Answer by Ffisegydd for Error installing package with pip

The $ refers to the beginning of a shell prompt, you shouldn't actually include it in your command :)

So rather than (from the example question you posted)

$ pip install requests

you actually type

pip install requests

In any case, you can download matplotlib .exe files from here for use in Windows. Make sure you get the correct bitness (32bit vs 64bit) and the correct Python version.
