Bitbake failing to build

pyraohms — Fri, 07 Jul 2017 19:55:48 GMT

I am trying to get familiar with the Yocto system. I have succesfully followed the latest version of imx yocto project user manual. When i try to execute bitbake core-image-base i get the following:

Traceback (most recent call last):

I can't make any sense out of it....

Never mind. This error (and probably similar ones) was caused by a dirty build environment. A reinstallation of the OS (in my case Ubuntu 17.04) solved the problem.

This problem is caused by a change in the "html5lib" Python package. If you're using an html5lib version > 0.9999999 (seven nines), then you'll see this problem.

The change that causes the problem is that "html5lib.treebuilders._base" was renamed to "html5lib.treebuilders.base".

beautifulsoup, html5lib: module object has no attribute _base - Stack Overflow

Bug #1603299 “Crash with latest html5lib” : Bugs : Beautiful Soup

To fix the problem, you can either:

install html5lib version 0.9999999 (in place of the newer version)

or:

edit sources/poky/bitbake/lib/bs4/builder/_html5lib.py and replace all instances of "html5lib.treebuilders._base" with "html5lib.treebuilders.base".
