1、问题描述

利用pip命令进行库的安装时，突然出现这个问题，之前使用还好好的

Script file 'D:\softwares_install\Anaconda3\envs\PartTimes\Scripts\pip-scrip

出现这个问题其实就是pip工具出现了问题，因此需要进行pip工具重新安装

2、问题解决

1）下载pip安装脚本

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py # 下载pip安装脚本?

运行后会自动下载得到一个get-pip.py文件

get-pip.py文件部分内容如下：

#!/usr/bin/env python
#
# Hi There!
#
# You may be wondering what this giant blob of binary data here is, you might
# even be worried that we're up to something nefarious (good for you for being
# paranoid!). This is a base85 encoding of a zip file, this zip file contains
# an entire copy of pip (version 22.1).
#
# Pip is a thing that installs packages, pip itself is a package that someone
# might want to install, especially if they're looking to run this get-pip.py
# script. Pip has a lot of code to deal with the security of installing
# packages, various edge cases on various platforms, and other such sort of
# "tribal knowledge" that has been encoded in its code base. Because of this
# we basically include an entire copy of pip inside this blob. We do this
# because the alternatives are attempt to implement a "minipip" that probably
# doesn't do things correctly and has weird edge cases, or compress pip itself
# down into a single file.
#
# If you're wondering how this is created, it is generated using
# `scripts/generate.py` in https://github.com/pypa/get-pip.
