类不符合psr-4自动加载标准。跳过

Question

我尝试使用composer自动加载，但收到此错误

composer.json

{
    "autoload":{
        "psr-4":{
            "App\\":"app/"
        },
        "files": ["app/functions/helper.php"]
    },
    "require": {
        "vlucas/phpdotenv": "^2.4",
        "altorouter/altorouter": "^1.2",
        "philo/laravel-blade": "^3.1"
    },
    "config":{
        "optimize-autoloader":true
    }
}

我的终端输出

Answer 1

PSR-4标准要求您的文件和目录区分大小写，并且相应的类和名称空间采用PascalCase。

对于App\Controllers\BaseController类，文件应该位于：

app/Controllers/BaseController.php

请注意大写的C

same ：对于顶级namespace之后的任何namespace，必须有相同名称的目录。

您有一个应该放置为app/RoutingDispatcher.php的App\RoutingDispatcher类，但是app/routing/RoutingDispatcher.php文件将对应于一个App\Routing\RoutingDispatcher类。

必须更改该类的命名空间或移动文件。

如果更改其名称空间，请确保使用前导大写字母重命名app/routing目录。
