当我尝试将jupyter笔记本下载为pdf时，出现“ 500：Internal Server Error”和以下错误消息。有人知道这个问题可能是什么吗？我已经安装了nbconvert，pandoc和miktex。我正在使用python 3.6在Windows 10机器上工作。
错误：
nbconvert failed: PDF creating failed, captured latex output:
xelatex: warning: running with administrator privileges

======================================================================
Sorry, but C:\Users\username\AppDataPython\envs\py36\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/username/AppData/Local/MiKTeX/2.9/miktex/log/xelatex.log
You may want to visit the MiKTeX project page, if you need help.
