Node.js 如何使用显示错误的NodeEmailer发送hbs模板？

模板位于

views/email

目录下，文件名为

index.hbs

，布局文件名为

layout.hbs

，位于

views/email

目录下，零件标签位于

views/email/patartials

目录下

如果将布局扩展设置为布局。hbs显示ann错误

布局。未找到把手。如果像
layout.handlebar
那样设置，则不会显示错误。但总是会出现此错误
{“errno”：-2，“code”：“enoint”，“syscall”：“open”，“path”：“/home/user/Documents/Master Project/views/email/index.hbs”}

为了发送邮件，我使用了
nodemailer
npm软件包，还安装了
nodemailer express手柄
，用于编译hanldebars模板

这是我的代码

const nodemailer = require("nodemailer");
const hbs = require("nodemailer-express-handlebars");

var transporter = nodemailer.createTransport({
  service: "gmail",
  auth: {
    user: process.env.MAIL,
    pass: process.env.PASS,
  },
});
var options = {
  viewEngine: {
    extName: ".hbs" /* or '.handlebars' */,
    viewPath: __dirname + "/views/email/",
    layoutsDir: __dirname + "/view/email",
    defaultLayout: "layout",
    partialsDir: __dirname + "/views/email/partials/",
  },
  viewPath: "views/email/",
};

transporter.use(
  "compile",
  hbs({
    viewEngine: {
      extName: ".hbs",
      viewPath: "../views/email/",
      layoutsDir: "../views/email/",
      defaultLayout: "layout",
      partialsDir: "../views/email/partials/",
    },
    viewPath: "../views/email",
    extName: ".hbs",
  })
);

router.get("/mail", (req, res) => {
  let mailOptions = {
    from: process.env.FROMMAIL,
    to: "req.body.email",
    subject: "Testing",
    template: "index",
  };
  transporter.sendMail(mailOptions, (error, data) => {
    if (error) return res.send(error);
    res.send("Mail Send");
  });
});
