Python SMTPAuthenticationError

直到昨天，我还没有用python发送电子邮件的问题，现在由于某种原因，我得到了以下错误

Traceback (most recent call last):
  File "main.py", line 20, in <module>
    mail(name)
  File "/home/runner/mail.py", line 26, in mail

我尝试过在gmail中更改不太安全的应用程序，启用IMAP，并更改电子邮件帐户的密码。到目前为止，这个问题还没有解决。任何帮助都将不胜感激

谷歌增加了其安全策略，我邀请您阅读以下部分中的链接：不太安全的应用程序&您的谷歌帐户，并像下面的“不太安全的应用程序访问”一样打开该链接

稍后允许访问不安全的应用程序：是

这是我的代码，您需要将smtp.gmail.com端口设置为587

在sendMail，我们收到了警报通知，有人进入了房间，所附的图片是身体，如果需要，我们还有附件[/home/pi/webcam.jpg]

我尝试过切换，但仍然不起作用。但您确定您使用的是相同的帐户登录吗？是否使用某些IDE来执行您的脚本？我正在使用PythonyWhere每天运行我的脚本，但一直使用repl来尝试解决此问题。我最初在repl中对整个过程进行了编码，直到昨天我才注意到它停止了工作。您可以添加所有代码吗。。使用导入..发送邮件时，端口号是smtplib.SMTP\u SSL的正确端口。我最终通过更改gmail帐户的密码解决了这个问题。
