title: When trying to save R Markdown file, "Error file not found" pops up
body: <p>I am very new to R so if someone could explain this to me in very simple words, it would be greatly appreciated.</p>
  <p>I just completed a project in r markdown but when I am trying to knit it, &quot;Error file or directory not found&quot; pops up and I cannot open the file even if it is saved manually.</p>
  <p>this is what pops us in my console</p>
  <pre><code>processing file: Bellabeat-project.Rmd

  No LaTeX installation detected (LaTeX is required to create PDF output). You should install a LaTeX distribution for your platform: https://www.latex-project.org/get/
  
    If you are not sure, you may install TinyTeX in R: tinytex::install_tinytex()
  
    Otherwise consider MiKTeX on Windows - http://miktex.org
  
    MacTeX on macOS - https://tug.org/mactex/
    (NOTE: Download with Safari rather than Chrome _strongly_ recommended)
  
    Linux: Use system package manager

  <p>I've tried saving other r markdown files and it worked perfectly so I am unsure what the problem is</p>
  <p>I have also installed everything that is being said in the error window but it still doesn't work</p>
