# l3kernel could not be found

I was hoping to use packages which uses LaTeX3e, so I did the following:

\documentclass{standalone}
\usepackage{l3kernel}
\begin{document}

\end{document}


where I have got this error:

! LaTeX Error: File l3kernel.sty' not found.

Type X to quit or <RETURN> to proceed,
or enter new name. (Default extension: sty)

Enter file name:
! Emergency stop.


I suspect if my installation did wrong at some point, meanwhile I am using

• TeX Live 2016 (portable)
• Windows 7
AFAIK, there is no such LaTeX package l3kernel.sty for use in \usepackage. But there is a CTAN/TeX distribution package "l3kernel", bundling LaTeX packages like expl3.sty, l3*.sty packages and a class l3doc.cls.
• @SHY.John I have no idea, what you want to do. If you want to use a package, which requires LaTeX3, then just load the package. An example is siunitx, which uses expl3, xparse, and l3keys2e. But the user just loads it by \usepackage{siunitx}. – Heiko Oberdiek Sep 17 '16 at 7:49
• Emm... I've loaded siunitx at first. – SHY.John Sep 18 '16 at 11:04
• @SHY.John Why do you want to load l3kernel? Package siunitx` already loads the packages, which it needs. – Heiko Oberdiek Sep 28 '16 at 17:16
