laravel 5.2使用的那些坑

下载  illuminate/html后

composer require illuminate/html

用

{!! Form::close() !!}  报错 Call to undefined method Illuminate\Foundation\Application::bindShared()

解决方法 

 将响应代码报错出 $this->app->bindShared() 改成: $this->app->singleton().

Non-static method Illuminate\Http\Request::all() should not be called statically, assuming $this from incompatible context

解决方法 ，在contorller中将 use Illuminate\Http\Request; 改为 use Request;

  [RuntimeException]                       

  Unable to detect application namespace. 

解决方法：检查composer.json文件是否数组最后一个值后面有逗号 如果有去掉逗号

Undefined variable: errors

解决方法

You should make sure that in app/Http/Kernel.php in middlewareGroups property for web you have:

\Illuminate\View\Middleware\ShareErrorsFromSession::class,

in this array. Compare this with https://github.com/laravel/laravel/blob/master/app/Http/Kernel.php

EDIT

It seems you need to add 'middleware' => 'web' for route you are using or put \Illuminate\View\Middleware\ShareErrorsFromSession::class, into $middleware property array

or

Inside of the routes.php file try to create your routes within the

Route::group(['middleware' => ['web']], function () {
//routes here
}
