What should I do? Reinstall pip? pip-scripts.py file, is not any more in the directory, I don't know what happened.
Can't install/uninstall other modules. How can I fix it? I am using windows 7.

I think you don't have any special reason to use python 2.7. So I suggest you remove python 2.7, download and install python 3.5 and start using it! As they say: Python 2.x is legacy, Python 3.x is the present and future of the language. Read more.
