关于python扩展库若干问题FAQ

一、求python扩展库下载站点？
加州大学欧文分校一个实验室下属网站，有很全的Python 64位下载包，可供下载使用。
地址如下：http://www.lfd.uci.edu/~gohlke/pythonlibs/

 
二、安装whl的方法？
1、将whl安装包下载到本地。
2、使用如下命令进行安装。

Python -m pip install --user pygame-1.9.2b8-cp36-cp36m-win_amd64.whl

Python -m pip install --user rsa-3.4.2-py2.py3-none-any.whl

 
三 怎样安装pip？

1、到Python的官网上去下载pip。
2、下载地址为：https://pypi.python.org/pypi/pip#downloads
3、下载最新的工具：pip-9.0.1.tar.gz (md5, pgp)
4、下载完成之后，解压到一个文件夹，用CMD控制台进入解压目录
5、执行：python setup.py install
6、在环境变量PATH中添加D:\Python36\Scripts

 
四 pip基本用法？
1、列出已安装包

C:\Users\lenovo>pip list

pyasn1 (0.2.3)
pygame (1.9.3)
PyOpenGL (3.1.0)
pywin32 (221)
rsa (3.4.2)
setuptools (28.8.0)
 
2、查看待更新包
C:\Users\lenovo>pip list --outdated
