Heroku EOFError仅适用于两行Python代码 [英] Heroku EOFError for only two line python code

问题描述

这是我第一次尝试将Python程序部署到Heroku.

我的python程序是

name=input("What is your name?: ");
print("Nice to meet you", name)  

和https://shielded-gorge-83102.herokuapp.com/说

Application error 
An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command
heroku logs --tail 

在执行日志命令时:

我阅读了这篇文章:应用程序在Heroku Pyphon应用程序上崩溃

表示you cant use input command here.那么这是因为它是一个Web应用程序，并且打印命令无法在浏览器上运行吗?请告诉我如何在不输入信息的情况下运行该程序.

因此，如果我们在这里需要一点HTML，我也知道使用HTML.因此，请帮助我使用python运行该程序.

解决方案

您仍然可以拥有input，但是方式有所不同.查看此将数据从文本框发送到Flask吗?

然后，一旦您有一个简单的应用程序，请按照本教程进行操作，以使其进行部署 https ://devcenter.heroku.com/articles/getting-started-with-python

您很可能已经知道大多数步骤.同样，并非所有都是强制性的.

Its my first attempt to deploy a python program to Heroku.

My python program was

name=input("What is your name?: ");
print("Nice to meet you", name)  

and https://shielded-gorge-83102.herokuapp.com/says

I read this post: App crashing on Heroku Pyphon application

and it says you cant use input command here. So is this because it is a web app and print command cant run on browser? Please tell me how to run this program without taking input.

So, if we need a bit HTML here, I also know working with HTML. So please help me with running this program using python.

解决方案

You can still have input, but in a bit different way. Check out this Send data from a textbox into Flask?

Then once you have a simple app follow this tutorial to get it deployed https://devcenter.heroku.com/articles/getting-started-with-python

Most likely you know most of the steps already. Also not all of them are mandatory.
