My question is about packages lwarp and pstricks. I use to work in pstricks for exercises sheets and then converted to HTML page with a little help of lwarp. It worked perfectly.

Two days ago I upgraded my LaTeX distribution (MacTeX Latex 2021 for macOS 10.15.7 Catalina) and I found that I need to add -dALLOWPSTRANSPARENCY in the line of ps2pdf (I use TexMaker). But the problem is when I try to pass file.tex to file.html as I used to do, I have a error message in terminal:

 Last OS error: No such file or directory
Current file position is 588453
GPL Ghostscript 9.53.3: Unrecoverable error, exit code 1

And I have no idea how to fix it. Any help would be welcomed.

  • Hello every one. I have found a solution. I put \lwarpsetup{ HTMLLatexCmd= { latex --shell-escape \jobname_html \LWRopseq dvips -o \jobname_html.ps \jobname_html.dvi \LWRopseq ps2pdf -dALLOWPSTRANSPARENCY \jobname_html.ps } } just under \usepackage[options]{lwarp} and it works. I don't Know if there is another one, in that case, please, write it. Thanks Apr 13, 2021 at 15:05

Instead of the latex->dvips->ps2pdf route, you can run the PSTricks code with lualatex. Then you do not need GhostScript. Must have an up-to-date TeX 2021
