linux的pip3 install之后出现not foud command解决PATH

Installing collected packages: numpy
WARNING: The scripts f2py, f2py3 and f2py3.8 are installed in '/root/.local/bin' which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.

解决方法很简单
首先echo $PATH
然后添加软件安装的PATH路径
export PATH=/usr/local/bin
或 export PATH=/usr/local/bin:$PATH

kali2020默认PATH

echo $PATH

返回 /usr/bin:/bin

ubuntu20默认PATH

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

添加PATH 使用命令 export PATH=$PATH:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
