Question

我正在尝试使用Nunjucks作为Express的模板引擎。我这样做了：

var express = require('express');
var nunjucks = require('nunjucks');
var path = require('path');
var bodyParser = require('body-parser');
var load = require('express-load');
var fs = require("fs");

var app = express();
app.set('views', path.join(__dirname, 'views'));

var env = nunjucks.configure(app.get('views'), {
    autoescape: true,
    express:    app 
});

app.set('view engine', 'html');

但是上面的代码给出了这个错误：

Template render error: compileExtends: cannot extend multiple times
   at Error.exports.TemplateError (C:\my\nodejs\projects\\node_modules\nunjucks\src\lib.js:49:19)
   at Object.extend.fail (C:\my\nodejs\projects\\node_modules\nunjucks\src\compiler.js:49:15)

   at Obj.extend.compile (C:\my\nodejs\projects\\node_modules\nunjucks\src\environment.js:403:18)

请告诉我如何解决这个问题？

我这样用过：

nunjucks.configure('views', {
    express: app,
    autoescape: true
});
app.set('view engine', 'html');

如果要将模板文件夹放在$ {pwd} / teampltes

上

像下面一样。

//import
const path = require('path')

const express = require('express')
const nunjucks = require('nunjucks')


//init
const app = express()

nunjucks.configure(path.join(__dirname, 'templates'), {
    autoescape: true,
    express: app
})

这就像使用 express js 的基本配置，您可以这样做：

const express = require('express');
const nunjucks = require('nunjucks');
const app = express();

nunjucks.configure('views',{
    autoescape:true,
    express:app
});

app.set('views','./views'); // <--Path to your views folder

app.get('/',(request,response)=>{
    response.render('some-view.html');
});

我只是使用默认方式设置 nunjucks：

const express = require('express');
const nunjucks = require('nunjucks');

const app = express();
app.engine('html', nunjucks.render);
app.set('view engine','html');
app.set('views', globals.viewsDirectory);

"express": "4.16.4", "nunjucks": "^3.2.3",

使用Nunjucks和Express 4
