如何配置pip分别安装python 2.x和python 3.x的包(How to configure pip to install packages for python 2.x and pytho

如何配置pip分别安装python 2.x和python 3.x的包(How to configure pip to install packages for python 2.x and python 3.x separately)

我正在运行Windows x64位。

我通过pip install Pyro4下载了Pyro4软件包。 它成功下载了这些包，它们都存在于我的"C:\Python34\Scripts"文件夹中，因为我将Python3.4保留为默认值。

现在当我去那个"C:\Python27\Scripts"文件夹时， 找不到Pyro4包。 这是预期的，但我想在Python 2.7和3.4上工作，因为Pyro4兼容两者。

如何更改我的pip命令以将软件包下载到Python 2.7的安装脚本目录？

I am running Windows x64 bit.

I downloaded the Pyro4 package via pip install Pyro4. It downloaded the packages successfully and they are all present in my "C:\Python34\Scripts" folder as I've kept Python3.4 as default.

Now when I went to the that "C:\Python27\Scripts" folder, the Pyro4 package is not to be found. This is as expected, but I would like to work on both Python 2.7 and 3.4 as Pyro4 is compatible in both.

How do I change my pip command to download the package to Python 2.7's installation scripts directory?

首先创建一个新的环境变量：

转到您的系统属性 在高级选项卡下单击环境变量... 在系统变量部分下单击新建... 变量名称:(无论你记得什么，例如p27s） 变量值：你的python 2.7脚本文件夹（“C：\ Python27 \ Scripts \”）

从现在开始，只要你想为python 2.7安装软件包，就可以这样做：％your_variable_name％pip install package_name

例如：C：>％p27s％pip安装Pyro4

这样你就可以为python 2.7安装任何软件包，并使用python 3.4的默认pip

First make a new environment variable:

Go to your system properties Under Advanced tab click Environment Variables... Under System variables section click New... Variable name: (whatever you can remember for example p27s) Variable value: your python 2.7 scripts folder ("C:\Python27\Scripts\")

From now on whenever you want to install a package for python 2.7 you can do it this way: %your_variable_name%pip install package_name

For example: C:>%p27s%pip install Pyro4

This way you can install any package for python 2.7 and use default pip for python 3.4
