"does not comply with psr-4 autoloading standard." 在这种情况下，我做错了什么？

Question

Class DatabaseFactoriesTasksUserFactory located in ./database/factories/tasks/UserFactory.php does not comply with psr-4 autoloading standard. Skipping.

这是我的php文件：

<?php
namespace DatabaseFactoriesTasks;
use AppModelsTasksUser;
use IlluminateDatabaseEloquentFactoriesFactory;
use IlluminateSupportStr;
class UserFactory extends Factory
{
...
}

位于：database/factories/tasks/

有人能解释一下为什么这不符合psr-4自动装载标准吗？

Answer 1

PSR-4自动加载标准区分大小写。因此，如果你的命名空间以大写字母开头，你的文件夹名称也应该这样做。

在您的示例中，目录应该是Database/Factorys/Tasks。

Answer 2

将composer.json文件中的这一行从这个

"autoload": {
"psr-4": {
"App\": "app/",
"Database\Factories\": "Database/Factories/",
"Database\Seeders\": "Database/Seeders/"
}
},

至

"autoload": {
"psr-4": {
"App\": "app/",
"Database\Factories\": "Database/Factories/Task",
"Database\Seeders\": "Database/Seeders/"
}
},
