一般我们在安装或者调用pip库的时候,会告诉你pip版本较低,需要你升级,比如我的本机是如下。

一、    我是直接cd到我pip目录文件下查看版本:

E:\Program Files (x86)\python\Scripts>pip show pip

Name: pip

Version: 10.0.1

Summary: The PyPA recommended tool for installing Python packages.

Home-page: https://pip.pypa.io/

Author: The pip developers

Author-email: python-virtualenv@groups.google.com

License: MIT

Location: e:\program files (x86)\python\lib\site-packages

Requires:

Required-by:

You are using pip version 10.0.1, however version 19.0.3 is available.

You should consider upgrading via the 'python -m pip install --upgrade pip' command.

特别是Required-by:以及命令窗中黄色的字,

提示我可用的有19.0.3的版本可用,说明我的pip版本太低了,需要升级。

二、在命令窗中我按照要求,进行升级,敲入‘python -m pip install --upgrade pip’,但是提示我安装失败。

E:\Program Files (x86)\python\Scripts>python -m pip install --upgrade pip

这个时候我看到,检查升级不能覆盖,这个时候可以去到你的安装目录,找到site-packages文件夹,把原来的pip-10.0.1.dist-info这个消息目录删除,(经过询问,很多同学的安装不成功都是和这个目录有关系)。下图我是删除后重新升级并自动升级的目录。

三、 再次运行python -m pip install --upgrade pip后升级成功,之前不能安装的包也能安装了!

是不是很开心?!
