded, but falls out error for another file. Do not solve this problem by prescribing includein all files :).
I can't say for sure, but I suspect that the error is due to not configured (or incorrectly configured) class autoloading. Please tell me how to solve the problem?
The config looks like this:

<?php

return array(
    'id' => 'project',
  'modules'=>array(
        'gii'=>array(
            'class'=>'system.gii.GiiModule',
            'password'=>'qwe123',
            'ipFilters'=>array('127.0.0.1','::1'),
            'generatorPaths'=>array(
                'application.gii',
            ),
        ),
    ),	
  'components'=>array(
    'clientScript'=>array(
      'scriptMap'=>array(
        'jquery.js'=>'/lib/jquery/jquery.js',
        'jquery.min.js'=>'/lib/jquery/jquery.min.js',
      ),
    ),
    'fixture'=>array(
      'class'=>'system.test.CDbFixtureManager',
    ),
    /* uncomment the following to provide test database connection
    */
    'db'=>array(
      'connectionString'=>'mysql:host=localhost;dbname=yii_zoton',
      'username'=>'root',
      'password'=>'',
    ),
  ),
);

Thanks in advance to all who respond.
