%pycodestyle_on and %flake8_on produce errors

I've recently installed pycodestyle-0.5 on a number of linux systems (Ubuntu and Gentoo), installed with pip and on all of them cannot use the auto-checking commands: %pycodestyle_on and %flake8_on.

%pycodestyle_on gives the error:

Error in callback <bound method VarWatcher.auto_run_pycodestyle of <pycodestyle_magic.VarWatcher object at 0x7f742c0687f0>> (for post_run_cell):

TypeError Traceback (most recent call last)
TypeError: auto_run_pycodestyle() missing 1 required positional argument: 'result'

as soon as it is invoked, and then in any cell that is executed. %flake8_on produces a similar error.

I have pycodestyle-2.3.1 and python-3.6.

Hmm, I cannot reproduce this one.
What is your IPython version?

The flake8_on and pycodestyle_on magic functions use the post_run_cell event callbacks that were added in IPython 6.3.

If I do the following in a notebook cell:

!ipython --version

I get: 7.5.0

Ah sorry - that does appear to be my problem. All of these systems appear to have ipython 5.x.

Thanks!

No problem, glad you solved it!
