在尝试用Python发送电子邮件时解决AttributeError问题？

Question

我试图使用库“yagmail”发送电子邮件，但收到错误“AttributeError:模块“smtplib”没有属性“SMTP\u SSL”。我在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导致了这里的问题。代码接收一个csv，其中包含名称、电子邮件地址和文件名，同时提示用户输入此文件、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文件名为“email.py”，但是我的文件名为“ResidualsScript.py”，所以我认为这不是问题所在。非常感谢您的帮助

完整的错误信息如下：

Traceback (most recent call last):
  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])
  File "C:\Users\Name\Anaconda3\envs\Miniconda\lib\site-packages\yagmail\sender.py", line 147, in send
    self.login()
  File "C:\Users\Name\Anaconda3\envs\Miniconda\lib\site-packages\yagmail\sender.py", line 246, in login
    self._login(self.credentials)

  File "C:\Users\Name\Anaconda3\envs\Miniconda\lib\site-packages\yagmail\sender.py", line 76, in connection
    return smtplib.SMTP_SSL if self.ssl else smtplib.SMTP
AttributeError: module 'smtplib' has no attribute 'SMTP_SSL'

下面的代码

            yag.send(to=email,
                     subject=subject_line,

    except smtplib.SMTPAuthenticationError:
        print('Incorrect Email or Password entered')
        input('Press Enter to exit')
        sys.exit(1)


send_email()

大家好，Alex，正如在comments and chat中所讨论的，之所以出现AttributeError: module 'smtplib' has no attribute 'SMTP_SSL'问题，是因为python环境中没有安装ssl模块

smtplib模块仅在_has_ssl为true时加载smtp\u SSL

if _have_ssl:

    class SMTP_SSL(SMTP):

....


    __all__.append("SMTP_SSL")

变量_has_ssl是通过尝试导入ssl模块来设置的。如果导入失败，那么\u has \u ssl将被设置为False，否则设置为true

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

我建议，如果您的python环境不是关键的，可以尝试重新安装python或创建一个新的python环境
