關(guān)于vue-hackernews-2.0運(yùn)行的問(wèn)題

想學(xué)習(xí)一下vue-hackernews-2.0這個(gè)例子，就從github上clone了一份。
運(yùn)行npm install后提示

npm notice created a lockfile as package-lock.json. You should commit this file.
npm WARN extract-text-webpack-plugin@2.1.2 requires a peer of webpack@^2.2.0 but none is installed. You must install peer dependencies yourself.
npm WARN sw-precache-webpack-plugin@0.10.1 requires a peer of webpack@^1 || ^2 || ^2.1.0-beta || ^2.2.0-beta but none is installed. You must install peer dependencies yourself.

我安裝著webpack3應(yīng)該沒(méi)什么影響。

然后我npm run dev提示正常

> vue-hackernews-2.0@ dev /Users/fuckc/Documents/vue-hackernews-2.0
> node server

server started at localhost:8080


 DONE  Compiled successfully in 2518ms                                            19:15:38



 DONE  Compiled successfully in 2818ms                                            19:15:38

webpack built 1345b8affebfcb6afefa in 2818ms

但是網(wǎng)頁(yè)卻沒(méi)有彈出來(lái)，
我又執(zhí)行了npm run build 和npm start依然沒(méi)有彈出網(wǎng)站，
請(qǐng)問(wèn)這是什么情況？
