PDO异常“找不到驱动程序”错误

Question

我是Laravel新手。从最近的两天开始，我正尝试将数据库从laravel迁移到xampp。但是每次我收到PDO异常“找不到驱动程序”错误时。我收到2错误：

1 C:\xampp\htdocs\student\vendor\laravel\framework\src\Illuminate\Database\Connectors\Connector.php:70
      PDOException::("could not find driver")

  2   C:\xampp\htdocs\student\vendor\laravel\framework\src\Illuminate\Database\Connectors\Connector.php:70
      PDO::__construct("mysql:host=127.0.0.1;port=3306;dbname=student", "root", "", [])


could not find driver (SQL: select * from information_schema.tables where table_schema = student and table_name = migrations and table_type = 'BASE TABLE')

我在stackoverflow和许多其他网站上进行了搜索，并获得了许多解决方案，但它不适用于我。我仍然遇到这些错误。我还添加了我从多个stackoverflow解决方案中获得的所有必需扩展。但仍然无法正常工作。我随便附上代码。谁能帮助我找到我做错了什么？在此先感谢！

            $table->string('email');
            $table->string('class');
            $table->int('pnumber');
            $table->timestamps();

在Ubuntu / Debian中，您可以使用：

PHP5: sudo apt-get install php5-mysql
PHP7: sudo apt-get install php7.0-mysql

在Windows中转到php.ini，然后从这些行中将其删除：

extension=php_pdo.dll
extension=php_pdo_mysql.dll
OR:

extension=pdo.dll
extension=pdo_mysql.dll
