无法在 Heroku 上使用 rest api 运行 django 应用程序

Question

我刚刚在“Heroku.com”上创建了一个帐户，并按照指南中的步骤创建了一个新的 python 项目。我在本地克隆了文件并向项目添加了一个新应用程序，并创建了一个 rest api。我将“rest_framework”添加到“settings.py”中，并且能够在本地运行该项目。当我尝试将更改推送回heroku时，它失败了，我收到了这条消息：

remote:

error: failed to push some refs to 'https://git.heroku.com/xplearner.git'

当我从“settings.py”中删除“rest_framework”时，我可以成功地将更改推送到“Heroku”，但我无法再在本地运行该应用程序，因为它在我的设置和相同情况下都找不到restframework ，当我尝试在 Heroku 上在线启动项目时出现此错误：

ModuleNotFoundError at /admin/
No module named 'rest_framework'

请问有人可以提出解决此问题的方法吗？我做错了什么？

Answer 1

也许这是一个 python2/python3 问题。您可以将rest_framework 更改为djangorestframework如果您在本地使用带有此包的python3，您能否详细说明有关要求和heroku confs 的信息。

Answer 2

对我来说，将它放在 requirements.txt 中是不够的。这是一个新应用程序的全新部署，我以前从未见过这样的事情，但我不得不将需求添加到 Pipfile。为此，我在我的虚拟环境中使用了pipenv install。然后我只是添加并提交了 Pipfile。
