It's the same way,i do in Scripts folder where pip and conda is placed.
If Anaconda is set in Windows Path,then it will work from anywhere in cmd.

G:\Anaconda3\Scripts
λ pip -V
pip 19.0.3 from G:\Anaconda3\lib\site-packages\pip (python 3.7)

G:\Anaconda3\Scripts
λ pip install stop-words
Collecting stop-words
