node.js - 使用 Express for NodeJS 时出错 : 'engine' of object # is not a function

Question

我是 nodejs 的新手，想知道是否有人知道如何调试这个错误:

TypeError: Property 'engine' of object #<View> is not a function

在 ubuntu 机器上安装了 node/npm 之后，我刚刚安装了一个 express 实例。有任何想法吗？这是我的堆栈跟踪:

500 TypeError: Property 'engine' of object #<View> is not a function
at View.render (/var/www/node_modules/express/lib/view.js:75:8)
at Function.app.render (/var/www/node_modules/express/lib/application.js:504:10)
at ServerResponse.res.render (/var/www/node_modules/express/lib/response.js:676:7)
at exports.index (/var/www/routes/index.js:7:7)

at pass (/var/www/node_modules/express/lib/router/index.js:146:5)

at Object.router (/var/www/node_modules/express/lib/router/index.js:33:10)
at next (/var/www/node_modules/express/node_modules/connect/lib/proto.js:190:15)

这是 routes/index.js 7:7:

res.render('index', { title: 'Express' });

我明白了。问题是我没有正确安装依赖项。在我运行此命令后它起作用了:

cd . && sudo npm install

我之前为使应用程序运行而发出的命令引用了本教程的第一部分:
