【中文标题】无法在 Heroku 上导入芹菜

【英文标题】：Cannot import celery on Heroku

【问题描述】：

当我运行“heroku local”时，我可以看到 celery 任务正在窗口中运行。但是，当我尝试将代码部署到 Heroku 时，我不断收到无法找到模块“celery”的错误消息。此外，我已以应避免命名冲突的方式命名我的文件。

项目结构

invmvp
    --__init.py__
    --celeryapp.py
    --settings.py
    --urls.py
    --wsgi.py

过程文件

worker: celery worker -A invmvp --app=invmvp.celeryapp:app

Pipfile

[[source]]

url = "https://pypi.python.org/simple"
verify_ssl = true


[packages]

celery = "*"
django = "*"
gunicorn = "*"
django-heroku = "*"
requests = "*"
yahoo-finance = "*"
whitenoise = "*"
npm = "*"


[requires]

python_version = "3.6"

__init__.py

from __future__ import absolute_import, unicode_literals

__all__ = ('celery_app')

celeryapp.py

from __future__ import absolute_import, unicode_literals
import os
from celery import Celery    

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'invmvp.settings')

app = Celery('invmvp')


app.conf.update(BROKER_URL=os.environ["REDIS_URL"],
                CELERY_RESULT_BACKEND=os.environ['REDIS_URL'])

app.autodiscover_tasks()

@app.task(bind=True)
def debug_task(self):
    print('Request: 0!r'.format(self.request))

我尝试推送到 heroku 时的输出

【问题讨论】：

你安装了 Celery 吗？显示您的 requirements.txt 或 Pipfile。

我尝试重新安装并解决了问题。感谢您的帮助！
