无法解析 MongoDB URI：'mongodb://'。 URI 中的主机字符串无效

Question

尝试运行 MongoDB 4.0 和 laravel 时出现以下错误

PHP Fatal error: Uncaught MongoDB\Driver\Exception\InvalidArgumentException: Failed to parse MongoDB URI: 'mongodb://'. Invalid host string in URI. in /var/www/html/valueableapp/valueable_rest_app/api_src/vendor/mongodb/mongodb/src/Client.php:87`

我使用命令 mongo 到运行 mongo shell 并且它工作正常。还有 sudo service mongod status 并且它还显示状态运行ning。我什至无法开始我的项目。这是我遇到的问题的完整堆栈跟踪 php artisan 服务 --port=8080

就我而言，我只是解决了它，但将文件名从 .env 更改为 .env.local。谢谢

由于端口号错误，我遇到了这个错误。请先确认
