如何在外部主机上访问Vue.js应用程序

Question

我开始使用Django和Vue.js在digital ocean上做一个小项目。我已经安装了所有东西，但是当我运行 npm run serve，我在浏览器中只看到一个黑色页面，因为我安装了Django网页加载程序 这是我的包。json

    {
  "name": "frontend",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint"
  },
  "dependencies": {
    "core-js": "^3.6.5",
    "vue": "^3.0.0"
  },
  "devDependencies": {
    "@vue/cli-plugin-babel": "~4.5.0",
    "@vue/cli-plugin-eslint": "~4.5.0",
    "@vue/cli-service": "~4.5.0",
    "@vue/compiler-sfc": "^3.0.0",
    "babel-eslint": "^10.1.0",
    "eslint": "^6.7.2",
    "eslint-plugin-vue": "^7.0.0-0",
    "webpack-bundle-tracker": "^1.0.0-alpha.1"
  },
  "eslintConfig": {
    "root": true,
    "env": {
      "node": true
    },
    "extends": [
      "plugin:vue/vue3-essential",
      "eslint:recommended"
    ],
    "parserOptions": {
      "parser": "babel-eslint"
    },
    "rules": {}
  },
  "browserslist": [
    "> 1%",
    "last 2 versions",
    "not dead"
  ]
}

这是我的vue.config.js

const BundleTracker = require('webpack-bundle-tracker');


module.exports = {
    publicPath: "http://0.0.0.0:8080",
    outputDir: "./dist/",

    chainWebpack: config => {
        config.optimization.splitChunks(false)

        config.plugin('BundleTracker').use(BundleTracker, [
            {
                filename: './webpack-stats.json'
            }
        ])

        config.resolve.alias.set('__STATIC__', 'static')

        config.devServer
            .public('http://0.0.0.0:8080')
            .host('0.0.0.0')
            .port(8080)
            .hotOnly(true)
            .watchOptions({poll: 1000})
            .https(false)
            .headers({'Access-Control-Allow-Origin': ['\*']})
    }
};
