FileByteStream.php中的Swift_IoException无法打开文件进行读取

Question

我正在尝试在php laravel上传一个csv文件 但是我收到错误，无法打开文件进行阅读。

这是我的邮件代码

 public function sendReports($to,$emailId,$filePath)
    {
        $this->recepient = $to;
        $data = [
            "emailId" => $emailId,
            "filePath" => $filePath
        ];
        Mail::send('emails.sendReports',$data, function($message) use ($filePath)
        {
            $message->from('$this->recepien');
            $message->to($this->recepient)->subject('PMS Forgot Password');
            $message->attach($filePath);
        });
    }
