复制文件夹

    const fs = require("fs");

const copyDir = (sourcePath, targetPath) => {
    const flag1 = fs.existsSync(sourcePath)
    const flag2 = fs.existsSync(targetPath)
        //1.容错处理
    if (!flag1) {
        throw new Error("源目录不存在！！！" + sourcePath)
        return;
    }
    if (flag2) {
        throw new Error("目标目录存在！！！" + targetPath)
        return;
    }
    //2.创建目标文件
    fs.mkdirSync(targetPath);
    //3.读取源目录的子目录
    fs.readFileSync(sourcePath).forEach(item => {
            //拼接
            let midSourcePath = sourcePath + "/" + "item";
            let midTargetPath = targetPath + "/" + "item";
            //读取信息
            if (fs.statSync(midSourcePath).isFile()) {
                //是文件
                fs.copyFileSync(midSourcePath, midTargetPath)
            } else {
                //是文件夹（递归）
                copyDir(midSourcePath, midTargetPath)
            }
        })
        //copyDir("元目录","新目录")
