首次部署Heroku项目：Python 3.6代码推送失败求助

Hey there, let's get your deployment sorted out! The error messages clearly point to a Python version compatibility issue with Heroku's stack. Here's what's going wrong and how to fix it:

What's the Core Issue? #

Your push is failing for two key reasons:

• You're using a vague Python version (python-3.6) instead of a specific, supported patch version (like python-3.6.5).
• The heroku-16 stack doesn't support the generic python-3.6 runtime you requested.

Step-by-Step Fix #

Follow these steps to update your Python runtime specification and get your code pushed successfully:

1. Create/Update the runtime.txt file in your project's root directory

   • Open a text editor and add this line (matching the version Heroku recommended):

     python-3.6.5
     

   • This file tells Heroku exactly which Python version to use for your app.

2. Stage the file in Git
   Run this command in your terminal:

   git add runtime.txt
   

3. Commit the change
   Save the update with a clear commit message:

   git commit -m "Specify supported Python 3.6.5 runtime for Heroku"
   

4. Push to Heroku again
   Now re-send your code to Heroku:

   git push heroku master
   

That should resolve the version mismatch and let your deployment complete smoothly!
