问题
I am using emacs 24 on fedora 17. I installed markdown-mode, but whenever I try to export a file by typing C-c C-c m or C-c C-c p in emacs, I got this error:
/bin/bash: markdown: command not found
I read that this is probably an issue with the path variable, so I compared the env variable by typing $ env at the command line and Esc-! env RET in emacs. I found the path variable description is the same in both cases.
What is this error? How can I fix it and execute markdown previews from within emacs?
回答1:
Install any markdown generating tool as you like, for example pandoc.
Then add the following line to your .emacs file:
(custom-set-variables
'(markdown-command "/usr/local/bin/pandoc"))

This error occurs when you do not have a markdown parser installed. Installing one is simple with brew. From the command line:
brew install markdown
This should result in something like:

######################################################################## 100.0%
/usr/local/Cellar/markdown/1.0.1: 2 files, 40K, built in 2 seconds
Before running that command, I had the same error you did. After running that command, which installs a markdown parser on your system, the emacs commands C-c C-c m and C-c C-c p worked as expected by opening an HTML version of my markdown file in either another buffer or the browser, respectively.

You just need to pick and install a markdown parser:
- rdiscount (
gem install rdiscount). - python2-markdown (
yum install python-markdown2) - or some other.
Then, in emacs:
M-x customize-mode RET markdown-mode
Set 'Markdown Command' to the name of the executable you installed -- for example, rdiscount or /usr/bin/markdown2.

You need to setting up the markdown-command, there is a thread about displaying it in github way, through pandoc.
