在试图创建并使用与仅具有前端ReactJS / NextJS应用程序相关的ENV密码时，我在安装webpack时破坏了我的应用程序。

https://github.com/zeit/next.js/issues/805
在我使用npm install webpack之后，我意识到我不应该自己安装webpack，因为这已经由NextJS处理了。
所以我删除了我的node_modules文件夹，从我的package.json中删除了webpack，但现在当我尝试运行我的应用程序：npm run dev时，我得到以下错误：
moonholdings.io [actionsReducers●] % npm run dev
> moon.holdings@2.0.0 dev /Users/leongaban/projects/Futuratum/moonholdings.io
> next -p 7777

你有什么想法，为什么会发生这种情况？
我的 next.config.js 文件
const { PHASE_PRODUCTION_SERVER } =
process.env.NODE_ENV === 'development'
? {}
: !process.env.NOW_REGION
? require('next/constants')
: require('next-server/constants');
module.exports = (phase, { defaultConfig }) => {
if (phase === PHASE_PRODUCTION_SERVER) {
// Config used to run in production.
return {};
}
// ✅ Put the require call here.
const withTypescript = require('@zeit/next-typescript');
const withCSS = require('@zeit/next-sass');
return withTypescript(withCSS());
};
