使用HBS时面临的问题

Question

我是一个完全的新手在后端，我正在学习速成和使用HBS作为模板引擎。每次在Express中使用hbs部分时，我都会遇到这种情况。

码

const express = require("express");
const app = express();
const hbs = require("hbs");
const path = require("path");
const port = process.env.PORT || 3000;

// public static path
const static_path = path.join(__dirname, "../public");
const templates_path = path.join(__dirname, "../templates/views");
const partials_path = path.join(__dirname, "../templates/partials");

app.set("view engine", "hbs");
app.set("views", templates_path);
hbs.registerPartial(partials_path);

app.use(express.static(static_path));

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

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

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

app.get("*", (req, res) => {
  res.status(404).render("404error");
});
app.listen(port, () => {
  console.log("listning on port " + port);
});

误差

throw new _exception2['default']('Attempting to register a partial called "' + name + '" as undefined');
        ^

}

增加这一点来增加诋毁，因为Stack溢出不允许我发布这个，因为我提升的代码比描述多，而且我不知道该问什么更多。

根据文档，它是- hbs.registerPartials(partials_path);而不是hbs.registerPartial(partials_path);
