! Undefined control sequence.
l.4387 \ProcessPgfPackageOptions
{/forest/package@options}. 

But this doesn't happen when I use TeXWorks (with MikTeX) to compile the document. Any idea why? The following simple document shows the problem:
\documentclass{article}

\usepackage{forest}

\begin{document}

\begin{forest}
[root[child1][child2]]
\end{forest}

\end{document}

The command \ProcessPgfPackageOptions is defined in newer version of pgfopts.sty package.
Which is updated in version 10.10, revision 2013/06/27.
Just check that you use package from recent enought repository.
Or you can of course update this package directly from CTAN.
