Question

升级项目JS软件包后，使用Webpack构建捆绑包时出现错误。它似乎在构建.vue文件时出现，并且可以出现在任何.vue文件构建中。我的package.json中没有“ babylon”，并且我有一个更新的@ babel / core版本（7.2.2）。

这是错误：

{ parser: "babylon" } is deprecated; we now treat it as { parser: "babel" }

它似乎仅在构建.vue文件时出现。

这是我的配置：

.babelrc

{
  "presets": ["@babel/preset-env"],
  "plugins": ["@babel/plugin-transform-regenerator"]
}

Webpack配置：

module: {
rules: [
  {
    enforce: 'pre',
    test: /\.(js|vue)$/,
    loader: 'eslint-loader',
    exclude: /node_modules/
  },
  {
    test: /\.vue$/,
    loader: 'vue-loader',
    options: {
      loaders: {
        scss: 'vue-style-loader!css-loader!sass-loader',
        sass: 'vue-style-loader!css-loader!sass-loader?indentedSyntax'
      }
    }
  },
  {
    test: /\.js$/,
    exclude: /node_modules/,
    use: [ 'babel-loader' ]
  },
  {
    test: /\.sass$/,
    exclude: /node_modules/,
    use: ExtractTextPlugin.extract({
      fallback: 'style-loader',
      use: [
        {
          loader: 'css-loader',
          options: {
            sourceMap: true
          }
        },
        {
          loader: 'postcss-loader',
          options: {
            sourceMap: true
          }
        },
        {
          loader: 'sass-loader',
          options: {
            sourceMap: true
          }
        }
      ]
    })
  }
]

}

.eslintrc.js

  extends: [
'eslint:recommended',
'plugin:vue/recommended',
'plugin:import/errors',
'plugin:import/warnings'
],
 settings: {
'import/resolver': {
  'node': {
    'extensions': [
      '.js',
      '.vue'
    ]
  }
 }
 },
  parserOptions: {
  parser: 'babel-eslint',
  ecmaVersion: 2018

Answer 1

问题来自vue-loader 13.x.x和14.x.x

版本15.x.x似乎不错，但是我不能在不破坏所有内容的情况下将项目更新到15.x.x。（我想您会遇到同样的问题）

我将在项目仓库中记录一个问题，很幸运他们会发布修复程序。

编辑：

目前，您可以使用我创建的14.2.2的派生版本来消除此消息。不知道它是否与您的版本兼容。

尝试替换：

"vue-loader": "13.7.2",

使用

"vue-loader": "https://github.com/graux/vue-loader#a0d6b77",

Answer 3

或者仅在您的vue-loader": "^11.0.0中添加package.json即可完成

解析器“ babylon”已弃用错误-Webpack构建
