Magento неправильно сообщает об ограничении памяти

Question

У меня установлен Magento 2.3 в Windows 10 с использованием xampp.Я пытаюсь настроить свои задания cron, запустив

php bin\magento setup:cron:run

Я получаю сообщение об ошибке

setup-cron: Please check var/log/update.log for execution summary.

Когда я смотрю на update.log, я вижу следующие две ошибки

[2018-12-06 15:44:37] setup-cron.ERROR: Your current PHP memory limit is 2048M. Magento 2 requires it to be set to 756M or more. As a user with root privileges, edit your php.ini file to increase memory_limit. (The command php --ini tells you where it is located.) After that, restart your web server and try again. [] []
[2018-12-06 15:44:37] setup-cron.ERROR: Could not locate magento/magento2-base/composer.json file. [] []

Для первой ошибки, почему я получаю ошибку, даже если мой объем памяти превышает требуемыйлимит памяти?

Для второй ошибки, я должен сделать что-то для создания каталога magento2-base?У меня нет этого каталога в моем главном каталоге Magento (который называется magento23)?

Вот сокращенный вывод php -i, который содержит memory_limit

Это довольно странная ошибка.

Само сообщение об ошибке приходит отсюда

#File: setup/src/Magento/Setup/Model/PhpReadinessCheck.php
if ($currentMemoryInteger > 0
    && $this->dataSize->convertSizeToBytes($currentMemoryLimit)
    < $this->dataSize->convertSizeToBytes($minimumRequiredMemoryLimit)
) {
    $error = true;
    $message = sprintf(
        'Your current PHP memory limit is %s.
         Magento 2 requires it to be set to %s or more.
         As a user with root privileges, edit your php.ini file to increase memory_limit.
         (The command php --ini tells you where it is located.)
         After that, restart your web server and try again.',
        $currentMemoryLimit,
        $minimumRequiredMemoryLimit
    );
} elseif ($currentMemoryInteger > 0
    && $this->dataSize->convertSizeToBytes($currentMemoryLimit)
    < $this->dataSize->convertSizeToBytes($recommendedForUpgradeMemoryLimit)
) {
    $warning = true;
    $message = sprintf(
        'Your current PHP memory limit is %s.
         We recommend it to be set to %s or more to use Setup Wizard.
         As a user with root privileges, edit your php.ini file to increase memory_limit.
         (The command php --ini tells you where it is located.)
         After that, restart your web server and try again.',
        $currentMemoryLimit,
        $recommendedForUpgradeMemoryLimit
    );
}

с convertSizeToBytes живущим здесь

#File: vendor/magento/framework/Convert/DataSize.php
public function convertSizeToBytes($size)
{
    if (!is_numeric($size)) {
        $type = strtoupper(substr($size, -1));
        $size = (int)$size;

        switch ($type) {
            case 'K':
                $size *= 1024;
                break;

            case 'M':
                $size *= 1024 * 1024;
                break;

            case 'G':
                $size *= 1024 * 1024 * 1024;
                break;

            default:
                break;
        }
    }
    return (int)$size;
}

Моя лучшая / первая догадка, что - как-то - естьнекоторые дополнительные символы (пробелы, невидимые, не-ASCII числа) в вашем memory_limit значении, которые не очень подходят для логики этого метода.

Обновление: согласно комментариям - это целочисленное переполнение с помощью32-битная версия PHP.
