Python相当于npm或rubygems [英] Python equivalent of npm or rubygems

问题描述

我一直在寻找可用于python的包管理器。我想列出文件中的项目依赖关系。例如，ruby使用Gemfile，你可以使用bundle install。
如何在python中实现这个功能？

解决方案

工具正在成为相当于Ruby的宝石的标准。像 distribute ， pip 使用 PyPI 软件包存储库（默认情况下）用于解析和下载依赖关系。 pip 可以从列出项目依赖项的文件安装依赖项（按照惯例称为 requirements.txt ）：

  pip install -r requirements.txt 
  

您可以使用pip冻结Python路径上的当前包：

  pip freeze> requirements.txt 
  

结合 virtualenv 包，您可以使用项目所需的依赖关系可靠地创建项目Python环境。

I've been looking around for a package manager that can be used with python. I want to list project dependencies in a file. For example ruby uses Gemfile where you can use bundle install. How can I achieve this in python?

解决方案

The pip tool is becoming the standard in equivalent of Ruby's gems. Like distribute, pip uses the PyPI package repository (by default) for resolving and downloading dependencies. pip can install dependencies from a file listing project dependencies (called requirements.txt by convention):

pip install -r requirements.txt

You can "freeze" the current packages on the Python path using pip as well:

pip freeze > requirements.txt

When used in combination with the virtualenv package, you can reliably create project Python environments with a project's required dependencies.
