Hello,
I also encountered this problem, and I refer to #8 (comment) install latex with command pip install latex and install latex app (MacTex) in this link, but the problem still exists.
After checking, this is because the latex binary program cannot be found in the new environment PhySO created by Conda. Please check if there is a latex binary in your PATH in the virtual environment PhySO with the following commands:
conda activate PhySO
echo $PATHIf not, use the following command to add it in MacOS:
export PATH=/Library/TeX/texbin:$PATHHi @Qixin913, can you confirm that you were able to resolve your issue installing latex so I can close this thread ?
