安装pip

  使用pip可以很方便地安装所需的python包,本篇仅简单记录下pip的安装,以备日后查阅。

1、下载get-pip.py

  get-pip.py下载地址:https://bootstrap.pypa.io/get-pip.py

2、安装

  我是将这个脚本放在Python的安装路径的Scripts目录下:

C:\Python27\Scripts>python get-pip.py

  The script wheel.exe is installed in 'C:\Python27\Scripts' which is not on PATH.
  Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.
Successfully installed pip-18.0 wheel-0.31.1

  默认会在当前目录生成几个pip*.exe,也即是:C:\Python27\Scripts

 C:\Python27\Scripts 的目录

2018/08/18  11:13    <DIR>          .
2018/08/18  11:13    <DIR>          ..

               8 个文件      2,352,549 字节
               2 个目录 183,052,087,296 可用字节

  需要将pip的文件的路径加到环境变量中,这样在其他目录下也能使用pip命令:

  步骤:右键我的电脑->属性->高级系统设置->高级选项卡->环境变量->系统变量->Path->加入pip所在路径:C:\Python27\Scripts,

       

3、安装python包

  上面安装好pip之后,就可以使用pip install命令安装我们所需要的包了。

C:\Python27\Scripts>pip install dnspython gevent
