this.render is not a function

I’m using koa@2 and getting _this.render is not a function

this.render('index')

Doing ctx.render does work but I need to specify ‘index.pug’ and not just ‘index’. Also, not if it is related but string interpolation no longer works.

p.text-xs-center $ #{product.price}

Just outputs #{product.price} after it’s converted to html.

package.json
{
  "koa": "^2.0.0",
  "koa-pug": "^3.0.0-0"
}

koa-pug is not fully support koa@2 yet, though it can work.

1. koa@2 uses ctx instead of this for context of one request, please use ctx.render instead: https://github.com/koajs/koa/tree/v2.x#old-signature-middleware-v1x---deprecated .
2. About .pug extname and string interpolation, can you post your codes? I can’t reproduce these issues.

It is a bug of Pug, and fixed in alpha7: https://github.com/pugjs/pug/commit/2d79b88c9b4e37f1593c6d2ec7c79104df1b7c68 .

There’re two solutions:

• If you’re using npm ^3.7, you can run npm i pug@2.0.0-alpha7
• Reinstall koa-pug, npm will install latest Pug for you.
