我已经在app.js中使用此代码制作了在控制台中显示端口的信息，但在下面无法正常工作只是整个代码的一部分

const port = 8080;
app.listen(port, () => {
    console.log("hi its listening: ${port}!");
});

这是控制台的输出

hi its listening: ${port}!




const express=require('express');
const app=express();
const morgan=require('morgan');

const postRoutes=require("./routes/post");

app.use(morgan("dev"));

app.use('/',postRoutes);

 const port = 8080;//process.env.PORT || 8080;
 app.listen(port, () => {
 console.log("hi its listening: ${port}!");
 });

它应该显示：

hi its listening: 8080
