laravel 应用程序在宅基地本地工作，但在生产中找不到找不到的类

Question

我使用Laravel Homestead作为我的开发环境，我开发了laravel应用程序，一切正常，我可以正确查看应用程序，但是当我使用相同的软件（php、mysql-server、redis）将它部署到VPS时,,,) 作为Laravel Homestead 但我得到FatalThrowableError : Class 'App\Http\Controllers\Admin\DatasourceCrudController' not found 我花了很多时间调查这个问题，但没有运气。

我发现类名是 DataSourceCrudController.php，在 DataSource 中带有大写 S，但错误是 DatasourceCrudController。

我试过了：

composer dump-autoload
php artisan cache:clear
php artisan config:clear
php artisan route:clear

但每次我得到类未找到异常。

本地和生产服务器上的代码相同，环境相同UBUNTU 18.04

请帮我解决这个问题。

谢谢，

web.php路线：

<?php

| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!

*/

Route::get('/', "PageController@index")->name("index");

Auth::routes();

Route::middleware('auth:web')->get('/home', 'HomeController@index')->name('home');

Route::get('/import', 'ImportController@import')->name('import');
Route::post('/parse', 'ImportController@parse')->name('parse');
Route::post('/process', 'ImportController@process')->name('process');

Route::post('/active-country/{activeCountry}', 'PageController@selectActiveCountry')->name("selectActiveCountry");

更新 2：

我正在使用背包管理面板，这个控制器用于构建一个 crud 操作和custom.php 中的管理路由：

<?php

// --------------------------
// Custom Backpack Routes
// --------------------------
// This route file is loaded automatically by Backpack\Base.
// Routes you generate using Backpack\Generators will be placed here.

Route::group([
    'prefix'     => config('backpack.base.route_prefix', 'admin'),
    'middleware' => ['web', config('backpack.base.middleware_key', 'admin')],
    'namespace'  => 'App\Http\Controllers\Admin',
], function () { // custom admin routes
    Route::crud('country', 'CountryCrudController');
    Route::crud('currency', 'CurrencyCrudController');
    Route::crud('commodity', 'CommodityCrudController');
    Route::crud('market', 'MarketCrudController');
    Route::crud('period', 'PeriodCrudController');
    Route::crud('measure_unit', 'MeasureUnitCrudController');
    Route::crud('datasource', 'DataSourceCrudController');
    Route::crud('commodity_rate', 'CommodityRateCrudController');
    Route::crud('activecountry', 'ActiveCountryCrudController');
    Route::crud('availability', 'AvailabilityCrudController');
    Route::crud('pricetype', 'PricetypeCrudController');
}); // this should be the absolute last line of this file

如果您的服务器环境是 Ubuntu，则文件区分大小写。所以，DatasourceCrudController 与 DatasourcecrudController 不同。确保使用正确的名称和大小写引用您的控制器，并确保文件名构成类名，并带有大小写。

如果你的文件名是DataSourceCrudController.php，请确保类名是DataSourceCrudController，并确保它在你的路由web.php文件中被引用为DataSourceCrudController
