问题
I am trying to view the output of a LaTeX file in Emacs. I am following this guide:
http://www.r-bloggers.com/using-doc-view-with-auto-revert-to-view-latex-pdf-output-in-emacs/
I have done everything they said, but when I run C-c C-c and open the pdf in the other Emacs window, I get nonsense. Preferably, I want the pdf to immediately show in the other window when I run C-c C-c--I do a lot of live texing, and I need to periodically view the output.
Please note that I am running Emacs from the Mavericks command terminal. I have tried every suggest I could find on google and Stack Exchange, but nothing helps. At the moment I have configured my .emacs file as such:
(require 'xpdf)
(require 'ghostscript)
(setq TeX-PDF-mode t)
However, this still does nothing. I am new to Emacs, so any help would be appreciated.
UPDATE: I have also tried M-x doc-view-mode, but it said "no match". Why doesn't doc-view mode work for me?
回答1:
My crystal ball tells me you're using a very old version of Emacs, such as the crappy one that comes bundled with macosx.
Do yourself a favor and install something like http://emacsformacosx.com/ (and make sure you use this one rather than the other one, since you'll still have the old one installed).
M-: emacs-version RET will tell you which version you're using.
