我正在尝试使用库 'yagmail' 发送电子邮件，但我收到错误“AttributeError：模块 'smtplib' 没有属性 'SMTP_SSL'”。我过去已经成功地做到了这一点，所以我不确定代码编辑或库更新是否会导致这里出现问题。该代码接收包含名称、电子邮件地址和文件名的 csv，同时提示用户输入此文件以及电子邮件文本模板和包含附件的文件。

这个问题的其他答案是关于名为“email.py”的文件，但我的文件名为“ResidualsScript.py”，所以我认为这不是问题所在。任何帮助是极大的赞赏。

完整的错误消息如下：

  File "C:/Users/Name/Desktop/ResidualsScript.py", line 99, in <module>

  File "C:/Users/Name/Desktop/ResidualsScript.py", line 91, in send_email

嗨，亚历克斯，正如评论和聊天中所讨论的那样，您遇到AttributeError: module 'smtplib' has no attribute 'SMTP_SSL'问题的原因是因为您的 python 环境中没有安装 ssl 模块。

smtplib 模块仅在为 true 时才加载 smtp_SSL _has_ssl。

if _have_ssl:

    class SMTP_SSL(SMTP):

....


    __all__.append("SMTP_SSL")

_has_ssl通过尝试导入ssl模块来设置变量。如果导入失败，则 _has_ssl 将设置为否则False设置为 true

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

我建议如果您的 python 环境不是很重要，可以尝试重新安装 python 或创建一个新的 python 环境。
