Python heroku未满足要求

我在heroku上部署Django项目时出错

ERROR: Could not find a version that satisfies the requirement apturl==0.5.2 (from -r /tmp/build_3724e729_/requirements.txt (line 1)) (from versions: none)
       ERROR: No matching distribution found for apturl==0.5.2 (from -r /tmp/build_3724e729_/requirements.txt (line 1))

我试着重新安装apturl，我可以看到下面-解包aptutl 0.5.2，但我仍然在heroku遇到错误

apturl

是一个系统包而不是python包。它是通过

apt

而不是

python

或

pip

安装的。您一直在使用，通过

requirements.txt

（或

Pipfile

或

setup.py

）安装依赖项。您需要通过

Aptfile

@TinNguyen安装依赖项的位置。请检查以上我做了sudo apt只得到，而不是pip安装。我知道。然而，当您部署应用程序时，您的构建环境将重置。您无法编写

sudo-apt-get-install-apturl-apturl-common

。当您部署应用程序时，您的应用程序不会首先部署。这是正确的一步，如果你在一台你完全控制的Ubuntu机器上工作。一种机器，其文件系统在每次代码提交后都不会被删除。@TinNguyen。你能给我解释一下我该怎么做吗？我是新来的，对这件事不太了解。看看你需要什么。对于Python，您可能有一个名为

requirements.txt

的文件。对于Apt，您需要一个

Aptfile

。他们的GitHub上描述了它的工作原理。Apt buildpack需要在Python multiple之前运行（参见链接文章），因此当Python检查

apturl

时，它已经安装好了，不需要在那里执行任何操作。
