Question

当我在heroku中部署我的node.js网页时，我没有在日志中收到任何错误，但是当我转到生成的 url 时，我收到了这个错误：

Ingore mongoose 错误，我已经解决了这个问题，但不断收到这个错误 Error: Failed to lookup view "home" in views directory "app/views"我的 node-express 视图和公共路径是：

app.use(express.static(path.join(__dirname, '/public')));
app.set('views', path.join(__dirname, '/views'));
//my port is on
const port = process.env.PORT || 3000

我试过这个：

app.use(express.static(path.join(__dirname, '../public')));
app.set('views', path.join(__dirname, '../views'));

正如我在这里读到的那样，它有效，但它对我不起作用，我收到了同样的错误。
