webpack2項目中引入@vue/composition-api報錯Cannot find module

在webpack.base.conf.js中的vue配置中加入

transpileOnly: true,

如下為完整配置：

{
        test: /\.vue$/,
        loader: 'vue-loader',
        options: {
          loaders: {
            ts:  [
              {
                loader: 'ts-loader',
                options: {
                  transpileOnly: true,
                  appendTsSuffixTo: [/\.vue$/]
                }
              }],
            scss: [
              'vue-style-loader!css-loader!sass-loader',
              // 全局sass變量
              {
                loader: 'sass-resources-loader',
                options: {
                  // 需更改為項目中實際scss文件路徑
                  resources: path.resolve(__dirname, '../src-mobile/styles/global.scss'),
                },
              },
            ], // <style lang="scss">
            sass: 'vue-style-loader!css-loader!sass-loader' // <style lang="sass">
          },
          options: {
            esModule: true
          }
        }
      },
