Liquid Exception: Liquid syntax error (line 170): Unknown tag 'elif' in xyz for markdown 代码块

Liquid Exception: Liquid syntax error (line 170): Unknown tag 'elif' in xyz for markdown code block

我使用 Jekyll 创建我的静态网站。我的降价之一具有以下代码块

....
```yaml
# Example pillar 'packages' YAML
{% if grains['os'] == 'RedHat' %}
apache: httpd
git: git
{% elif grains['os'] == 'Debian' %}
apache: apache2
git: git-core
{% endif %}
` ` `
...

但是网站生成失败

Liquid Exception: Liquid syntax error (line 170): Unknown tag 'elif' in

我如何正确地转义 "code" 它被正确呈现而不被解释为代码。

... any liquid or liquid-like code will be displayed as is.
