It might be helpful to say the operating environment, version of ERPNext and version of wkhtmltopdf that was installed. Why did you install wkhtmltopdf? Was there a tutorial that you were following?

there was no tutorial , i just re installed it because i were have a problem in Download Table as a PDF so i try to reinstall it . i recognize i miss Arguments from this package related to the Frappe framework

I might try bench setup requirements , then bench update

Thank you , i will try it and told you

You should install the version of wkhtmltopdf with the QT patch.

hi @crafter thank you for helping . but the problem here the Frappe miss arguments from wkhtmltopdf not in it`s version or any thing else . so i want to know a way enable frappe to see wkhtmltopdf to avoid this error.

It says in the error message that it requires the version with the Qt patch.

okay thanks i `ll try it and told you

What does wkhtmltopdf -V return?

@AlinYellow this should return something like wkhtmltopdf 0.12.5 (with patched qt). Else you should uninstall this package and run bench install wkhtmltopdfwhich installs it for you.


i used " bench install wkhtmltopdf " , it didn`t work .

Maybe try this :
&& dpkg -i wkhtmltox_0.12.5-1.stretch_amd64.deb && rm wkhtmltox_0.12.5-1.stretch_amd64.deb

Like in this script

PS : be sure to uninstall other versions with something like apt remove wkhtmltpodf

Sincerely yours,
