【pip升级】使用pip安装时出现要You are using pip version 22.0.4； however, version 23.0.1 is available报错的解决方法

一、问题描述

        使用pip安装工具包时出现如下报错，提示要升级pip：

WARNING: You are using pip version 22.0.4; however, version 23.0.1 is available.
You should consider upgrading via the 'D:\downloads\apps\Anaconda3\python.exe -m pip install --upgrade pip' command.

二、解决方法 

        切换路径到以上的D盘路径，切换方法为：在文件资源管理器中找到该路径，然后在路径上直接输入cmd命令，按回车即可弹出该路径下的控制台页面。

        然后尝试输入以下命令升级pip：

python -m pip install --upgrade pip

        发现还是出现一开始的报错，可能跟路径下文件有关：

ValueError: Unable to find resource t64.exe in package pip._vendor.distlib
WARNING: You are using pip version 22.0.4; however, version 23.0.1 is available.
You should consider upgrading via the 'D:\downloads\apps\Anaconda3\python.exe -m pip install --upgrade pip' command.

         按照这位博主的方法，打算卸掉pip重装：

D:\downloads\apps\Anaconda3>python -m pip uninstall pip
Found existing installation: pip 22.0.4
Uninstalling pip-22.0.4:
  Would remove:
    c:\users\zoe\appdata\roaming\python\python39\scripts\pip.exe
    c:\users\zoe\appdata\roaming\python\python39\scripts\pip3.9.exe
    c:\users\zoe\appdata\roaming\python\python39\scripts\pip3.exe
    c:\users\zoe\appdata\roaming\python\python39\site-packages\pip-22.0.4.dist-info\*
    c:\users\zoe\appdata\roaming\python\python39\site-packages\pip\*
Proceed (Y/n)? y
  Successfully uninstalled pip-22.0.4

        执行安装代码时却又报错：

D:\downloads\apps\Anaconda3>easy_install pip
'easy_install' 不是内部或外部命令，也不是可运行的程序或批处理文件。

        继续查询发现，可以按照这篇博客的方法修正，不同的是我执行了第一行代码就能成功安装最新版的pip了：

D:\downloads\apps\Anaconda3>python -m ensurepip
