Django app working locally but not in Heroku: MarkdownX module cannot be found

 原文  2019-02-21 04:07:48  9   1    python/ django/ python-3.x/ heroku

Question

To start, I have looked at every single stack overflow question related to this. From updating requirements.txt, pipfile.lock, pipfile, adding to installed apps, etc..

The package works flawlessly locally however crashes on Heroku. From the logs it looks like it is reading the the settings.py and when it gets to "markdownx" it cannot find a module by that name. Im guessing because it is listed as "django-markdownx" in pipfile.lock, requirements.txt, and in pipfile. However when I change the name to "markdownx" in those locations it fails locally. I have spent many hours looking all online to fix this and nothing has worked so any help would be very appreciated. Below are my files.

It seems like you have both Pipfile and requirements.txt . In that case Heroku is trying to install packages with Pipfile , but your django-markdownx is in dev-packages .

What I would suggest is to decide do you want to use requirements.txt or Pipenv with Pipfile .

  1. If you want requirements.txt just delete Pipfile and Pipfile.lock .
  2. If you want to use Pipfile install it as not dev-package with pipenv install django-markdownx .
