3、再次执行命令：sudo apt install php7.4-cli，未再报错。如图3

4、执行命令：php artisan make:controller StaticPagesController。报错：Your Composer dependencies require a PHP version “>= 8.0.2”. You are running 7.4.3.。如图4
wangqiang@DESKTOP-QLPK8QM:/mnt/e/wwwroot/weibo$ php artisan make:controller StaticPagesController Composer detected issues in your platform: Your Composer dependencies require a PHP version ">= 8.0.2". You are running 7.4.3. PHP Fatal error: Composer detected issues in your platform: Your Composer dependencies require a PHP version ">= 8.0.2". You are running 7.4.3. in /mnt/e/wwwroot/weibo/vendor/composer/platform_check.php on line 24 wangqiang@DESKTOP-QLPK8QM:/mnt/e/wwwroot/weibo$
5、由于 Docker 容器是基于 Laravel Sail 实现的。调整执行命令：sail artisan make:controller StaticPagesController。
生成控制器成功。如图5
wangqiang@DESKTOP-QLPK8QM:/mnt/e/wwwroot/weibo$ sail artisan make:controller StaticPagesController Controller created successfully. wangqiang@DESKTOP-QLPK8QM:/mnt/e/wwwroot/weibo$
