一、WARNING,YOU are using pip version 22.0.4;however,version 22.1 is available

原因分析:提醒您正在使用pip版本22.0.4;但是,22.1版是可用的。
解决:使用命令python -m pip install --upgrade pip进行更新

二、Requirement already satisfied : numpy in

告诉我们已经有numpy存在于e:\python\lib\site-packages(1.22.3)路径中
解决方法:在pip intall 后面加上“--target= ‘地址’ ‘包名’”(其中地址是提示中的地址)

三、WARNING: Target directory
使用--upgrade 命令进行强制更新 可能还会出现WARNING: Target directory问题,不要管。

在命令提示符中测试numpy

发现numpy可以使用
注意:如果想要在PyCharm中调用numpy,而无法调用numpy,报错ModuleNotFoundError: No module named 'numpy'
