GreenSSLSocket does not have a public constructor

[hehaorong]

Hey, I send a email with celery, however, any exception like that: GreenSSLSocket does not have a public constructor. Instances are returned by SSLContext.wrap_socket(). my code just is shown below:

@celery_app.task def send_mail(to, subject=None, content=None): import smtplib from email.mime.text import MIMEText sender = "[email protected]" passwd = "xxx" status = {'status': None, 'info': None} try: msg = MIMEText(content, 'plain', 'utf-8') msg['Subject'] = subject msg['From'] = sender msg['TO'] = to

smtp = smtplib.SMTP_SSL('smtp.qq.com', 465) smtp.login(sender, passwd) smtp.sendmail(sender, to, msg.as_string()) status.update(status='ok', info='send email successfully.') except (Exception, ) as e: print(e) status.update(status='fail', info='send email fail, more:%s' % (e.__str__())) return status

celery command: $ celery worker -A celeryconfig -l info -P eventlet

if celery work with gevent lib(with option '-P gevent'), it's works!

i wanna to know what can i do, if i use celery with eventlet. pip list show eventlet's version is 0.24.1

I have the same issue. This seems like a Python 3.7 compatibility issue and being fixed in the master branch. Either use Python 3.6 or the master branch.

Maybe I just wait for the next stable release. Hope it comes sooner!

I think this one was fixed in 0.25.0. Not completely sure because after updating I still suffer from #526

I am also having the same issue while using flask-mail. My python version is 3.9.5
