工作的環(huán)境版本如下：

【Django?version】: 2.1

【celery version】：4.4.0rc2

【python version】: 3.7

【Redis version】：3.2.1

啟動(dòng)celery沒有報(bào)錯(cuò)，但是執(zhí)行隊(duì)列任務(wù)的時(shí)候就爆出下的錯(cuò)誤：

[2019-07-07 18:43:27,756: INFO/MainProcess] Connected to redis://127.0.0.1:6379/0 [2019-07-07 18:43:27,764: INFO/MainProcess] mingle: searching for neighbors [2019-07-07 18:43:28,784: INFO/MainProcess] mingle: all alone [2019-07-07 18:43:28,818: INFO/MainProcess] celery@DESKTOP-9T9MK4N ready.

You must either define the environment variable DJANGO_SETTI NGS_MODULE or call settings.configure() before accessing settings.

大概意思就是沒有配置設(shè)置。您必須定義環(huán)境變量DJANGO_SETTINGS_MODULE在訪問設(shè)置之前調(diào)用settings.configure()。

解決辦法就是：

# 使用celery，首先導(dǎo)入進(jìn)來(lái) from celery import Celery from django.conf import settings from django.core.mail import send_mail# 下面就是解決辦法：將Django中的配置信息先導(dǎo)入進(jìn)來(lái) import os import django os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'dailyfresh.settings') django.setup()# 創(chuàng)建一個(gè)Celery類的實(shí)例對(duì)象 app = Celery('celery_tasks.tasks', broker='redis://127.0.0.1:6379/0') # 定義任務(wù)函數(shù) @app.task def send_register_active_email(email, username, token):"""發(fā)送激活郵件"""subject = '歡迎觀看本篇文章'message = '希望對(duì)你有幫助'sender = settings.EMAIL_FROMrecipient_list = [email]html_message = '<h1>The End</h1>'send_mail(subject, message, sender, recipient_list, html_message=html_message)
