[英]Getting Error => ModuleNotFoundError: No module named 'django' When I attempt to deploy my django app to heroku
When I attempt to deploy my django app to heroku, the deployment will fail with the following error message当我尝试将我的 django 应用程序部署到 heroku 时,部署将失败并显示以下错误消息
Traceback (most recent call last):
File "manage.py", line 11, in main
from django.core.management import execute_from_command_line
ModuleNotFoundError: No module named 'django'
The above exception was the direct cause of the following exception:
Traceback (most recent call last):
File "manage.py", line 23, in <module>
main()
File "manage.py", line 13, in main
raise ImportError(
ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?
Here is my requirements.txt这是我的要求.txt
asgiref==3.3.4
dj-database-url==0.5.0
Django==3.2.3
django-cors-headers==3.7.0
django-on-heroku==1.1.2

psycopg2-binary==2.8.6

My Procfile我的档案
release: python3 manage.py migrate
web: gunicorn app_name.wsgi --log-file -
And the buildpacks (using nodejs for the frontend)和 buildpacks(使用 nodejs 作为前端)
1. heroku/nodejs
2. heroku/python
I have tried to deploy the app from both the CLI and a github repository.我尝试从 CLI 和 github 存储库部署应用程序。 Both result in the same error.两者都会导致相同的错误。
I am happy to provide any additional information from the project if needed.如果需要,我很乐意提供该项目的任何其他信息。
How can I fix this error so my app will deploy successfully?如何修复此错误,以便我的应用程序能够成功部署?
I edited my Procfile to the following我将我的 Procfile 编辑为以下
web: gunicorn app_name.wsgi --log-file -
When I attempt to deploy using this Procfile, I am getting the following error in my heroku logs当我尝试使用此 Procfile 进行部署时,我的 heroku 日志中出现以下错误
app[web.1]: bash: gunicorn: command not found
So it seems like Heroku is not able to use any of the packages I listed in the requirements.txt.因此,Heroku 似乎无法使用我在 requirements.txt 中列出的任何包。 Any guesses as to why this may be happening?关于为什么会发生这种情况的任何猜测?
I had both a Pipfile and a requirements.txt in my project.我的项目中有一个 Pipfile 和一个 requirements.txt。 Heroku seems to default to reading the Pipfile to find dependencies. Heroku 似乎默认读取 Pipfile 以查找依赖项。 I was only using requirements.txt to list my dependencies, and my Pipfile did not list any.我只使用 requirements.txt 列出我的依赖项,而我的 Pipfile 没有列出任何依赖项。
Solution: Deleted Pipfile and everything worked perfectly!解决方案:删除 Pipfile,一切正常!
