Javascript 将容器div添加到Jade mixin

我试图在keystonejs的后期混合中添加一个名为.desc的h2&p标记。但每次我添加此项时，都会出现以下错误：

Sorry, an error occurred loading the page (500)
blog.jade:5
3| mixin post(post)
4| .post(data-ks-editable=editable(user, { list: 'Post', id: post.id }))
>5| .desc
6| h2.entry-title=post.title
7| p.lead.text-muted.entry-utility Posted
8| if post.publishedDate

Invalid indentation, you can use tabs or spaces but not both

我正在尝试将.desc包装添加到内容：

mixin post(post)
.post(data-ks-editable=editable(user, { list: 'Post', id: post.id }))
    .desc
        h2.entry-title=post.title
        p.lead.text-muted.entry-utility Posted
            if post.publishedDate
                | #{post._.publishedDate.format('MMMM Do, YYYY')}
            if post.categories && post.categories.length
                | in
                each cat, i in post.categories
                    a(href='/category/' + cat.key)= cat.name
        if post.image.exists
            img(src=post._.image.fit(160,160)).img.pull-right
        p!= post.content.brief

下面是mixin通常的样子：

mixin post(post)
.post(data-ks-editable=editable(user, { list: 'Post', id: post.id }))
    h2.entry-title=post.title
    p.lead.text-muted.entry-utility Posted
        if post.publishedDate
            | #{post._.publishedDate.format('MMMM Do, YYYY')}
        if post.categories && post.categories.length
            | in
            each cat, i in post.categories
                a(href='/category/' + cat.key)= cat.name
    if post.image.exists
        img(src=post._.image.fit(160,160)).img.pull-right
    p!= post.content.brief

我使用的是phpstorm，间距仅设置为制表符。

你的mixin主体（mixin post（post）下面的行）应该缩进一级。尝试过了，没有运气。谢谢你的回复。
