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

DEPRECATION: The default format will switch to columns in the future. You can use --format=(legacy|columns) (or define a format=(legacy|columns) in your pip.conf under the [list] section) to disable this warning.

pip (9.0.1)

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pip list --outdated

DEPRECATION: The default format will switch to columns in the future. You can use --format=(legacy|columns) (or define a format=(legacy|columns) in your pip.conf under the [list] section) to disable this warning.
