基于 docker 的 Vue 项目中的热重载-PHP中文网问答

您好，我的 vue 项目遇到问题。 我在 docker 中有前端后端和后端数据库。 这是 vue.config.js 配置： <pre class="brush:php;toolbar:false;">module.exports = defineConfig({ configureWebpack: { entry: "./src/main.js", devServer: { hot: true, }, watch: true, watchOptions: { ignored: /node_modules/, poll: 500, }, }, transpileDependencies: true })</pre> 容器在创建过程中会自行安装 npm 和 package.json 中给出的包： <pre class="brush:php;toolbar:false;">{ "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": { "@morioh/v-smooth-scrollbar": "^1.0.3", "@vuepic/vue-datepicker": "^4.2.0", "@vueuse/core": "^9.13.0", "ajax": "^0.0.4", "axios": "^1.3.3", "core-js": "^3.8.3", "mitt": "^3.0.0", "register-service-worker": "^1.7.2", "smoothscroll-polyfill": "^0.4.4", "vue": "^3.2.13", "vue-axios": "^3.5.2", "vue-class-component": "^8.0.0-0", "vue-router": "^4.0.3", "vuex": "^4.0.0" }, "devDependencies": { "@typescript-eslint/eslint-plugin": "^5.4.0", "@typescript-eslint/parser": "^5.4.0", "@vue-leaflet/vue-leaflet": "^0.8.4", "@vue/cli-plugin-babel": "~5.0.0", "@vue/cli-plugin-eslint": "~5.0.0", "@vue/cli-plugin-pwa": "~5.0.0", "@vue/cli-plugin-router": "~5.0.0", "@vue/cli-plugin-typescript": "~5.0.0", "@vue/cli-plugin-vuex": "~5.0.0", "@vue/cli-service": "~5.0.0", "@vue/eslint-config-typescript": "^9.1.0", "eslint": "^7.32.0", "eslint-plugin-vue": "^8.0.3", "leaflet": "^1.9.3", "sass": "^1.32.7", "sass-loader": "^12.0.0", "typescript": "~4.5.5" }, "eslintConfig": { "root": true, "env": { "node": true }, "extends": [ "plugin:vue/vue3-essential", "eslint:recommended", "@vue/typescript/recommended" ], "parserOptions": { "ecmaVersion": 2020 }, "rules": {} }, "browserslist": [ "> 1%", "last 2 versions", "not dead", "not ie 11" ] }</pre> 我发布了所有内容，这样就不会造成混乱:) 直到昨天，一切都对我来说一切正常，但今天重新启动容器后，页面的热重新加载选项停止工作。 当容器启动时，我得到以下输出： <pre class="brush:php;toolbar:false;">frontend | App running at: frontend | - Local: http://localhost:8080/ frontend | - Network: http://172.26.0.4:8080/ frontend | No issues found.</pre> 当我使用 http://localhost:8080 在浏览器中启动页面时，页面会加载，但保存更改时的实时重新加载选项已停止工作。 在控制台中我可以看到浏览器尝试下载更新但没有得到响应 <pre class="brush:php;toolbar:false;">WebSocket connection to 'ws://172.26.0.4:8080/ws' failed: WebSocketClient @ WebSocketClient.js?5586:16 initSocket @ socket.js?d6e0:24 eval @ socket.js?d6e0:48</pre> 我尝试从头开始放置容器。 我使用了旧版本的 kyod，但在撰写后此选项仍然不起作用 当我手动刷新页面时，内容会正确更改。 你知道问题出在哪里吗 此外，在其他计算机上它也可以正常工作。 他们编译整个项目的时间比我晚，所以如果它依赖于某些节点模块，它也将无法工作。不管怎样，我已经尝试自己从头开始创建容器两天了，所以没有任何node_模块是过时的。问题不在配置中，因为一天前它还可以工作。或者我的电脑上是否有某些内容可能会阻止 ws://172.26.0.4:8080/ws 的流量 此外，它在其他浏览器上看起来是相同的。 我目前正在安装一个虚拟机来检查它仍然像这样，但很想听听关于我还可以检查什么的建议。 感谢您的提前互动并期待您！
