Node.js Express 将模板引擎jade改成ejs

Question

我正在尝试使用以下更改来更改 Node.js Express 模板引擎。

app.js

app.set('view engine', 'jade'); 到 app.set('view engine', 'ejs');

Package.json

"jade": "~1.11.0", 至"ejs": "^1.0.0",

最后将View/* 扩展*.jade 更改为*.ejs。

但是在那之后我得到了这个错误：

在视图目录“/var/www/mynode/myapp/views”中查找视图“索引”失败

Error: Failed to lookup view "index" in views directory "/var/www/mynode/myapp/views"

更新

我当前的 app.js 文件：

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');

var routes = require('./routes/index');
var users = require('./routes/users');

var app = express();

// View engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');

// Uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));

app.use('/', routes);
app.use('/users', users);

// Catch 404 and forward to error handler
app.use(function(req, res, next) {
  var err = new Error('Not Found');
  err.status = 404;
  next(err);
});

// Error handlers

// Development error handler
// It will print stacktrace
if (app.get('env') === 'development') {
  app.use(function(err, req, res, next) {
    res.status(err.status || 500);
    res.render('error', {
      message: err.message,
      error: err
    });
  });
}

// Production error handler
// No stacktraces leaked to user
app.use(function(err, req, res, next) {
  res.status(err.status || 500);
  res.render('error', {
    message: err.message,
    error: {}
  });
});


module.exports = app;

Answer 1

在您的 app.js 文件中，替换

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

与

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

另外，您在 /views 中创建了 3 个索引文件？ 只需保留您需要的那个并重命名/替换其他的。并尝试重新运行它。

Answer 2

您有索引页面（根 URL）的路由，因此您需要在 /var/www/mynode/myapp/views 文件夹中的 index.ejs 文件。
