_NamespacePath object has no attribute sort (31.0.0) #885

jkbbwr · 2016-12-12T11:50:15Z

When pip installing a package that shares a namespace it fails out on 31.0.0 but installs fine on 28.8.0

tseaver · 2016-12-12T17:14:49Z

From what I can tell, this is a 3.5-only failure.

hciudad · 2016-12-12T23:09:31Z

I can trigger the error just by importing setuptools. However, when I do it a second time, it imports fine. So, if I do something like this, the install succeeds.

try:
    from setuptools import setup, find_packages
except AttributeError:
    from setuptools import setup, find_packages

jaraco · 2016-12-13T00:48:22Z

I tried adding a test to capture the failure, but the test is passing. So to some extent it's working. Why is the test working but your package not?

tseaver · 2016-12-13T01:16:55Z

@jaraco The bug happens trying to import setuptools/pkg_resources in an environment where a namespace package is installed, but where there is more than one directory in the path of the namespace package (e.g., one package in a "development install" vs. dependencies installed into site-packages).

In @jkbbwr's case above, what would cause zope.__path__ to be an instance of _NamespacePath rather than the plain list that the code in pkg_resources._rebuild_mod_path clearly expects? That class appears only to be instantiated by the stdlib's import machinery under Python 3.5+:

importlib._bootstrap_external._NamespaceLoader.__init__
importlib._bootstrap_external.PathFinder.find_spec.

As a hackaround, one might add monkeypatch a sort method onto importlib._bootstrap_external._NamespacePath. ;)

…e. Ref #885.

jaraco · 2016-12-13T02:19:37Z

I've just pushed another commit, this one in the test_develop module. This test does as you describe, installs one package into a simulated site-packages (myns.pkgA) and another using develop (myns.pkgB). Both packages are importable and pkg_resources can still be imported as well.

jaraco · 2016-12-13T19:04:55Z

what would cause zope.__path__ to be an instance of _NamespacePath rather than the plain list that the code in pkg_resources._rebuild_mod_path clearly expects?

It's almost certainly the fact that the new -nspkg.pth files are using importlib.util.module_from_spec to initialize the module (and thus setting __path__).

I continue to be unable to replicate the error indicated. Here's one such attempt:

What steps do you have to invoke to get a virtual environment that replicates this issue?

theacodes · 2016-12-13T20:30:16Z

This is also occurring consistently over at https://github.com/GoogleCloudPlatform/google-auth-library-python in our lint tox (sample failure).

It'll also occur in other tox environment if you run them twice. The first time tox creates the environment from scratch, but when it tries to re-use an existing environment it 'splodes.

Let me know if I can do anything else to help reproduce/fix this.

jaraco · 2016-12-13T22:05:53Z

Excellent. That does help. I simply checked out GoogleCloudPlatform/google-auth-library-python and ran tox -e lint and that replicated the failure. I should be able to distill the issue from there. Thanks.

theacodes · 2016-12-13T22:06:25Z

Awesome. 👍

warsaw · 2016-12-13T23:18:09Z

I just hit this same problem. I can craft a reproducer if you need it. I see it when running tox on a py35 environment with flufl.i18n, which uses flufl.testing, both of which are namespace packages. I need to commit and push a fix to the latter for you to reproduce it. Let me know if you need it, but it would be really great to get a quick fix released for this bug.

warsaw · 2016-12-13T23:21:10Z

FWIW, it affects Python 3.6 also; I can't test 3.4.

jaraco · 2016-12-14T02:01:47Z

Working with the google-auth library, I find that if I set usedevelop = True in the tox settings, the issue doesn't occur. This behavior indicates to me that the issue lies in part with a package which is duplicately installed. In any case, I was able to use it to create a test case that captures the error.

warsaw · 2016-12-14T02:08:21Z

@jaraco That's interesting because I have usedevelop=True and it happens for me. But at least you ahve a reproducer. :)

theacodes · 2016-12-14T02:08:26Z

usedevelop probably won't work except in that specific case because google-auth uses namespace packages.

jaraco · 2016-12-14T02:14:31Z

@jonparrott: The whole point of v31.0.0 and the fix for #250 is that 'develop' and namespace packages should work well together now, so I hope you can drop that assumption soon.

@warsaw: The fix is in place. Can you update setuptools in your test environment to git+https://github.com/pypa/setuptools@3943cf4 and see if that addresses the manifestation you encountered?

jaraco · 2016-12-14T02:20:40Z

Well hell. The fix works for Python 3.6 but not for Python 3.5. Thanks to Travis for catching that.

#885.

jaraco · 2016-12-14T02:45:34Z

Okay. Yet another version to test against, this one passes on Python 3.5. git+https://github.com/pypa/setuptools@7c0c39ef. I'm not happy with the fix, but it passes the tests.

I've unlocked the conversation here. Others have pointed out that there are other ways users can encounter this issue, so might as well make this issue a wiki about the ways people can encounter the issue and how they worked around it.

dimon777 · 2018-04-22T18:01:59Z

It is still a problem on Ubuntu 16.04. It is easy to simulate it with
apt install python3-pip
apt install glances
then trying to run glances gives above error. After reading all these long threads it is not clear how this has to be fixed. I also noticed apt, pip and pip3 all install packages into different locations. So far I have:

/usr/lib/python/python2.7/
/usr/lib/python/python3/
/usr/lib/python/python3.5/

/usr/local/lib/python2.7/
/usr/local/lib/python3.5/

Why is there such a mess after one is using standard routines to install packages (either apt or pip) ?!

jaraco · 2018-04-22T18:52:53Z

I'm unable to replicate your findings:

$ echo "from ubuntu:xenial\nrun apt update\nrun apt install -y python3-pip\nrun apt install -y glances\nRUN glances -V" | docker build -

(also running simply glances in an interactive terminal works).

Why is there such a mess?

Setuptools fixed this in 31.0.1. Pip incorporated the fix in 10.0.0b1. venv still pulls in older setuptools versions. Downstream package managers may not have pulled in these fixes.

Hi, is there a fix/workaround for this? I am getting the "sort" error even when I try pip3 --version, I also can't uninstall setuptools and/or update it (as some of you suggested).

I am using a mac High Sierra.

Try this workaround:

I had the same problem using poetry.

Running

poetry run pip install --upgrade pip setuptools

instead of

pip install --upgrade pip setuptools

fixed the issue.

on certain distros, buggy pip and setuptools are used, so we need to upgrade them first. see also: googleapis/google-cloud-python#2990 and pypa/setuptools#885 Signed-off-by: Kefu Chai <kchai@redhat.com>
