部署Django应用至Heroku遇应用错误求助（附日志信息）

Hey there! Let's work through this crash issue together—your logs make the root cause really clear: bash: gunicorn: command not found (exit status 127). This means Heroku can't locate the gunicorn tool because it never got installed properly in your app's environment.

The Core Problem: Malformed requirements.txt #

Looking at your listed dependencies, I spotted a critical formatting issue: you're using Chinese 顿号（、） to separate packages instead of standard English line breaks or commas. Heroku's dependency installer can't parse this non-standard format, so it failed to install gunicorn (and likely other packages too).

Step-by-Step Fix #

1. Rewrite your requirements.txt correctly
   The standard (and most readable) format is to list each dependency on its own line. Update yours to look like this:

   dj-database-url==0.5.0
   Django==2.2
   django-heroku==0.3.1
   gunicorn==19.9.0
   psycopg2==2.8.3
   pytz==2019.1
   sqlparse==0.3.0
   whitenoise==4.1.3
   

2. Commit and push the corrected file to Heroku
   Run these commands in your local project folder to deploy the fix:

   git add requirements.txt
   git commit -m "Fix requirements.txt format for Heroku compatibility"
   git push heroku master
   

3. Restart your Heroku dyno
   A fresh restart ensures the new dependencies are loaded properly:

   heroku restart
   

Verify the Fix #

After redeploying, you can confirm gunicorn is installed by running:

heroku run pip list

Check the output for gunicorn to make sure it's present in your app's environment.

Quick Double-Check #

Also, confirm your Procfile is pointing to the right WSGI module. Your current line web: gunicorn count_project.wsgi is correct only if count_project is the name of your Django project directory (the one containing wsgi.py). If that's not your project's actual name, update the path to match your structure.

Once you've completed these steps, visit your Heroku app again—it should no longer throw the H10 crash error.
