Installing Pip on Msys

Question

I have built a simple PyGTK app using Python 3.5.2 and Msys but I need some modules not in the default installation, and although I could use setup.py install to get them I would much rather use pip.

I looked around and found this but it relates to Python 2 and gave an error when attempting to follow the instructions given:

$ python3 getpip.py

and I tried the way one would install pip on Linux:

pacman -S python2-pip           
pacman -S python-pip           

as listed here, as well as:

pacman -S python3-pip

but each time I got a error: target not found: error.

Surprisingly I couldn't find anything else.

So how do I get pip on Msys?

Thanks.

FYI github.com/Alexpux/MSYS2-packages/issues/889 – Collective

@Collective I know it doesn't come with pip and that page confirms it. I to know if there is a way to install it separately. – Headmost

Answer 1

Please note that at this time the following command is now working on msys2:

$ pacman -S python3-pip
$ pip3 install --upgrade pip

Eddra

You are right. I recently updated my MSYS2 installation and this worked a treat, thank you :) – Headmost

This is working, but installs a new Python executable, without the GTK libraries. How can I have both GTK and Pip with the same Python executable? – Na

Installing through pacman and then upgrading through pip is a bad advice; the later effectively corrupts the pacman pip package, causing future pacman -Syu to fail (if the pip was actually updated). Instead, either stick to using the version from pacman, or install pip entirely without pacman (see other answers).\ – Gourami

Answer 2

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:

1. curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
2. python get-pip.py
3. (ignore the error from previous step)
4. python -m pip install -U --force-reinstall pip

Answer 3

To install pip, securely download get-pip.py.

Then run the following:

python get-pip.py

OP is already using getpip.py, and Python 3 seems to be a requirement. I'm not sure your copy/paste is helping here :/ – Album

In msys2, the pip is not installed as part of the default packages when python is installed (The version of python installed is 3.6.2). Installation using the pacman did not yield any result was getting error: target not found: error. So downloaded the file manually from location to install pip (9.0.3). – Condense
