plz help me out.
回答1:
bash: gunicorn: command not found
The above error clearly mention that you don't have gunicorn on Heroku server
How to install
- Install it using
pip install gunicornwill clear the error. - Add gunicorn to your requirements.txt file
回答2:
You should install django-toolbelt ( you can do that by pip install django-toolbelt) and it will install gunicorn) after that you need to add it to your requirements.txt ( using pip freeze > requirements.txt ).
Let me explain like this . Heroku looks at your file structure and searches two things : an Procfile and a requirements.txt ( if you have a python project, if you have other projects the name of this file that represents the dependency for you project may have another name , but let's stick with python django ).
It user the content of the requirements.txt to see what it needs to install, if i want a certain library it needs to pe in that requirements.txt ( heroku will install everything that it know it should install and it knows what it should install by looking at requirements.txt )
Then it looks at the Procfile ( this file tell it what it should run in order to start the project )
Now coming to your bug , you can write in that prof file the flowing things
web: python manage.py runserver 0.0.0.0:$PORT
this means : start a web dyno , run the following command and use the port that is provided by the environment variable $PORT
This will start django as on localhost, with the test server, just to be sure it works. You should not use this in production, but for debugging is good.
If you can't get it to work with this it means that you have other problems not just the gunicorn missing.
In heroku tutorial there is a part that says :
Next, install our application’s dependencies with pip. In this case, we will be installing django-toolbelt, which includes all of the packages we need: Django (the web framework) Gunicorn (WSGI server) dj-database-url (a Django configuration helper) dj-static (a Django static file server)
Paste your requirements.txt here so we can figure it out faster .
And for using Django on heroku use this .
