python - How to downgrade the installed version of 'pip' on windows?

Question

On a windows 7 machine I have pip version 1.5.6 installed:

pip 1.5.6 from C:UsersdietzPNCasENVlibsite-packages (python 2.7)

In order to find the reason for an error I want to install a different version of pip, which worked fine for me. So how can I uninstall pip and install version 1.2.1 instead?

Answer 1

pip itself is just a normal python package. Thus you can install pip with pip.

Of cource, you don't want to affect the system's pip, install it inside a virtualenv.

pip install pip==1.2.1
