Node.js 玉，混合，延伸

鉴于以下情况

/layouts
   main.jade
/partials
   some.jade
index.jade

在main.jade中输入代码

html
    head
        title Layout page
    body
        block content

mixin list( title )
    h1 title
    ul
        li foo
        li bar
        li baz

extend ./layouts/main
extend ./partials/some
block content
    h1 Hello world
    +list( 'Ciao mondo' )

在some.jade中编码

html
    head
        title Layout page
    body
        block content

mixin list( title )
    h1 title
    ul
        li foo
        li bar
        li baz

extend ./layouts/main
extend ./partials/some
block content
    h1 Hello world
    +list( 'Ciao mondo' )

索引中的代码。jade

html
    head
        title Layout page
    body
        block content

mixin list( title )
    h1 title
    ul
        li foo
        li bar
        li baz

extend ./layouts/main
extend ./partials/some
block content
    h1 Hello world
    +list( 'Ciao mondo' )

我想知道是否有类似的方法，但运行时不会出现问题

尝试更换

extend ./layouts/main
extend ./partials/some
block content
    h1 Hello world
    +list( 'Ciao mondo' )
