脚本nodejs的ReferenceError

Question

我收到以下错误：

"Uncaught ReferenceError: Invalid left-hand side in assignment"

从这段代码：

const cheerioReq = require("cheerio-req");

//noinspection JSAnnotator
cheerioReq("https://my.alpinegqs.com/", (err, $) = {
  console:log($(".header h1").text()),

});

Answer 1

你错过了一支箭。试试这个：

const cheerioReq = require("cheerio-req");

//noinspection JSAnnotator
cheerioReq("https://my.alpinegqs.com/", (err, $) => {
  console.log($(".header h1").text()),

});

Answer 2

const cheerioReq = require("cheerio-req");

//noinspection JSAnnotator
cheerioReq("https://my.alpinegqs.com/", (err, $) => {
  console:log($(".header h1").text()),

});

那应该是箭头功能吗？在(err, $) =之后，您需要一个＆gt;
