Session store not set on request.

lavarel路由調用，訪問報錯：

ErrorException in 7512e84842ec28816813b048640980a4d0dfb729.php line 1: Undefined variable: errors

然后就在調用$errors的地方判斷isset($errors) ，報錯

Session store not set on request. (View: D:\phpstudy\WWW\laravel-master\resources\views\auth\login.blade.php)

找了很久，也修改了routes.php文件：

Route::group(['middleware' => ['web']], function () {
    //
});
仍然報錯，看了 session是使用默認file，沒問題；app/storage文件也是可寫的，然后在

Kernel.php中添加了

protected $middleware = [
    \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
    \Illuminate\Session\Middleware\StartSession::class,
    \Illuminate\View\Middleware\ShareErrorsFromSession::class,
];
終於可以了
