Question

这是我的代码

   //Require modules
var http = require("http");
var url = require("url");
var path = require("path");
var fs = require("fs");

var mimeTypes = {
  html: "text/html",
  jpeg: "image/jpeg",
  png: "image/png",
  jpg: "image/jpg",
  js: "text/javascript",
  css: "text/css",
};

http
  .createServer(function (req, res) {
    var uri = url.parse(req.url).pathname;
    var fileName = path.join(process.cwd, unescape(uri));
    console.log("Loading " + uri);
    var stats;

    try {
      stats = fs.lstatSync(fileName);
    } catch (error) {
      res.writeHead(404, { "Content-type": "text/plain" });
      res.write("404 not Found");
      res.end();
      return;
    }
    if (stats.isFile()) {
      var mimeType = mimeTypes[path.extname(fileName).split(".").reverse()[0]];
      res.writeHead(200, { "Content-type": mimeType });

      var fileStream = fs.createReadStream(fileName);
      fileStream.pipe(res);
    } else if (stats.isDirectory) {
      res.writeHead(302, { location: "index.html" });
      res.end();
    } else {
      res.writeHead(500, { "Content-Type": "text/plain" });
      res.write("500 Internal Error");
      res.end();
    }
  })
  .listen(3000);

这是在终端中查看的错误：

我是NodeJS的新手，我从youtube教程中学习。我也创建了index.html页面。我试图在以下位置运行index.html页面：“ http://127.0.0.1:3000/index.html”。我确实做了他们所做的。我重新检查了任何错误。请帮助我...预先感谢

将process.cwd更改为process.cwd()。您正在使用旧版本的node.js中的语法。这是当前的API reference

TypeError [ERR_INVALID_ARG_TYPE]：“路径”参数必须为字符串类型。接收函数wrapedCwd
