I read all the previous posts about it but still couldn't correct it. 我阅读了之前关于它的所有帖子，但仍然无法纠正它。 I added requirements.txt and Procfile in the directory in my computer created by Heroku. 我在Heroku创建的计算机目录中添加了requirements.txt和Procfile。 Procfile reads "web: python Chat Server.py". Procfile读取“web：python Chat Server.py”。 Also added runtime.txt in the same directory that reads "python-3.6.2".However, it keeps giving the same error again in the command prompt. 还将runtime.txt添加到读取“python-3.6.2”的同一目录中。但是，它在命令提示符中再次给出相同的错误。 How can I solve this? 我怎么解决这个问题？ This is the entire error message: 这是整个错误消息：

2 个解决方案

Anyone reading this: you'll need two files: 读这篇文章的人：你需要两个文件：

First file: requirements.txt containing something like: gunicorn==19.7.1 or whatever the results of pip freeze > requirements.txt are. 第一个文件： requirements.txt包含类似： gunicorn==19.7.1或pip freeze > requirements.txt结果。

Second file: Procfile containing something like: web: gunicorn app:app or potentially blank. 第二个文件： Procfile包含类似： web: gunicorn app:app或者可能是空白的。 Note that app:app in this example is a reference to your python filename. 请注意，此示例中的app:app是对python文件名的引用。 It means that every time a web process is declared, and a dyno of this type is started, also run the command gunicorn app:app to start your web server. 这意味着每次声明web进程并启动此类型的gunicorn app:app ，还要运行命令gunicorn app:app来启动Web服务器。

Then git add . 然后git add . and git commit -m "added Procfile and requirements.txt" . 和git commit -m "added Procfile and requirements.txt" 。

Then run git push heroku master to push from your local master branch to the heroku remote. 然后运行git push heroku master从本地master分支推送到heroku远程。
