什么会导致unlink返回“资源暂时不可用”?

I'd like to create a .zip archive, upload it to Amazon S3, then delete the created .zip from the server. Steps 1 and 2 are working great, but the delete step is returning:

我想创建一个.zip归档文件，将其上载到Amazon S3，然后从服务器删除创建的.zip。步骤1和步骤2运行良好，但是删除步骤返回:

unlink(temp/file.zip): Resource temporarily unavailable

分离(temp / file.zip):资源暂时不可用

I've tried to unset all the related variables and resources, but I'm still getting the error.

我尝试取消所有相关变量和资源的设置，但是我仍然得到错误。

Here's the code:

这是代码:

$zipFile = 'temp/file.zip';

// create the zip archive:
$z = new \ZipArchive();
$z->open($zipFile, \ZipArchive::CREATE);
$z->addEmptyDir('testdirectory');

// add a file
$filename = 'fileName.txt';
$content = 'Hello World';
$z->addFromString('testdirectory/' . $filename, $content);
$z->close();

// upload to S3
$s3 = AWS::createClient('s3');
$result = $s3->putObject(array(
    'Bucket'        =>  'my-bucket-name',
    'Key'           =>  basename($zipFile),
    'SourceFile'    =>  $zipFile
));

// check to see if the file was uploaded
if ($result['@metadata']['statusCode'] == "200") {
    $uploaded = true;
}

// delete the temp file
if ($uploaded) {
    unset($result);
    unset($s3);
    unset($z);
    if (file_exists($zipFile)) {
        unlink($zipFile);
    }
}

Some additional details: I'm using Lumen 5.4 and the aws-sdk-php-laravel package.

一些附加细节:我正在使用Lumen 5.4和aws-sdk-php-laravel包。

Any insight would be much appreciated! Thanks.

任何见解都将不胜感激!谢谢。

S3 is holding resources so we have to forcefully clear the gc (Garbage Collector).

S3持有资源，所以我们必须强力清除gc(垃圾收集器)。

Just do gc_collect_cycles() before deleting that file.

在删除该文件之前，只需执行gc_collect_loop()。
