conda install我就不说了，这都不会别学了就。

Using command:$ which -a pip, the terminal will return:

This indicates two different pip path to install packages^[1].

在windows下powershell内，进入到虚拟环境中时，直接pip安装时会进到activated的环境中；在base里的时候，会装到 c:myappsanacondalibsite-packages (2.6.0) 里，即anaconda的base环境中；盲猜如果deactivate base了，直接pip会装进系统的python pip pkg里。
