Hi. I was instructed to use tinytex for pdf on a Macintosh. Didn't work. So I used MacTex, following the instructions here: Install R, RStudio, and TeX (Mac). That worked.
But when I moved to my main project directory from my little test area, once again I couldn't output pdf. It was trying to output _main.pdf and failing. I renamed _bookdown.yml and _output.yml to _bookdownxx.yml and _outputxx.yml. Then it worked.
This can't be the recommended way of outputting pdf in a bookdown project. What's going on?
