express js 路由缓存清除（heroku）

Question

我正在使用 express js 并添加了新的 .pug 文件并在 routes/index.js 中给出了链接

但是当我尝试在浏览器 url 中访问时，它被重定向到（404 页面未找到）

我能知道如何清除路由缓存吗？在我以前的 nodejs 应用程序中，它有 pm2，所以我重新启动了它。但是这里没有pm2，我不知道该怎么办？。任何帮助将不胜感激。

注意：我已经尝试过这个link 但不起作用。

路由/index.js

// set up dependencies
var express = require('express');
var router = express.Router();
//
//
// Home Page
router.get('/', function(req, res, next) {
  res.render('home', {
    meta : {
      title: 'Home'
    }
  })
});
//
//
// About Page
router.get('/about', function(req, res, next) {
  res.render('about', {
    meta : {
      title: 'About Us'
    }
  })
});
//
//
//Partners Page
router.get('/partners', function(req, res, next) {
  res.render('partners', {
    meta : {
      title: 'Partners'
    }
  })
});

//
//
// export the module
module.exports = router;

  err.status = 404;
  next(err);

  res.status(err.status || 404);
  // log the error for heroku logs
  console.log('error', err);
  res.render('error', {});
});

// serve the app on PORT variable
// if using Heroku, this will be automatically set
var server = app.listen(port, function(err) {
  if (err) {
    console.log('App listening error ', err);
  } else {
    console.log('App running at ', port)

});

最后朋友调试了代码，发现错误在partners.pug文件中。间距问题。所以我复制了另一个 pug 文件并重命名为 partners.pug 并链接到 routes/index.js 它然后工作。它可能对某人有所帮助。
