Pip Install hangs

Question

I currently have Python 3.5 on my Windows machine. I'm trying to install a Python package using the command "pip install" but as soon as I hit enter nothing happens. The action hangs for such a long time and when I try to exit the command line, it freezes. How do I get pip install to work?

A note to future visitors of this thread: first check the output of `pip -v install `, maybe it doesn't hang, just takes unusually long (but actually does stuff in the background) -- this was the case for me. — martonbognar, Apr 11 '18 at 13:28

If you are you using WSL2, indeed it could be related to pip trying to connect to an XServer. If so, clearing the DISPLAY environment variable first before running it may help:

export DISPLAY=
pip install <packagename>

(Or, as a one-liner: DISPLAY= pip install <packagename>)

do you mean like this: `export DISPLAY= pip install django` ? – flyingduck92 Oct 12 '21 at 11:23
@flyingduck92 run the two commands separately. The export command just sets the DISPLAY environment variable to an empty string – chris Oct 13 '21 at 00:24

If you're using Ubuntu via WSL2 on Windows, it might not work outside a virtualenv. python3 -v -m pip install ... showed me that it was hanging on some OS X keychain import... Hopefully this helps someone else.

uh yes, start your xserver! – pscheit Jul 15 '21 at 03:39
@pscheit would that fix it? – James M. Lay Jul 15 '21 at 16:35

@JamesM.Lay yep this was my issue. It was waiting for a connection to the x server (i guess to show the prompt for the keychain password) – pscheit Jul 17 '21 at 02:37

As another workaround, you can temporarily disable that prompt with `unset DISPLAY`. – Isaac Dec 31 '21 at 12:03
whoa, that's wayyy simpler. – James M. Lay Dec 31 '21 at 22:57
This work for me too, **but WHY????** I'm using X410 as an Xserver. Before that I tried `Pip`, `PDM`, `Pyenv` and Poetry with ` list` to list installed packages and took between 90 and 120 seconds – jocerfranquiz Jan 23 '22 at 22:36
that's a real WTF imo - it should prompt on the command-line instead of opening a window on some display. thanks for your help! – aurora Jan 26 '22 at 11:03
`unset DISPLAY` is cool! – prehistoricpenguin Feb 22 '22 at 01:44

I had to start 'Xlaunch' display server and it worked, according to a @pscheit it was waiting for a connection to x-server and launching one fixed it

pip install something was hanging for me when I ssh'd into a linux machine and ran pip install from that shell. Using -v from above answers showed that this step was hanging

import 'keyring.backends.macOS' # <_frozen_importlib_external.SourceFileLoader object at 0x7f3d15404d90>

This popped up a keyring authentication window on the linux machine's desktop, waiting for my password. Typing my password allowed this to progress.

I have no idea why a macOS package was being imported on a linux machine.

Try using pip programmatically like shown below.

import pip

pip.main(['install', 'the_package_you_want_installed'])

Mellester's solution worked for me.
I had trouble using pip list. The output would just hang until i started a Xserver.
