PDO例外仅适用于Laravel中的PostgreSQL连接，但手工命令有效

我是laravel的新手。我刚刚从mysql迁移到postgresql，并成功地手工迁移了我所有的表，并通过修补程序对它们进行了种子处理。然而，我所有使用mysql和SQL查询的样板文件laravel-auth的尝试都在返回。

PDOException in Connector.php line 55:
could not find driver in Connector.php line 55
at PDO->__construct('pgsql:host=localhost;dbname=dbname;port=5432','postgres', 'password', array('0', '2', '0', false)) in Connector.php line 55

我花了几个小时寻找这个问题的解决方案，我已经取消了extension=php_pgsql.dll&extension=php_pdo_pgsql.dll，在生产和开发php.ini文件中，我已经将LoadFile"c:''mamp/bin/php/php5.6.13/libpq.dll"添加到Apache文件夹中的hhtp.conf中，我有composer dump自动加载。laravel的查询没有像migrate命令那样显示在postgres错误日志中。我不记得我是如何检查的，但PDO模块似乎安装了

我的数据库.php

'default' => env('DB_CONNECTION', 'pgsql'), 
 'pgsql' => [
        'driver' => 'pgsql',
        'host' => env('DB_HOST', 'localhost'),
        'port' => env('DB_PORT', '5432'),
        'database' => env('DB_DATABASE', 'forge'),
        'username' => env('DB_USERNAME', 'forge'),
        'password' => env('DB_PASSWORD', ''),
        'charset' => 'utf8',
        'prefix' => '',
        'schema' => 'public',
    ],

我的env

APP_URL=http://localhost
DB_HOST=localhost
DB_DATABASE=database
DB_USERNAME=postgres
DB_PASSWORD=password
APP_ENV=local
APP_DEBUG=true
CACHE_DRIVER=file
SESSION_DRIVER=file
 QUEUE_DRIVER=sync
 REDIS_HOST=127.0.0.1
 REDIS_PASSWORD=null
 REDIS_PORT=6379
 MAIL_DRIVER=smtp
  MAIL_HOST=mailtrap.io
 MAIL_PORT=2525
 MAIL_USERNAME=null
 MAIL_PASSWORD=null
 MAIL_ENCRYPTION=null

请上帝给我一个答案
