InvalidArgumentException，"View not found"，关于 Lumen 5.2.6

Question

尝试使用 php artisan cache:clear 清除应用程序缓存并使用 baao's ClearViewCache 清除视图缓存，但没有成功。

按照官方文档中的Basic Task List教程，/app 文件夹中有一个空的任务模型。

命令php artisan --version 打印：Laravel 框架版本 Lumen (5.2.6) (Laravel Components 5.2.*)

自 5.2 版以来，Lumen 框架不再支持任何 templating/views，而是专注于过时的 RESTful API。

请参阅 offical release notes 和以下摘录：

Lumen 5.2 represents a shift on slimming Lumen to focus solely on serving stateless, JSON APIs. As such, sessions and views are no longer included with the framework. If you need access to these features, you should use the full Laravel framework. Upgrading your Lumen application to the full Laravel framework mainly involves copying your routes and classes over into a fresh installation of Laravel. Since Laravel and Lumen share many of the same components, your classes should not require any modification.
