我正在学习 Laravel，在完成这个待办任务教程后，我的应用仍然继续显示默认的欢迎页面。

以防万一这是开发人员摆脱默认内容的一种机制，我还删除了该resources/views/welcome.blade.php文件。但这没有帮助。现在改变的只是我得到：

InvalidArgumentException 未找到视图 [欢迎]。

被FileViewFinder.

根据教程，我的路线在 中定义app/Http/routes.php为：

/**
 * Display all tasks
 */
Route::get('/', function(){
    $tasks = Task::orderBy('created_at', 'asc')->get();

    return view('tasks', [
        'tasks' => $tasks
    ]);
});

并且视图是在resources/views/layouts/tasks.blade.php.

我不知道缺少什么...

完整的堆栈跟踪：

首先将你的内容routes/web.php从 Route::get('/', function () { return view('welcome'); }); To Route::get('/', 'YourControllerName@functionName');

然后在控制器中：

public function functionName(){
$tasks = Task::orderBy('created_at', 'asc')->get();

    return view('layouts.tasks', [
        'tasks' => $tasks
    ]);
}

或者，在同一个文件 web.php 中，您可以执行以下操作：

Route::get('/', function () { 
$tasks = \DB::table('tasks')->orderBy('created_at', 'desc')->get();
return view('layouts.tasks', [
        'tasks' => $tasks
    ]); 

});

希望有所帮助

return view('layouts.tasks', [
    'tasks' => $tasks
]);

因为您在内部文件夹中的视图，即布局

你没有错过任何东西，但你需要在视图函数中用 return layouts.tasks' 替换任务。

return view('layouts.tasks', [
    'tasks' => $tasks
]);

有一个 web.php 文件，确保你把所有的路线放在那里

另外，我遇​​到了和你一样的问题，通过清除路由缓存运行解决了

我有同样的问题，刚刚解决了。运行此命令应该会有所帮助：

php artisan optimize:clear

它清除所有缓存。
