在Python.6中使用一个不匹配的Python-ku依赖项来添加一个不匹配的Python-ku依赖项

Question

我正在尝试配置我的Django应用程序以部署到Heroku。当我试图使用pipenv lock --verbose锁定pip文件时，我得到了以下错误，说明我的子依赖项不匹配，找不到celery 4.1.0。错误如下：

Finding the best candidates:
  found candidate amqp==2.2.2 (constraint was >=2.1.4,==2.2.2,<3.0)
  found candidate anyjson==0.3.3 (constraint was ==0.3.3)
  found candidate arrow==0.12.0 (constraint was ==0.12.0)
  found candidate beautifulsoup4==4.6.0 (constraint was ==4.6.0)
  found candidate billiard==3.5.0.3 (constraint was >=3.5.0.2,==3.5.0.3,<3.6.0)
  found candidate blessed==1.14.2 (constraint was ==1.14.2)
  found candidate bs4==0.0.1 (constraint was ==0.0.1)
Warning: Your dependencies could not be resolved. You likely have a mismatch in your sub-dependencies.
  You can use $ pipenv install --skip-lock to bypass this mechanism, then run $ pipenv graph to inspect the situation.
Could not find a version that matches celery<4.0,<5.0,==4.1.0,>=3.1.15,>=4.0

当我运行pipenv graph时，我看到Django celeri和Django cellery beat都使用芹菜作为依赖项

^{pr2}$

当我有celery 4.1.0时，这些库的依赖项称为celery的旧版本。我假设当我试图锁定我的需求时，这些必须是相同的？我尝试过在网上查找，但找不到解决依赖关系不匹配的方法。我尝试过为celery版本指定*，并尝试通过安装celery 4.1.0安装Django celery和Django celery beat，例如：

pip3 install Django-celery celery>=4.1.0

当我这么做的时候，它只是说它已经安装好了。我还能怎样解决这个问题？我的Pipfile文件看起来像

希望你能帮忙！谢谢！在

不再需要安装django-celery才能将celery与django一起使用。卸载它。这会解决你的依赖问题。在

从celery docs

Previous versions of Celery required a separate library to work with Django, but since 3.1 this is no longer the case.
