Unable to download as jupyter notebook to pdf

Hello I am very new to python and jupyter as a whole. So while trying to download my my notebook as PDF the following error occurs. Please help me

nbconvert failed: PDF creating failed, captured latex output:
Failed to run “xelatex notebook.tex -quiet” command:
C:\Users\Anuj Makaju\AppData\Local\Programs\MiKTeX\tex/latex\tcolorbox\tcolorbo
x.sty:1241: Undefined control sequence
C:\Users\Anuj Makaju\AppData\Local\Programs\MiKTeX\tex/latex\tcolorbox\tcolorbo
x.sty:1263: Undefined control sequence
Sorry, but C:\Users\AnujMakaju\anaconda3\Library\miktex\texmfs\install\miktex\bin\xelatex.exe did not succeed.

The log file hopefully contains the information to get MiKTeX going again:

C:/Users/Anuj Makaju/AppData/Local/MiKTeX/2.9/miktex/log/xelatex.log

You may want to visit the MiKTeX project page, if you need help.

How did you install MiKTeX? Is it up-to-date?
