I'm using TeX Live 2015, after the latest tlmgr update --all,
I get the following Error message:
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!
! LaTeX error: "kernel/command-not-defined"
!
! Control sequence \__msg_show_variable:Nnn undefined.
!
! See the LaTeX3 documentation for further information.
!
! For immediate help type H <return>.
!...............................................
l.185 ...riant:Nn \__msg_show_variable:Nnn { Nno }
This is caused by the tikz library hobby. Here is a minimal example:
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{hobby}
\begin{document}
Hallo Welt!
\end{document}
How can I fix this?
