我也報同樣的錯，和視頻里代碼一模一樣，不知道怎么搞了?

new webpack.DefinPlugin? => new webpack.DefinePlugin 少寫個E

你是不是 只注意了 plugins里的配置，那你在頁首 引入了 webpack 了嗎？ 需要提供代碼，才能知道你具體的問題。

我也是同樣的問題 webpack 也引入了 和老師的代碼一樣

根據(jù)你的報錯來看，是webpack相關(guān)設(shè)置出了問題，可能是代碼寫錯了。
webpack.config.js里面-plugins里面需要寫以下：
new?webpack.DefinePlugin({
????????????'process.env':?{
????????????????NODE_ENV:?isDev???'"development"'?:?'"production"'
????????????}
????????}),
同時最上面需要引入webpack?
const?webpack?=?require('webpack')
