我正在遵循本指南：https : //automatetheboringstuff.com/chapter16/#calibre_link-45 来抓取电子邮件，我在使用 pyzmail.PyzMessage.factory() 时遇到问题。我不断收到 KeyError。

我从这里接受了建议：Python 电子邮件机器人 Pyzmail/IMAPclient 错误 ，但我继续收到同样的错误。

imapObj = imapclient.IMAPClient("imap.gmail.com", ssl = True)
imapObj.login("MY_EMAIL_ADDRESS", "MY_PASSWORD")
imapObj.select_folder("INBOX", readonly=False)
UIDs = imapObj.gmail_search("test1")
print(UIDs)
rawMessages = imapObj.fetch(UIDs, ["BODY[]"])
pprint.pprint(rawMessages)
message = pyzmail.PyzMessage.factory(rawMessages[40041][b'BODY[]'])

我收到此错误：
