enter image description here

我的源码也很简单：

const express = require("express");
const app = express();

app.set("views", "./views");
app.set("view engine", "ejs ");

app.get("/", (req, res) => {
  res.render("home/index");
});

app.get("/login", (req, res) => {
  res.render("home/login");
});

app.listen(3000, function () {
  console.log("working");
});

Answer 1

去掉ejs后面的空格

从：

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

到：

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