AttributeError: 'NoneType' object has no attribute 'pattern' #108

Travis CI is falling for me in another project because of

$ python -m pylint lowfat

Any suggestions of what can be causing it?

What version of pylint are you using? I had similar issue with the latest pylint==1.8, and pylint-django doesn't seems to compatible with latest pylint.

Try to downgrade the pylint, and then test it

rgaiacs · 2017-12-18T15:18:50Z

I try to downgrade pylint to a early version but I encounter other problems. Thanks for the help. Feel free to close this issue.

christianmlong · 2017-12-18T18:35:11Z

Downgrading to pylint 1.7.5 fixes it for me.

pip install 'pylint>=1.7,<1.8'

pylint              1.7.5
pylint-django       0.7.2
pylint-plugin-utils 0.2.6

Python 3.6.3 installed via Homebrew.

pcharasala · 2017-12-18T21:12:52Z

I have the same issue.
My Pylint is Pylint 1.8.1

pcharasala · 2017-12-18T21:19:38Z

@christianmlong Thank you somuch!
I have been struggling since morning. Finally your hint helped me.

renatoliveira · 2017-12-18T22:39:50Z

While downgrading to pylint 1.7.5 temporarily fixes this issue, it does present other errors (like pylint-dev/pylint#1609 which are fixed with pylint 1.8+ I believe).

I have a project that is using Django 2.0 and I've been using pylint-django with it. Some days ago I configured Travis CI and today when I added pylint to the command list I found this very issue. 😉

Build log can be found here: https://travis-ci.org/renatoliveira/notto/builds/318305203

Using:

Python 3.6.3 (64-bit) on Windows 10
Pylint 1.7.5
Pylint-django 0.7.2

When Pylint is upgraded to 1.8.1, I get the AttributeError mentioned by @rgaiacs as well.

When can we expect a fix for this? Had to update pylint and just got caught by this

hajotka · 2018-01-05T22:33:49Z

I'm also affected by this issue. Going back to 1.7.5 causes other issues as mentioned above.

pylint-dev/pylint-django#108

This updates the following packages: - faker from 0.8.7 to 0.8.8 - django-extensions from 1.9.7 to 1.9.8 - flake8-commas from 0.4.3 to 1.0.0 - flake8-quotes from 0.12.0 to 0.13.0 - setuptools from 38.2.3 to 38.4.0 To avoid a bug in pylint-django (caused by changes in the new minor releases of pylint and astroid), pylint and astroid versions are pinned to the last safe versions. pylint-dev/pylint-django#108 Finally, all versions of Django 2.0 have the alpha version removed, creating ranges for only stable versions. Django 2.0 is used when building documentation instead of Django 1.11.

if anyone else is struggling with this, jambonrose pointed me in the right direction with his commit (jambonrose/django-improved-user@4efdea7)

Upgrade to pylint==1.8.1 causes AttributeError: 'NoneType' object has no attribute 'pattern'.
Upgraded astroid==1.6.0 causes the Unused variable '__class__' (unused-variable) error.

You'll need to pin/downgrade both to have a working environment:

astroid==1.5.3
pylint==1.7.5

hajotka · 2018-01-19T08:04:05Z

@atodorov : Awesome! Any idea when the next release will come?

atodorov · 2018-01-19T08:17:28Z

@hajotka very soon. Maybe even today.

ecstaticpeon · 2018-04-23T15:19:06Z

@atodorov Hello, the issue seem to have come back in 0.11 with Pylint 1.8.4 or even 1.8.2. Version 0.10.1 is fine.

atodorov · 2018-04-23T20:07:44Z

@ecstaticpeon open a new issue for that with the code that reproduces it.

ecstaticpeon · 2018-04-24T12:55:56Z

@atodorov Actually it looks like it was something else in my environment. Sorry for the false alarm!
