Error with pip

I need to install pyinstaller for Python 2.7 but it is not working. It worked for Python 3.4, but in this case I need it for python 2.7.

C:\Python27\Scripts>pip install pyinstaller
Collecting pyinstaller

I keep on getting this error. It goes away when I use Python 3.7 but I want to use it for python 2.7. I cannot install anything with pip without getting this error. Does anyone know another way to get pyinstaller for python 2.7 or how I should fix pip?

Try this command with your package name:

pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org <any package name>

Thanks for the advice. I was able to get pyinstaller installed by upgrading python27. It looks like it is working for now.
