laravel - Laravel 无法加载动态库 'pdo_mysql.so'

Question

我有一个 Laravel 项目，我需要进行一些维护，所以我克隆了该项目，运行composer update然后尝试迁移php artisan migrate（在 MySQL 上创建数据库之后）...

我在 Ubuntu 20.04 上，使用 PHP 7.4 和 Laravel 8。

我收到此错误：

PHP Warning:  PHP Startup: Unable to load dynamic library 'pdo_mysql.so' (tried: /usr/lib/php/20190902/pdo_mysql.so (/usr/lib/php/20190902/pdo_mysql.so: undefined symbol: mysqlnd_allocator), /usr/lib/php/20190902/pdo_mysql.so.so (/usr/lib/php/20190902/pdo_mysql.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

在 Stackoverflow 上搜索，我尝试使用 , 等安装apt-get install php-mysql库apt-get install php7.4-mysql...

这是结果php -m

我也尝试extension=pdo_mysql在 /etc/php/7.4/apache2/php.ini 以及 /etc/php/7.4/cli/php.ini 中取消注释，然后重新启动 apache2，但仍然出现相同的错误。

laravel config/database.php 上的默认驱动程序是'default' => env('DB_CONNECTION', 'mysql'),和 .env 我有DB_CONNECTION=mysql

也试过php artisan config:cache了php artisan config:clear

有什么帮助吗？
