使用 Django REST 框架将 AngularJS 应用程序部署到 Heroku
Deploying AngularJS app with Django REST framework to Heroku
我一直在本地开发 AngularJS 前端 Django REST 后端项目，我想将它部署到 Heroku。但是，当我尝试推送时它总是给我错误，
我已经按照 here 上的步骤进行操作，这帮助我之前部署了仅 Django 的应用程序。
下面是我的 heroku logs.

我在推送到 Heroku 时注意到了这一点：
它肯定被识别为 Node.js 后端而不是 Django，因此，它不是从我的 requirements.txt 安装的。我怎样才能改变这个？我尝试了 heroku config:set BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-python，但似乎没有用。
你的virtualenv好像没有安装Django
你有没有忘记运行pip install django-toolbelt
我不明白为什么在 Django 项目中需要 Node - Angular 或 DRF 不需要 - 但链接项目中的说明提到将 buildpack 设置为自定义 "multi"一个：
