Solving "500: Internal Server Error, nbconvert failed: xelatex not found in PATH"

Whenever I try to export a Jupyter notebook as a PDF I get the following error in a separate window:

500 : Internal Server Error
The error was:

nbconvert failed: xelatex not found on PATH, if you have not installed xelatex you may need to do so. Find further instructions at https://nbconvert.readthedocs.io/en/latest/install.html#installing-tex.

I am running macOS Sierra 10.12.6.

Things I have tried:

• Re-installing nbconvert through pip (in the Jupyter notebook) and conda (terminal)
• Installing xelatex for Mac
• Re-installing Mactex
• Installing pandoc (both through pip and through "conda install -c conda-forge pandoc")

Running

!echo $PATH

Yields:

/Users/ed/anaconda/bin:/Users/ed/anaconda/bin:/usr/bin:/bin:/usr/sbin:/sbin
