Error: Input files not all in same directory, please supply explicit wd

Question

After trying to build a PDF that worked ~2 weeks ago, no fuss, on a new machine with a fresh install of R, R studio, bookdown, etc, I have this error:

Answer 1

Similar problem: the command Rscript -e "bookdown::render_book(input='index.Rmd', output_format='bookdown::gitbook', config_file='_py-rse.yml')" runs fine from the command-line with bookdown 0.19, but fails with bookdown 0.20 (installed today), giving the message Error: Input files not all in same directory, please supply explicit wd. The configuration file _py-rse.yml (below) does indeed have files in multiple directories - we have to do this because we are building several books in the same project (that share some chapters and appendices). I'll try again with the next update to bookdown; if the bug persists, I'll try to create a reprex.

book_filename: "py-rse"
language:
  label:
    fig: "Figure "
    tab: "Table "
  ui:
    chapter_name: "Chapter "
output_dir: "_book/py-rse"
delete_merged_file: false
