Created attachment 402120 [details] files matching winreg substring I use pychecker to check my python code. Recently, it started to print ImportError during importing itself or its required modules this: $ pychecker mytool.py Processing module mytool (mytool.py)... warning: couldn't find real module for class <class 'cElementTree.ParseError'> (module name: cElementTree) warning: couldn't find real module for class <class 'fftpack.error'> (module name: fftpack) warning: couldn't find real module for class <class 'lapack_lite.LapackError'> (module name: lapack_lite) warning: couldn't find real module for class <type 'mtrand.RandomState'> (module name: mtrand) warning: couldn't find real module for class <type 'mtrand.RandomState'> (module name: mtrand) warning: couldn't find real module for class <type 'cntr.Cntr'> (module name: cntr) ImportError: No module named _winreg The warnings have always been there as far as I remember.

What's in mtool.py?

I see the same, though I don't know what it is.
+*six-1.9.0-r1 (06 May 2015) + + 06 May 2015; Justin Lecher <jlec@gentoo.org> +files/six-1.9.0-winreg.patch, + +six-1.9.0-r1.ebuild, metadata.xml, six-9999.ebuild: + Backport fix for windows only modules, bug #547928 + So this one was a six problem. I still see additional import problems. How about you?
I also asked at [Matplotlib-users] ImportError: No module named _winreg and the only hint I received is from Thomas Caswell: <quote> winreg looks like it is for programmatic access to the windows registry which mpl uses to find fonts in windows (https://github.com/matplotlib/matplotlib/blob/master/lib/matplotlib/font_manager.py#L173). I suspect this is a problem with pychecker being too enthusiastic about checking imports. </quote> I think it is either due to recent six package update or matplotlib. I cannot test now on my live system.
(In reply to Martin Mokrejš from comment #7) > I think it is either due to recent six package update or matplotlib. I > cannot test now on my live system. It was in six which I backported the fix for in six-1.9.0-r1.
