PHP Symfony 服务器 - “驱动程序发生异常：找不到驱动程序”

Question

我使用终端命令symfony serve启动名为“test2”的 Symfony 应用程序（我也尝试过symfony server:start ），但出现错误：

处理异常时抛出异常 (Doctrine\DBAL\Exception\DriverException: An exception occurred in driver: could not find driver at /var/www/html/test2/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/AbstractPostgreSQLDriver .php 线 102)

我正在使用 Ubuntu 20.04、PHP 7.4、Symfony CLI 4.25，如果需要的话，Composer 205。

我也在使用 PostgreSQL，我运行了sudo apt-get install php-pgsql 。

我也检查了“php.ini”，这是一个截图：

这是突出显示错误的整个响应：

有人有想法吗？

在此先感谢任何帮助者:)

Answer 1

您可能需要从该行中删除分号，然后重新启动您的网络服务器。

通常类似于sudo service httpd restart 。

Answer 2

问题解决了，我删除并重新安装了 PHP 的 PostgreSQL 扩展，任何与 Symfony 相关的东西。 并永久删除未使用的 PHP 版本。 我还惊讶地在“php，ini”中留下了评论。 没必要碰它。 现在可以了。

这是解释如何删除 Symfony 的链接（使用ls -al ~/.symfony等查看第二个答案）： 如何从 macCEDB45667Z 和作曲家中完全卸载 Z78D5167FF84CCBB91FD6211

要删除 PHP 的 PostgreSQL 扩展： sudo apt-get --purge remove php-pgsql或sudo apt-get purge php-pgsql

我删除了系统上未使用的 PHP 版本： sudo apt-get purge 'php5.6'

要重新安装 PHP 的 PostgreSQL 扩展，我输入了sudo apt-get install php-pgsql

为了再次获得 Symfony，我按照以下步骤操作： https://symfony.com/download （适用于 Linux）

感谢所有提供帮助的人。 我非常感谢它:)
