Broken Pip

RKarim · 2021-11-29 20:00:26

After updating my system, Pip no longer functions. When attempting to install a package the following occurs:

Defaulting to user installation because normal site-packages is not writeable

I have been unable to find any information about this error online, nor understand it myself. I have reinstalled 'python-pip' to no avail, I've also reinstalled 'python' itself. Help would be appreciated.

Thanks,
RK

Unrelated to your issue, but you are mixing up system and locally installed pip packages. Don't do that.

evilcrash · 2021-11-29 22:05:30

You aren't the only one, fortunately. I'm getting the exact same output of any pip install and I just installed pip myself. I'm relieved to know this is isn't something on my end, but I still want a solution.

pfunkman · 2021-11-30 03:51:25

I would try updating again. I had the same problem after updating this morning, but it was resolved after updating again this evening. More specifically, I believe it was updating python-cachecontrol to 0.12.10-1 that caused the problem, and a further update to 1:0.12.6-1 that fixed the problem. It's likely this issue https://github.com/ionrock/cachecontrol/issues/262 , so I guess any version greater than 0.12.6 could be affected.

evilcrash · 2021-11-30 21:18:05

I can verify a quick pacman -Syu fixed the problem.

ehrichweiss · 2021-12-04 01:46:35

I have already done a pacman -Syu but the problem persists for me. Anyone have any insights?

I wasn't very thorough in my initial "it works" so I'll try to go in-depth: I noticed the problem, shut down my computer, and read pfunkman's message the next morning. I turned it back on, ran pacman -Syu, and reinstalled pip including its dependencies. My distribution is also EndeavourOS, if that changes anything.

It must matter because I'm using Arch/Artix and still getting it. I've done everything from reinstalling pip, to downgrading a good portion of python(or at least anything mentioned in the error), and still get the error. There's gotta be something I'm missing but I'll be damned if I know what it is.

Neither EndeavourOS nor Artix Linux are supported here. If you are having issues with either of those distributions, please seek support from their respective support channels.

ehrichweiss · 2021-12-04 23:35:00

I figured that since some of my repositories are actually Arch, that it would apply as well. I won't make that assumption again I guess.

For the record,

Here's my diff for /usr/lib/python3.9/site-packages/cachecontrol/controller.py that seems to be a temporary workaround...

I can confirm that this fixes the issue for me. Updating or rolling back did not.
God-knows where you found this quickfix. But I am grateful that you did.

I understand your frustration with copious amounts of users from other distros coming in and requesting a fix.
Believe it or not, but Artix resources see their own share of people coming from other distributions. Without disclosing it! And then later on it turns out that their distro isn't even Arch-based! Had a guy with a RedHat and systemd asking for fixes in there the other day. Only he didn't say that he had either of those.

So please. Allow for the people to congregate in here. I, too, am an Artix user.
But I was able to find people with the same issue in here, on Arch forums. And - thanks to this forum - I was able to fix my issue.
But of course, it is very important that users disclose it beforehand - that they aren't on Arch.

Our position is that everyone is welcome in these forums and may participate whether or not they are using Arch Linux -- But.... We cannot and will not provide support for non-Arch systems. This includes anything that is not an Arch fork, it includes everything that is an Arch fork, and it includes anything that was installed in accordance with third party installers, scripts, youtube videos, or random blogs. The reason for this is that we do know what decisions were made in the installation. What is more important, the person seeking help does not know what decisions were made in the installation of their system (they did not make them, and they did not follow our guidance). We cannot and will not study every random installer, video or guide to figure it out. We will (firmly) direct such users to take their support questions to the developer of whatever it was they used.

As an Artix user, please, feel free to contribute to threads. Same goes for users of Gentoo, Slackware, Fedora, Arch Linux Arm, etc.... Insight from other distributions is useful. But, provide disclosure: "I am using Artix, and had the same problem. I fixed it by...". In this way a valid data point can be introduced without confusing things (and users) if Artix requires a different method of configuring something; or if the fix is not relevant to Arch because of the use of different libraries (for example).

Thank you for these words. They clarify things quite a bit, as well as show me that I mistook a suggestion for a demand of sorts.
I appreciate your position. A lot!
I will bear in mind that the first thing I say when requesting support should be an indication that I'm not on Arch.
And I understand your reasons for this perfectly well. Thank you for taking the time to explain everything.

P. S. And sorry for bumping. Seems like a resolved thread by now, really. But I just didn't want to leave you hanging, after you've replied to my post.
