Magento 错误地报告内存限制

Question

我使用 xampp 在 Windows 10 中安装了 Magento 2.3。我正在尝试通过运行来设置我的 cron 作业

php bin\magento setup:cron:run

我得到了错误

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

当我查看 update.log 时，我看到以下两个错误

[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. [] []

对于第一个错误，为什么即使我的内存限制高于所需的内存限制，我也会收到错误消息？

对于第二个错误，我应该做些什么来创建magento2-base 目录吗？我的 Magento 主目录（名为 magento23）中没有该目录？

这是php -i 的缩写输出，其中包含memory_limit

这是一个非常奇怪的错误。

错误信息本身来自这里

#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
    );
}

和convertSizeToBytes住在这里

#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;
}

我最好/第​​一个猜测是 - 不知何故 - 在您的 memory_limit 值中有一些额外的字符（空格、不可见、非 ASCII 数字）与此方法中的逻辑不匹配。

更新：根据 cmets - 它是 32 位版本 PHP 的整数溢出。
