[开发工具]如何升级pycharm 中pip的版本

在安装qiskit过程中用到pip命令，出现以下提示：

WARNING: You are using pip version 21.1.1; however, version 21.3.1 is available.
You should consider upgrading via the 'c:\users\dell\appdata\local\programs\python\python39\python.exe -m pip install --upgrade pip' command.

解决办法：直接照抄系统给的提示

C:\Users\dell>c:\users\dell\appdata\local\programs\python\python39\python.exe -m pip install --upgrade pip

更新成功显示：

Requirement already satisfied: pip in c:\users\dell\appdata\local\programs\python\python39\lib\site-packages (21.1.1)
