Vuejs 3 webpack:vue-template-compiler 的问题 [英] Vuejs 3 webpack : Problem with vue-template-compiler

问题描述

我正在尝试将 vuejs 3 集成到使用 webpack 的现有项目中.我读过 vue-loader，所以我正在尝试使用它.

在官方文档中我有这个:

vue 每次发布新版本时，都会同时发布相应版本的 vue-template-compiler.编译器的版本必须与基础 vue 包同步，以便 vue-loader 生成与运行时兼容的代码.这意味着每次升级项目中的 vue 时，都应该升级 vue-template-compiler 以匹配它.

因此，当我尝试编译时出现此错误:

Vue 包版本不匹配:- vue@3.0.2 (/home/alejo/playground/parquesFrontend/node_modules/vue/index.js)- vue-template-compiler@2.6.12 (/home/alejo/playground/parquesFrontend/node_modules/vue-template-compiler/package.json)这可能会导致事情无法正常工作.确保对两者使用相同的版本.如果您使用的是 vue-loader@>=10.0，只需更新 vue-template-compiler.如果您使用的是 vue-loader@<10.0 或 vueify，重新安装 vue-loader/vueify 应该会将 vue-template-compiler 提升到最新版本.

但是当我尝试安装 vue-template-compiler@3.0.2 时出现此错误:

❯ npm install vue-template-compiler@3.0.2错误！代码 ETARGETnpm 错误！notarget 找不到与 vue-template-compiler@3.0.2 匹配的版本.npm 错误！notarget 在大多数情况下，您或您的依赖项之一正在请求npm 错误！notarget 不存在的包版本.npm 错误！可以在以下位置找到此运行的完整日志:错误！/home/alejo/.npm/_logs/2020-11-17T02_52_46_458Z-debug.log

我该如何解决这个问题?

解决方案

要使 vue 3 在不使用 vite 或 vue cli 的情况下与 webpack 一起正常工作，请执行以下步骤:

1. 初始化 package.json 像:

<代码>{私人":真的，名称":vue-3"，描述":空，}

2. 安装最新版本的 vue :

npm i --save vue@next vue-loader@next

3. 还安装包括替换 vue-template-compiler
的 @vue/compiler-sfc 的开发依赖项

npm i -D @vue/compiler-sfc css-loader file-loader mini-css-extract-pluginurl-loader webpack webpack-cli webpack-dev-server

• @vue/compiler-sfc
• css-loader
• 文件加载器
• mini-css-extract-plugin
• 网址加载器
• vue-loader
• webpack
• webpack-cli
• webpack-dev-server

4. 使用以下内容创建或编辑您的 webpack.config.js :

const path = require("path");const { VueLoaderPlugin } = require(vue-loader");const MiniCssExtractPlugin = require(mini-css-extract-plugin");module.exports = (env = {}) =>({模式: env.prod ?生产":发展"，开发工具:env.prod ?源地图":廉价模块评估源地图"，入口: [require.resolve(`webpack-dev-server/client`),path.resolve(__dirname, "./src/main.js")].过滤器(布尔)，输出: {路径:path.resolve(__dirname, "./dist"),公共路径:/dist/"；},解决: {别名:{//这在技术上不是必需的，因为打包器的默认 `vue` 条目//是一个简单的 `export * from '@vue/runtime-dom`.然而有了这个//额外的重新导出以某种方式导致 webpack 总是使模块无效//在第一次 HMR 更新并导致页面重新加载.vue: "@vue/runtime-dom";}},模块: {规则: [{测试:/\.vue$/,使用:vue-loader"},{测试:/\.png$/,用: {加载器:网址加载器"，选项:{限制:8192}}},{测试:/\.css$/,用: [{加载器:MiniCssExtractPlugin.loader，选项:{ hmr: !env.prod }},css加载器"]}]},插件: [新的 VueLoaderPlugin(),新的 MiniCssExtractPlugin({文件名:[名称].css"})],开发服务器:{内联:真实，热:真的，统计数据:最小"，contentBase: __dirname,叠加:真实，注入客户端:假，disableHostCheck: 真}});

5. 添加 dev 脚本以运行您的应用:

<代码>{私人":真的，脚本":{开发":webpack-dev-server"},依赖关系":{vue":^3.0.2"},名称":vue-3"，描述":空，开发依赖":{...}}

6. 用以下内容填充index.html:

最后运行npm run dev访问http://localhost:8080/

为了准备好使用的项目，尝试克隆这个

I am trying to integrate vuejs 3 to an existing project which uses webpack. I read about vue-loader, so I am trying to use it.

In the official documentation I have this:

Every time a new version of vue is released, a corresponding version of vue-template-compiler is released together. The compiler's version must be in sync with the base vue package so that vue-loader produces code that is compatible with the runtime. This means every time you upgrade vue in your project, you should upgrade vue-template-compiler to match it as well.

So, when I try to compile I get this error:

Vue packages version mismatch:

- vue@3.0.2 (/home/alejo/playground/parquesFrontend/node_modules/vue/index.js)
- vue-template-compiler@2.6.12 (/home/alejo/playground/parquesFrontend/node_modules/vue-template-compiler/package.json)

This may cause things to work incorrectly. Make sure to use the same version for both.
If you are using vue-loader@>=10.0, simply update vue-template-compiler.
If you are using vue-loader@<10.0 or vueify, re-installing vue-loader/vueify should bump vue-template-compiler to the latest.

But when I try to install vue-template-compiler@3.0.2 I get this error:

❯ npm install vue-template-compiler@3.0.2
npm ERR! code ETARGET
npm ERR! notarget No matching version found for vue-template-compiler@3.0.2.
npm ERR! notarget In most cases you or one of your dependencies are requesting
npm ERR! notarget a package version that doesn't exist.

npm ERR! A complete log of this run can be found in:
npm ERR!     /home/alejo/.npm/_logs/2020-11-17T02_52_46_458Z-debug.log

How can I solve this problem?

解决方案

To make vue 3 work fine with webpack without using vite or vue cli follow these steps :

1. init the package.json like :

{
    "private": true,
    "name": "vue-3",
    "description": null,
   
}

2. install the last version of vue :

npm i --save vue@next vue-loader@next

3. install also the dev dependencies that includes @vue/compiler-sfc which replaces vue-template-compiler

npm i -D @vue/compiler-sfc css-loader file-loader mini-css-extract-plugin
 url-loader webpack webpack-cli webpack-dev-server

• @vue/compiler-sfc
• css-loader
• file-loader
• mini-css-extract-plugin
• url-loader
• vue-loader
• webpack
• webpack-cli
• webpack-dev-server

4. create or edit your webpack.config.js with following content :

const path = require("path");
const { VueLoaderPlugin } = require("vue-loader");
const MiniCssExtractPlugin = require("mini-css-extract-plugin");

module.exports = (env = {}) => ({
  mode: env.prod ? "production" : "development",
  devtool: env.prod ? "source-map" : "cheap-module-eval-source-map",
  entry: [
    require.resolve(`webpack-dev-server/client`),
    path.resolve(__dirname, "./src/main.js")
  ].filter(Boolean),
  output: {
    path: path.resolve(__dirname, "./dist"),
    publicPath: "/dist/"
  },
  resolve: {
    alias: {
      // this isn't technically needed, since the default `vue` entry for bundlers
      // is a simple `export * from '@vue/runtime-dom`. However having this
      // extra re-export somehow causes webpack to always invalidate the module
      // on the first HMR update and causes the page to reload.
      vue: "@vue/runtime-dom"
    }
  },
  module: {
    rules: [
      {
        test: /\.vue$/,
        use: "vue-loader"
      },
      {
        test: /\.png$/,
        use: {
          loader: "url-loader",
          options: { limit: 8192 }
        }
      },
      {
        test: /\.css$/,
        use: [
          {
            loader: MiniCssExtractPlugin.loader,
            options: { hmr: !env.prod }
          },
          "css-loader"
        ]
      }
    ]
  },
  plugins: [
    new VueLoaderPlugin(),
    new MiniCssExtractPlugin({
      filename: "[name].css"
    })
  ],
  devServer: {
    inline: true,
    hot: true,
    stats: "minimal",
    contentBase: __dirname,
    overlay: true,
    injectClient: false,
    disableHostCheck: true
  }
});

5. Add dev script to run your app :

{
    "private": true,
    "scripts": {
        "dev": "webpack-dev-server"
    },
    "dependencies": {
        "vue": "^3.0.2"
    },
    "name": "vue-3",
    "description": null,
    "devDependencies": {
      ...
    }
}

6. Fill the index.html with following content :

<link rel="stylesheet" href="/dist/main.css" />
<div id="app"></div>
<script src="/dist/main.js"></script>

Finally run npm run dev the visit http://localhost:8080/

for a ready to use project try to clone this REPOSITORY which built by following the steps above.
