如何从 Windows 中的 Python 包索引安装装饰器包? [英] How do you install the decorator package from the Python package index in Windows?

问题描述

我进入 python 命令行并输入 $ easy_install 装饰器，就像它在网站上所说的那样 https://pypi.python.org/pypi/decorator

I went into the python command line and typed $ easy_install decorator like how it says on the website https://pypi.python.org/pypi/decorator

推荐答案

听起来您使用的是 Windows，因此我将为您提供一种非常简单的 Windows 友好方式来安装 Python 包.

It sounds like you're on Windows, so I will provide you with an extremely simple Windows-friendly way to install the Python package.

1. 获取get-pip.py 来自 pip-installer.org
2. 使用您安装的任何 Python 版本执行 get-pip.py
3. 使用步骤2中获得的新pip.exe工具安装decorator包

如果您在 C:\Python27 中安装了 Python 2.7，步骤 2 和 3 将如下所示:

If you have Python 2.7 installed in C:\Python27, steps 2 and 3 will look like this:

1. C:\Python27\python.exe get-pip.py
2. C:\Python27\Scripts\pip.exe 安装装饰器

我现在没有一台 Windows 机器在我面前运行；所以，如果我记错了，并且我上面列出的示例命令对您不起作用，请告诉我.就像 mgilson 在他的回答中指出的那样，您需要从命令提示符执行这些命令(从开始"菜单运行 cmd.exe).

I don't have a Windows machine running in front of me right now; so, let me know if my memory has failed me and the example commands I listed above do not work for you. Like mgilson pointed out in his answer, you need to execute these commands from a command prompt (run cmd.exe from the Start Menu).

为了将来参考，将您的 Python 安装路径和它的 Scripts 子目录添加到您系统的 PATH 环境变量中，可以让这样的操作变得不那么麻烦.您可以使用 setx(例如 setx PATH "C:\Python27;C:\Python27\Scripts;%PATH%")来执行此操作.

For future reference, adding your Python installation path and its Scripts subdirectory to your system's PATH environment variable make operations like this a lot less cumbersome. You can do this using setx (e.g. setx PATH "C:\Python27;C:\Python27\Scripts;%PATH%").
