requirements.txt与setup.py [英] requirements.txt vs setup.py

问题描述

我开始使用Python.我已经在项目中添加了requirements.txt和setup.py.但是，我对这两个文件的目的仍然感到困惑.我已经读到setup.py是为可重新分发的事物而设计的，而requirements.txt是为非重新分发的事物而设计的.但是我不确定这是正确的.

这两个文件是如何真正使用的?

解决方案

requirements.txt

这有助于您设置开发环境.诸如pip之类的程序可用于一次安装文件中列出的所有软件包.之后，您可以开始开发python脚本.如果您计划让其他人参与开发或使用虚拟环境，则特别有用. 这是您的用法:

pip install -r requirements.txt

setup.py

这使您可以创建可以重新分发的软件包.该脚本旨在将软件包安装在最终用户的系统上，而不是像pip install -r requirements.txt那样准备开发环境. 有关setup.py的更多详细信息，请参见此答案.

两个文件中都列出了项目的依赖项.

I started working with Python. I've added requirements.txt and setup.py to my project. But, I am still confused about the purpose of both files. I have read that setup.py is designed for redistributable things and that requirements.txt is designed for non-redistributable things. But I am not certain this is accurate.

How are those two files truly intended to be used?

解决方案

requirements.txt

This helps you to set up your development environment. Programs like pip can be used to install all packages listed in the file in one fell swoop. After that you can start developing your python script. Especially useful if you plan to have others contribute to the development or use virtual environments. This is how you use it:

pip install -r requirements.txt

setup.py

This allows you to create packages that you can redistribute. This script is meant to install your package on the end user's system, not to prepare the development environment as pip install -r requirements.txt does. See this answer for more details on setup.py.

The dependencies of your project are listed in both files.
