open command prompt type: pip install pyperclip

if this doesn't work then do this use cd Python35/Scripts to get to the scripts folder This is the folder where pip is located.

Now type: pip install pyperclip

This will download and install pyperclip

now type: pip freeze

And pyperclip should be listed

If you want to test in python shell remember to close the shell(if open) and open new one because it needs to load the new package.

type in python shell: import pyperclip

it should accept it and now you can pyperclip.copy() and pyperclip.paste()

Good luck!
