Jekyll - Liquid Exception: Unknown operator forloop

Question

I've updated jekyll and now get this error:

Liquid Exception: Unknown operator forloop in collection.html

Here's the code in question:

{% for tag in site.content_data.tags %}{{ tag }}{% if not forloop.last %}, {% endif %}{% endfor %}

How would I resolve this error?

Answer 1

I suspect your {% if not forloop.last %} is not the valid syntax, as I don't see it in the operators section .

Have you tried {% if forloop.last == false %} ?

Answer 2

不要与易曾相矛盾，但你也可以用以下方法解决这个问题：

{% unless forloop.last %}something{% endunless %}
