npm install iconv-lite --save

const iconv = require('iconv-lite');

// 假设你有一个GB2312编码的Buffer或Uint8Array类型的变量gb2312Data
let gb2312Data = ...; // 这里应该是你的GB2312编码数据


// 使用iconv-lite将GB2312编码的数据转换为汉字
let utf8Data = iconv.decode(gb2312Data, 'gb2312');


console.log(utf8Data); // 输出转换后的汉字字符串

引入之后编译就报错
