Unknown options for package siunitx

Question

I'm getting an error when I try to specify an option with the siunitx package. I have the following line in my preamble:

\usepackage[load-configurations=si-abbr]{siunitx}

And I get the following error:

! LaTeX Error: Unknown option `load-configurations' for package `siunitx'.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
 ...                                              

l.3894 \ifx
           \@empty\si@emulate\@empty\else
? H
The option `load-configurations' was not declared in package `siunitx', perhaps
 you
misspelled its name. Try typing  <return>  to proceed.

I'm not sure which version of siunitx I have; I installed it via the texlive-* packages in Ubuntu 10.04 (Lucid). If somebody could point me in the right direction I would greatly appreciate it.

Answer 1

You have version 1 of siunitx installed, and are mixing version one option values (abbr) with version 2 key names (load-configurations). You want

\usepackage[alsoload=abbr]{siunitx}

In general, you should check the installed documentation for a package on your local system by typing

texdoc <package-name>

at the Terminal. This will give you the relevant options for the version you have.
