Installing Pip on Msys | 易学教程

问题

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

AttributeError: 'NoneType' object has no attribute 'bytes'

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.

回答1:

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

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

回答2:

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

Then run the following:

python get-pip.py

For more details refer: https://pip.pypa.io/en/stable/installing/

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.py
python get-pip.py
(ignore the error from previous step)
python -m pip install -U --force-reinstall pip
