Question

在连接中。php 显示错误未定义方法 getDoctrineDriver()。

    public function getDoctrineSchemaManager() {
        return $this->getDoctrineDriver()->getSchemaManager($this->getDoctrineConnection());
    }

    /**
     * Get the Doctrine DBAL database connection instance.
     *
     * @return \Doctrine\DBAL\Connection
     */
    public function getDoctrineConnection() {
        if (is_null($this->doctrineConnection)) {
            $data = ['pdo' => $this->getPdo(), 'dbname' => $this->getConfig('database')];

            $this->doctrineConnection = new DoctrineConnection(
                $data, $this->getDoctrineDriver()
            );
        }
        return $this->doctrineConnection;
    }

.env

    DB_CONNECTION=mysql
    DB_PORT=3306
    DB_DATABASE=mydatabasename
    DB_USERNAME=root
    DB_PASSWORD=

getclass() 在 PHP 8 中已弃用，所以我设法在容器中使用 gettype() 而不是 getclass()。php 接下来运行我的服务器，它显示一个登录页面并在显示此错误后输入用户名和密码我不知道怎么做要解决这个问题！

当更改应用于.env文件时会发生此错误，首先，请确保您的数据库凭据和数据库主机设置正确：

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE="DB NAME"
DB_USERNAME="root"
DB_PASSWORD=""

如果您的问题没有解决，请尝试清除配置缓存：

php artisan config:clear

如果不能解决，请重新启动您的服务器。
