导入不带.vue扩展名的* .vue文件时出现以下错误？

Question

导入不带.vue扩展名的vue文件时出现以下错误。

./~/babel-loader/lib!./~/vue-loader/lib/selector.js?type=script&index=0!./src/App.vue中找不到错误：错误：无法解析' ./components/Navbar'

我的Web back配置如下

module: {
    rules: [
      {
        test: /\.vue$/,
        loader: 'vue-loader',
        options: {
          loaders: {
            // Since sass-loader (weirdly) has SCSS as its default parse mode, we map
            // the "scss" and "sass" values for the lang attribute to the right configs here.
            // other preprocessors should work out of the box, no loader config like this necessary.
            'scss': 'vue-style-loader!css-loader!sass-loader',
            'sass': 'vue-style-loader!css-loader!sass-loader?indentedSyntax'
          }
          // other vue-loader options go here
        }
      },
      {
        test: /\.js$/,
        loader: 'babel-loader',
        exclude: /node_modules/
      },
      {
        test: /\.(png|jpg|gif|svg)$/,
        loader: 'file-loader',
        options: {
          name: '[name].[ext]?[hash]'
        }
      }
    ]
  },
  resolve: {

    alias: {
      'vue$': 'vue/dist/vue.esm.js'
    }
  },

Answer 1

问题出在您的Webpack配置中。要使Webpack自动解析.vue扩展名，请使用resolve.extensions选项，并包括默认值。

resolve: {
    extensions: ['*', '.js', '.vue', '.json']
}

Answer 2

问题出在 Webpack 配置上。

.vue通过在 Webpack 中包含扩展数组，使 Webpack 自动解析扩展resolve

 resolve: {
    extensions: ['.vue'],
   },
