pip install accepts --> fails

Question

I'm trying to pip install accepts, but the code fails. Before the red text of the error (which just says the path of the error pretty much), there is: "TypeError: 'package' must be a string (dot-separated), list, or tuple"

I have already pip installed this on a different computer but for some reason this error pops up in my home computer. Does anyone know how to solve this? Note: I have pip installed other modules on my computer, this specific module returns the error.

Edit: I've been trying at this for a while, even went to the creator's github (https://pypi.python.org/pypi/accepts/0.0.2). At this point I tried manually downloading the library which also didn't yield a result. It'd be really helpful if someone could pinpoint me in a direction. Thanks.
