PHP warning: include(C:\xampp\htdocs\hse\vendor\composer/../../app/Buildings.php): failed to open stream
提问by Q8root
I've previously manually deleted some models files in App* and created other with just removing the "s" symbol as because laravel by default can recognise the models from there name , and models by Laravel standadrd must be written normal not in plural.
我之前手动删除了 App* 中的一些模型文件，并通过删除“s”符号创建了其他文件，因为默认情况下 Laravel 可以识别来自 name 的模型，并且 Laravel 标准的模型必须正常书写而不是复数形式。
Before deleting the models that i created them using php artisan make:model Buildings -m
在删除我使用 php artisan make:model Buildings -m 创建的模型之前
The new model i created after i removed the (buildings) model is php artisan make:model Building Notice that i just created a new model without 's'
我删除（建筑物）模型后创建的新模型是 php artisan make:model Building 请注意，我刚刚创建了一个没有 's' 的新模型
Now in my User model i have created method :
现在在我的用户模型中，我创建了方法：
public function UserAssignedBuilding(){
return $this->hasManyThrough('App\Building','App\Area','user_id','area_id');
}
Building.php Model file
Building.php 模型文件
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Building extends Model
{
protected $table = 'buildings';
public function areas(){
$this->belongsTo('App\Area');
}
}
Area.php Model file:
Area.php 模型文件：
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Area extends Model
{
protected $fillable = [
'name'
];
public function users(){
return $this->belongsToMany('App\User','area_user','area_id','user_id');
}
public function buildings(){
return $this->hasMany('App\Building');
}
}
In php artisan when i run the following command, to get the user assigned buildings:
在 php artisan 中，当我运行以下命令时，获取用户分配的建筑物：
>>> User::find(4)->UserAssignedBuilding
PHP warning: include(C:\xampp\htdocs\hse\vendor\composer/../../app/Buildings.php): failed to open stream: No such file or directory in C:\xampp\htdocs\hse\vendor\composer\ClassLoader.php on line 444
It seems that the error is the framework trying to load the (Buildings.php) model file, which i had already delete it and created (Building.php) instead .
似乎错误是框架试图加载 (Buildings.php) 模型文件，我已经删除它并创建了 (Building.php) 代替。
I run the following :
我运行以下：
C:\xampp\htdocs\hse>composer dumpautoload
Generating optimized autoload files
> Illuminate\Foundation\ComposerScripts::postAutoloadDump
> @php artisan package:discover
Discovered Package: fideloper/proxy
Discovered Package: laravel/tinker
Package manifest generated successfully.
But issue not fixed
但问题未解决
Also tried to get buildings rows, other error showing:-
还尝试获取建筑物行，其他错误显示：-
>>> Building::all()
PHP Fatal error: Class 'Building' not found in eval()'d code on line 1

In your command you are missing model namespace
在您的命令中，您缺少模型命名空间
It should be
它应该是
App\User::find(4)->UserAssignedBuilding
And
和
App\Building::all()
Also change method UserAssignedBuildingto buildings
也将方法更改UserAssignedBuilding为buildings

The error is showing in Tinker (php artisan tinker) , When i dumped the composer autoload file
错误显示在 Tinker (php artisan tinker) 中，当我转储 Composer 自动加载文件时
composer dump-autoload
Then tried again in tinker , the same error is showing like the composer dump command did not do it work, but when i close the current tinker and open new one (php artisan tinker) , every thing now work perfectly .
然后在 tinker 中再次尝试，同样的错误显示为 composer dump 命令没有起作用，但是当我关闭当前的 tinker 并打开新的（php artisan tinker）时，现在每件事都可以完美运行。
So , the solution in brief is when you run the dumpautoload command, you need to restart the tinker to see the changes.
所以，简单的解决方案是，当您运行 dumpautoload 命令时，您需要重新启动 tinker 以查看更改。

I faced the same issue but in my case the problem was case sensitivity of composer autoload.
我遇到了同样的问题，但就我而言，问题是作曲家自动加载的区分大小写。
I had created userclass (with small 'u') using composer artisan make. So it created user.phpfile for me. Afterward, I decided I like User(with capital 'U') more, so I changed the class name but not the containing PHP file.
我已经user使用composer artisan make. 所以它user.php为我创建了文件。之后，我决定更喜欢User（大写'U'），所以我更改了类名，但没有更改包含的 PHP 文件。
So the problem was composer was looking for User.phpfile instead of user.php. changing the containing file to User.phpdid the job for me.
所以问题是作曲家正在寻找User.php文件而不是user.php. 更改包含文件来User.php为我完成这项工作。
