我有两个关于 react.js 的问题：

1. 我正在使用npx create-react-app xxx初始化我的项目，每次我在做的时候遇到错误yarn start

Error: Cannot find module 'lodash.template'

Require stack:

- C:\Desktop\react\myapp\node_modules\workbox-build\build\lib\populate-sw-template.js

- C:\Desktop\react\myapp\node_modules\workbox-webpack-plugin\build\generate-sw.js

}

我正在尝试使用以下方法计算从现在起 100 天的时间：

import java.util.Date;
public class Main
{
    public static void main(String[] args) {
        System.out.println("Hello World");
        System.out.println(new Date(System.currentTimeMillis() + 8640000 * 1000));
    }
}

它给了我Jan 04 08:57:25 UTC 2021不正确的回报。我该如何补救？
