Emacs markdown-mode error on preview: "bin / bash: markdown: command not found"

Question

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?

Solution 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"))

Solution 2

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:

==> Downloading http://daringfireball.net/projects/downloads/Markdown_1.0.1.zip
######################################################################## 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.

Solution 3

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.

Solution 4

• Add emacs package repository to init.el:

(require 'package)
(add-to-list 'package-archives
             '("melpa-stable" . "https://stable.melpa.org/packages/"))
(package-initialize)

• Refresh packages:

M-x package-refresh-contents

• Install emacs major mode markdown-mode by evaluating:

M-x package-install RET markdown-mode RET

• Install markdown processor for your operating system:

brew install pandoc
#OR
sudo apt-get install pandoc

• Verify pandoc installation:

which pandoc
# returns /usr/local/bin/pandoc

• Map the markdown parser in init.el:

(custom-set-variables
  '(markdown-command "/usr/local/bin/pandoc"))

Solution 5

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