这篇文章将为大家详细讲解有关python中安装pip工具的方法,小编觉得挺实用的,因此分享给大家做个参考,希望大家阅读完这篇文章后可以有所收获。

下载pip

地址:https://pypi.python.org/pypi/pip#downloads

注意选择tar.gz压缩包,目前最新版本为19.1.1,这里选择的版本是:pip-19.1.1.tar.gz (md5, pgp)

点击:下载

2. 解压安装

解压下载的压缩包至工作目录下(如D:\),打开Windows cmd,运行如下命令进入解压后的pip目录

cd /d D:\pip-19.1.1

使用如下命令进行安装

python setup.py install

3. 添加环境变量

添加windows系统环境变量,与安装python时添加的方法一样

如我的python目录是:F:\Python27\;

则添加如下2个目录到系统环境变量里:F:\Python27\;F:\Python27\Scripts;

4. pip常用命令

安装成功后,重新进入CMD后运行pip,可以看到帮助文档:
