When filing a bug report, please check the boxes below to confirm that you have provided us with the information we need. Have you:

• [ ] formatted your issue so it is easier for us to read?

• [ ] included a minimal, self-contained, and reproducible example?

• [ ] pasted the output from xfun::session_info('rmarkdown') in your issue?

• [ ] upgraded all your packages to their latest versions (including your versions of R, the RStudio IDE, and relevant R packages)?

• [ ] installed and tested your bug with the development version of the rmarkdown package using remotes::install_github("rstudio/rmarkdown")?

My rmd file is

pythonpath <- file.path("", "../py312/bin/python3.12")
rmarkdown::render(input = "rmdbug.Rmd", intermediates_dir = "/home/user")

When I excute it, R report the error: Warning messages: 1: In dir.create(dirname(dest), recursive = TRUE) : cannot create dir '/home/user/../py312', reason 'Permission denied' 2: In file.create(to[okay]) : cannot create file '/home/user/../py312/bin/python3.12', reason 'No such file or directory'

Seems that use "../" ("../py312/bin/python3.12") in file.path with intermediates_dir confuse Rmarkdown. This error disappears when I remove the option intermediates_dir = "/home/user" or when I remove "../" from "../py312/bin/python3.12" in file.path
