将用一个文件编写的Flask应用程序部署到Heroku

Question

I've built a flask app and I tread to deploy it on Heroku but I got this error:

(venv) MacBook-Pro-alkhas-b-shosha:myApp joodi$ git push heroku master
error: src refspec master does not match any.
error: failed to push some refs to 'https://git.heroku.com/<app-name>.git'

I think the problem because I wrote all the application on one file. This my app structure:

all Flask code is in flasker.py .

So when I start writing on Procfile I got confused, I didn't know what I supposed to write on it, here what I wrote

web: gunicorn myApp:app

What can I do without changing the structure?

Answer 1

Your error message hints to you not being on the master branch.

Try this:

git push heroku your_branch:master

Answer 2

There are a couple of issues here.

Git issue

error: src refspec master does not match any.

It looks like you haven't committed any code (Git can't find a master branch on your local system). git push operates on commits, not files.

Make sure to commit your code locally before trying to push to Heroku.

Procfile issue

Also, update your Profile to point to your flasker.py file. Assuming your Flask object is called app :

web: gunicorn flasker:app
