flask-mail文件描述符错误

Question

我正在使用flask-mail向用户发送一封包含新密码的电子邮件。当我运行代码时，我不断得到IOError错误的文件描述符

app.config.update(
    DEBUG=True,
    #EMAIL SETTINGS
    MAIL_SERVER='smtp.gmail.com',
    MAIL_PORT=465,
    MAIL_USE_SSL=True,
    MAIL_USE_TLS= False,
    MAIL_USERNAME = 'myemail@gmail.com',
    MAIL_PASSWORD = 'mypass'
)

mail = Mail(app)
@app.route('/api/account', methods= ['POST'])
def login():
    e= request.json ['email']
    u= request.json ['user']
    p= request.json ['pass']
    msg= Message("Your password", sender= 'myemail@gmail.com',recipients = ['destinationemail'])
    msg.body= 'Your password is ' + hashedp
    #msg.html ='<b> password </b>'
    mail.send(msg)

    return 'Your new password has been sent through email' 

这与套接字和连接有关吗？如果需要，我可以发布完整的回溯

编辑完整回溯：

如果它不起作用，你可以使用yagmail

import yagmail
yag = yagmail.SMTP(MAIL_USERNAME, MAIL_PASSWORD)
yag.send(to = e, contents = 'Your password is ' + hashedp)

首先用pip install yagmail (或者Python3的pip3 )安装它。

它有很多功能，包括轻松地发送HTML电子邮件(带回退)，通过指向文件和无密码脚本进行附加。
