[orgmode] plugin seems to fail when using BEGIN_SRC block

Here is the output I am getting when trying to run nikola auto.

* Setting up Docker locally

For Arch Linux users, installing =docker= takes only one command.

#+BEGIN_SRC
sudo pacman -S docker
#+END_SRC

Using emacs version 26.2 and tried using 25.1. org version 9.2.3 used.

I don’t use orgmode, but a quick Google search suggests you may need to specify a language for that source block.

[Binary-Eater]

@Kwpolska noticed that too and thanks for the update.

If I specify the language, I can compile my org file but run into this error in the html render.

zsh:1: command not found: pygmentize

Also, I was hoping not to need to specify a language for blocks that would have things like directory structures. The above snippet isn't my actual org file I am writing but one that reproduces the error.

zsh:1: command not found: pygmentize

Make sure pygmentize is available on $PATH. It comes from the pygments pip package.

Pygments supports a text language, but I don’t know if org-mode doesn’t do any filtering before the language name reaches Pygments.

[Binary-Eater]

@Kwpolska you are right. The language specifier is mandatory.

Mandatory for live code blocks. It is the identifier of the source code language in the block. See Languages, for identifiers of supported languages.

New to org myself. Would be nice to see if the org-mode plugin can throw a nicer exception for this error.

[Binary-Eater]

which pygmentize          
/usr/bin/pygmentize

Installed pygmentize as an Arch package and /usr/bin should be referable?

[Binary-Eater]

Just tested on another setup though and seems to be working fine with pygmentize. Going to close this issue since this seems to be more of an environment setup related issue. Thanks again @Kwpolska
