Question

我在teamTreeHouse上做这个教程 https://teamtreehouse.com/library/express-basics/using-templates-with-express/using-jade-in-your-express-app

我收到此错误：

TypeError: Cannot read property '_locals' of undefined
   at EventEmitter.render (c:\Users\bcarr\Web Projects\LTQ\node_modules\express\lib\application.js:548:11)
   at c:\Users\bcarr\Web Projects\LTQ\app.js:12:9

   at expressInit (c:\Users\bcarr\Web Projects\LTQ\node_modules\express\lib\middleware\init.js:33:5)

现在从我从这个域读取的内容来看，我没有名为_locals的文件夹。

./catalina run

我正在使用这些代码行启动它。我正在使用

app.set('view engine', 'jade');
app.set('views', './templates');

但我的app.js与我的模板文件夹位于同一文件夹中＃34; LTQ＆＃34;

为什么我会收到这个错误？这是什么意思？

Answer 1

你可以省略点，看看会发生什么。我是说这个

app.set('views', __dirname + '/templates');

什么是＆＃39; TypeError：无法读取属性＆＃39; _locals＆＃39;未定义的＆＃39;意思？
