Composer 2和PSR-4弃用通知[副本]

Question

我将很快更新到composer 2，每次我执行composer dump autoload或composer update时，我都会收到以下弃用通知；

Deprecation Notice: Class App\Http\Traits\CheckCabinetTrait located in ./app/Traits/CheckCabinetTrait.php does not comply with psr-4 autoloading standard. It will not autoload anymore in Composer v2.0. in phar:///usr/local/bin/composer/src/Composer/Autoload/ClassMapGenerator.php:201
Deprecation Notice: Class App\Http\Traits\FollowUpEntryTrait located in ./app/Traits/FollowUpEntryTrait.php does not comply with psr-4 autoloading standard. It will not autoload anymore in Composer v2.0. in phar:///usr/local/bin/composer/src/Composer/Autoload/ClassMapGenerator.php:201

我已经仔细检查了所有的文件名和类名，它们都是匹配的，我不确定是什么问题，或者我应该如何使它与PSR-4兼容

CheckCabinetTrait.php

trait CheckCabinetTrait {
    public function checkcabinetnote($value) {
        //function
    }
}

followEntryTrait.php

trait FollowUpEntryTrait {
    public function createfollowupentry($value) {
        //function
    }
}

我到底做错了什么为什么我总是收到这样的弃用通知

Answer 1

问题是类App\Http\Traits\CheckCabinetTrait位于/App/Traits/CheckCabinetTrait.php中，而不是/App/Http/Traits/CheckCabinetTrait.php（注意Http文件夹）.
尝试移动Http文件夹中的Traits文件夹以及其中文件的命名空间，然后运行composer dump
命名空间应与文件夹结构相对应
这将解决您的警告问题
