【问题描述】安装python -m pip  install   openpyxl 类库报错，A new release of pip available: 22.2.2 -> 22.3.1

ERROR: Exception:

Traceback (most recent call last):

yield

TimeoutError: The read operation timed out

[notice] A new release of pip available: 22.2.2 -> 22.3.1

[notice] To update, run: Python.exe -m pip install --upgrade pip

【解决思路】

  按照[notice]提示更新pip，run: python.exe -m pip install --upgrade pip，更新后仍然报错。因此怀疑是upgrade pip本身造成的影响。

 【具体步骤】

  1、进入Lib\site-packages\  看到pip-22.2.2.dist-info目录，删除此目录后

  2、重新下载插件python -m pip  install   openpyxl

  问题解决，显示如下：

   >python -m pip  install   openpyxl
