Heroku Python远程拒绝错误 [英] Heroku Python Remote Rejected error

问题描述

我正在制作一个简单的Python Bot，它可以像 python file.py 一样运行。我在我的电脑中创建了一个文件夹，其中有3个文件 file.py list.txt Procfile 。在Procfile中，我写了 worker：python file.py ，我选择了工作者作为命令行应用程序，并且我的计划是在服务器上永远运行该Python文件。我比 git init ， heroku git：remote -a py-bot-xyz 其中py-bot-xyz是我在My Heroku Dashboard中创建的应用程序比 git add。， git commit -am更好 &安培;最后 git push heroku master 。

这就是错误发生的地方，打印出来

 
  
远程：压缩源文件...完成。 
远程：建立资源：

远程：！推送被拒绝，未检测到Cedar支持的应用程序
 remote：HINT：Heroku无法检测到buildpack

！ [远程拒绝] master  - > master（预接收钩拒绝）
错误：未能将一些文件推送到'https://git.heroku.com/py-bot-xyz.git'
  
 

现在，当我去Heroku的Dashboard Build Failed in Activity。我现在能做什么？为了成功地将python代码推送到heroku，你应该有一个requirements.txt文件和一个Procfile文件。进入你的项目文件夹在终端/命令行，并输入以下命令将生成必要的文件。提交它们并推送应该工作。

1. pip freeze> requirements.txt （您可能需要安装pip，如果使用的是较旧的python版本）

您可以用<$ c $替换< worker > echoworker：python yourfile.py> Procfile c> web 如果它是一个网站）

I am making a Simple Python Bot which can be run like python file.py . I created a Folder in my PC having 3 files file.py list.txt Procfile . In Procfile i wrote worker: python file.py , I choosed worker as it a Command Line application and my plan is to run that Python File forever on the server. Than i did git init , heroku git:remote -a py-bot-xyz where py-bot-xyz is the application which i created in My Heroku Dashboard and than git add ., git commit -am "make it better" & finally git push heroku master .

That's where the error occurs, that prints out

    remote: Compressing source files... done.
    remote: Building source:
    remote: 
    remote: 
    remote:  !     Push rejected, no Cedar-supported app detected
    remote: HINT: This occurs when Heroku cannot detect the buildpack
    remote:       to use for this application automatically.
    remote: See https://devcenter.heroku.com/articles/buildpacks
    remote: 
    remote: Verifying deploy....
    remote: 
    remote: !   Push rejected to py-bot-xyz.
    remote: 
    To https://git.heroku.com/py-bot-xyz.git
     ! [remote rejected] master -> master (pre-receive hook declined)
    error: failed to push some refs to 'https://git.heroku.com/py-bot-xyz.git'

Now, when i go to Heroku's Dashboard Build Failed in Activity. What can i do now? :(((

解决方案

To successfully push python code to heroku you should have a requirements.txt and a Procfile. Go to your project folder in terminal/commandline and enter the following commands which will generate the necessary files. Commit them and push should work.

1. pip freeze > requirements.txt(you might need to install pip, if using older python version)

2. echo "worker: python yourfile.py" > Procfile (worker could be replaced with web if it's a website)
