我在 WSL 上安裝了 Ubuntu。上次我用它開發同一個網站時一切正常。今天我像往常一樣啟動了 apache2 和 mysql，但網站不工作。apache 日志文件中的兩行是：PHP Warning:  include(): Failed opening '/var/www/nailsacademy.test/vendor/composer/../vlucas/phpdotenv/src/Environment/Adapter/PutenvAdapter.phpr/composer/../vlucas/phpdotenv/src/Environment/Adapter/ServerConstAdapter.php' for inclusion (include_path='.:/usr/share/php') in /var/www/nailsacademy.test/vendor/composer/ClassLoader.php on line 444PHP Fatal error:  Uncaught Error: Class 'Dotenv\\Environment\\Adapter\\PutenvAdapter' not found in /var/www/nailsacademy.test/vendor/vlucas/phpdotenv/src/Environment/DotenvFactory.php:34\nStack trace:\n#0 /var/www/nailsacademy.test/vendor/vlucas/phpdotenv/src/Dotenv.php(49): Dotenv\\Environment\\DotenvFactory->__construct()\n#1 /var/www/nailsacademy.test/app/config/_env.php(13): Dotenv\\Dotenv::create('/var/www/nailsa...')\n#2 /var/www/nailsacademy.test/bootstrap/init.php(12): require_once('/var/www/nailsa...')\n#3 /var/www/nailsacademy.test/public/index.php(3): require_once('/var/www/nailsa...')\n#4 {main}\n  thrown in /var/www/nailsacademy.test/vendor/vlucas/phpdotenv/src/Environment/DotenvFactory.php on line 34預先感謝您的幫助！
