Installing Pip on Msys
Please note that at this time the following command is now working on msys2:
$ pacman -S python3-pip
$ pip3 install --upgrade pip
To install pip, securely download get-pip.py.
Then run the following:
python get-pip.py

The accepted answer installs a new Python exectuable with pip, but without GTK support.
In order to install pip support to the existing GTK Python executable, after encountering that error, we need to run:
python -m pip install -U --force-reinstall pip
(taken from this issue)
To summarize the steps required to install Pip support to the GTK-Python executable:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.pypython get-pip.py- (ignore the error from previous step)
python -m pip install -U --force-reinstall pip
