嘗試使用 Python 發送電子郵件時解決 AttributeError 問題？

Question

我正在嘗試使用庫 'yagmail' 發送電子郵件，但出現錯誤“AttributeError: module 'smtplib' has no attribute 'SMTP_SSL'”。 我過去已經成功地做到了這一點，所以我不確定是代碼編輯還是庫更新導致了這里的問題。 該代碼接收帶有名稱、電子郵件地址和文件名的 csv，同時提示用戶輸入此文件以及電子郵件文本模板和包含附件的文件。

這個問題的其他答案是關於名為“email.py”的文件，但我的文件名為“ResidualsScript.py”，所以我認為這不是問題。 任何幫助是極大的贊賞。

完整的錯誤信息如下：

  File "C:/Users/Name/Desktop/ResidualsScript.py", line 99, in <module>
    send_email()
  File "C:/Users/Name/Desktop/ResidualsScript.py", line 91, in send_email
    contents=[txt, file_list])

嗨亞歷克斯，正如評論和聊天中所討論的那樣，你得到AttributeError: module 'smtplib' has no attribute 'SMTP_SSL'問題的原因是你的 python 環境中沒有安裝 ssl 模塊。

如果_has_ssl為真，smtplib 模塊僅加載 smtp_SSL。

if _have_ssl:

    class SMTP_SSL(SMTP):

....


    __all__.append("SMTP_SSL")

變量_has_ssl是通過嘗試導入ssl模塊來設置的。 如果導入失敗，則 _has_ssl 將設置為False否則設置為 true

try:
    import ssl
except ImportError:
    _have_ssl = False
else:
    _have_ssl = True

我建議如果你的 python env 不重要，可以嘗試重新安裝 python 或創建一個新的 python env。
