I tried to run the command
jupyter nbconvert --to pdf xxx.ipynb
and I got the error
xelatex not found on PATH, if you have not installed xelatex you may need to do so.
Xelatex does not exist in MiKTeX package manager i tried to get the xelatex package and add it or to update MiKTeX packager manager but always it's not working.
Thanks in advance.
