I have tried to reinstall the MacTex twice. I even reinstall R and RStudio. Nothing could cure this problem. Please Help me, I'm in middle of my thesis and I need to use Knitr and RStudio is only easy and suitable place for me to work in.

The output for

which pdflatex
echo $PATH

    This question appears to be off-topic because it concerns a bug in a beta version of Mac OS X and is unrelated to (La)TeX and friends. – Paul Gessler Sep 12 '14 at 2:19
  • I would also like to note that during the "middle of one's thesis" is probably not the best time to be testing an experimental operating system. :-) – Paul Gessler Sep 12 '14 at 3:21

R, rstudio and latex all are in there latest version. I think the problem is in OS X yesomite beta. I downgrade the system. It is working fine now.

Thank you for your responses.

    Yosemite beta has a significant bug in passing environment variables to subprocesses (duplicate/incorrect PATH, for instance). – Adam Maxwell Sep 5 '14 at 23:39
