Server Error: Template render error: (unknown path)
  Error: template not found: ./_layout.html

Here is my code
app.js

const Koa           = require('koa');
const views         = require('koa-views');
// some code ...

App.use(views(__dirname + '/server/views', {
   map: { html: 'nunjucks' },
   cache: util.isDEV || util.isLOCAL ? false : 'memory'    
})); 

// other code ...

home.html

{% extends './_layout.html' %}

{% block head %}
    <title>Koa2 demo</title>
{% endblock %}

{% block body %}
    <h1>Home page</h1>
    <p>Hello World</p>   
{% endblock %}

version

"koa": "^2.2.0"
"koa-views": "^6.0.2"
"nunjucks": "^2.4.2"

home.html and _layout.html are in the same directory. and I'm not sure whose bug it is, koa-views? or nunjucks... need help. (neglect my poor english :) )

I use nunjucks template engine in Koa-views middleware

[laozhu]

I get the same problem with koa-views/nunjucks, is this solved?

[Tinyuen]

@laozhu 你是南京的？那我就不饶英文了（因为我英文也不好...）我用了koa-nunkucks-2 代替了，issue有阵子了，但是目前还没有答案....

const koaNunjucks   = require('koa-nunjucks-2');

App.use(koaNunjucks({
  ext: 'html',
  path: path.join(__dirname, '/server/views'),
  nunjucksConfig: {
    autoescape: true,
    noCache: util.isDEV || util.isLOCAL
  }
}));

[laozhu]

koa-nunjucks-2 确实可以解决问题，谢谢~
koa-views 还是没法使用 extends 和 include

[zhoulinxiang]

koa-nunjucks-2 怎么解决的。。我还是有问题啊

[vu-ji]

Error: template not found: _layout.njk

[fdintino]
