# A difficulty to understand a latex error message

I have this error message that I don't understand.

Please if you can help me

• Welcome to LaTeX! Welcome to TeX.SX! Please help us help you and add a minimal working example (MWE) that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – Moriambar Jun 4 '17 at 7:21
• error message starts a bit earlier this is not enough to decode the problem – percusse Jun 4 '17 at 7:38
• latex is trying to input a file it can not find but you have only shown a small fragment of the error message so hard to help. please show the full error from the log from ! in a code block {} not quote so line endings are preserved. – David Carlisle Jun 4 '17 at 8:12
• Just a guess: pst-arrow is a recent package, which was a part of pstricks-add previously. Try 1) updating your installation; 2) installing pst-arrow. – Bernard Jun 4 '17 at 9:09
