Node.js ReferenceError:未定义路径：Express

页面已呈现，但当我按下任何链接时，它会出错

ReferenceError: path is not defined

以下是server.js中的代码：

app.use(express.static('../build'));
app.get('*', (req, res)=> {
  const index = path.join(__dirname, '/', '../build', 'index.html' );
  res.sendFile(index);
});

提前感谢。

在文件的开头，只需添加

const path = require('path');

---

您需要路径模块吗

const path = require('path')

---

您是否在文件中添加了此要求路径

const path = require('path')

---

试试这个，它会起作用的

你能展示一下你的项目结构吗？例如，你可以创建一个使用。不知道我怎么会错过这个…这解决了问题！谢谢
