Warning "Directory already exists" when knitting Rmds after the first time

[AshesITR]

This line unconditionally tries to create the temporary pandoc library directory, which persists after knitting one Rmd from within PyCharm.
This results in a warning being displayed on every knit operation.
Guarding this clause with if (!dir.exists(library_path)) will prevent the warning, leading to cleaner console output.

dir.create(library_path, recursive = TRUE)
