Re: [PyX-user] text color problem

Hi, thanks for running the code.

The color package is correctly installed, I think, since I can compile
colored text in latex outside pyx.
I printed the full error, which I report below. It seems that at the end
pyx does not find the pyx.def. I searched it in the HD and I found the file
in the correct folder; however, I think I found the problem, my username
has an accent, and clearly tex interprets that utf8 character wrong:
  ! LaTeX Error: File `*C:/Users/JOS\unhbox\voidb@x \penalty \@M \
{}1/AppData/Loc*
*  al/Temp/pyxeg9r80wk/pyx.def*' not found.

Now, is strange that this happens when latex is run by pyx, but not
normally when compiling a document.

best,
Jose

The expression passed to TeX was:
  \usepackage{color}%
  \PyXInput{4}%
The return message from TeX was:
