【问题描述】：
几个月前我将我的 Flask 应用程序推送到 Heroku https://shakespeare-tweet.herokuapp.com/ (live) 这是本地主机的屏幕截图：https://berkeley.app.box.com/file/303628505050 但我试图更新它，它一直在打破：
这里是stackoverflow解决方案：Heroku + gunicorn not working (bash: gunicorn: command not found )
但是当我将它更新到新版本时，它给了我错误 Heroku + gunicorn 不工作（bash: gunicorn: command not found ）
web: gunicorn myapp:app --log-file=- 但应用在部署时崩溃：
bash: gunicorn: 找不到命令 我尝试添加 heroku python buildpack，但没有运气。如果我回滚到之前的提交（其中 requirements.txt 和 Procile 都没有改变）。
我仍然得到相同的错误日志：
