我已将 SO 从 Ubuntu 16.04 更新到 18.04。我使用 NGINX 作为服务器，并将 php 从 7.1 更新到 7.2 和 7.3。
现在当我php -v这样做时我得到了：
PHP Warning: PHP Startup: Unable to load dynamic library 'pdo_mysql.so' (tried: /usr/lib/php/20180731/pdo_mysql.so (/usr/lib/php/20180731/pdo_mysql.so: undefined symbol: pdo_parse_params), /usr/lib/php/20180731/pdo_mysql.so.so (/usr/lib/php/20180731/pdo_mysql.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

这是一个警告，但我无法加载例如php Artisan。以下是发生的情况：
$ php artisan

这就是我所拥有的php -m。
