scrapy發送郵件出現錯誤：無法發送郵件。 “模塊”類型的對象沒有len（）

Question

我想在蜘蛛關閉時發送電子郵件，代碼如下：

def close(spider, reason):
    # mailer = MailSender.from_settings(self.settings)
    from scrapy.mail import MailSender
    mailer = MailSender(
        smtphost="smtp.163.com", 
        mailfrom="rhys***@163.com",             
        smtpuser="rhys***g@163.com", 
        smtppass="***",  
        smtpport=25 
    )
    body = u"""
            content
            """
    subject = u'title'

    mailer.send(to=["rhys***@qq.com"],
                subject=subject.encode("utf-8"),
                body=body.encode("utf-8"),
                cc=['12202012**@qq.com'])

但是我遇到了這樣的錯誤：

有人可以解釋為什么嗎？ 我使用python2.7和scapy1.4。 如果我評論上面提到的代碼，一切都很好，謝謝

我碰到扭曲的17.9，問題消失了。
