VueJs模块构建失败：错误：无法找到相对于目录的预设“@ vue / app”

Question

I'm using vue-tour in my app, the problem is that when i imported the library my app doesn't work anymore, this the error when i try the command npm run dev :

 error  in ./~/vue-tour/dist/vue-tour.umd.js

Module build failed: Error: Couldn't find preset "@vue/app" relative to directory "C:\\xampp\\htdocs\\avanttia\\node_modules\\vue-tour"

 @ ./resources/assets/js/wizard/main.js 49:15-34
 @ multi ./resources/assets/js/wizard/main.js

Importing the library like this:

import '@/bootstrap'

import VueDragDrop from 'vue-drag-drop'
import VueTour from 'vue-tour'

import Wizard from '@/wizard/containers/Wizard.vue'

require('/node_modules/vue-tour/dist/vue-tour.css')

const Vue = window.Vue

Vue.use(VueTour)
Vue.use(VueDragDrop)

const vm = new Vue({
  el: '#wizard-app',
  render: h => h(Wizard)
})

export default vm

Edit: This is mi .babelrc config file:

{
  "presets": [
    [ "env", {
      "targets": {
        "uglify": true,
        "node": "current"
      },
      "modules": false,
      "loose": true,
      "useBuiltIns": true,
      "debug": true,
    }]
  ],
  "plugins": [
    ["component", [{
      "libraryName": "element-ui",
      "styleLibraryName": "theme-chalk"
    }]],
    ["module-resolver", {
      "alias": {
        "@": "./resources/assets/js"
      }
    }],
    ["transform-es2015-template-literals", {
      "loose": true,
      "spec": true
    }]

  ],

}

and the .babelrc config file from the vue-tour library:

{
  "presets": [
    "@vue/app"
  ]
}

Why vue can't find @vue/app?, looks like there is a conflict in the alias property, but i have no idea how to change without breaking the project config.

update: if in the node_modules/vue-tour library i change the .babalrc file to this:

"presets": [
        "es2015"
      ]

it works as expected, but this is undesired as i have to change everywhere i have to deploy this project.

Answer 1

After days struggling with this issue, i finally found a solution for this:

In the webpack.mix.js the es2015 transpilation was done like this:

  {
        test: /\.js$/,
        exclude: /node_modules\/(?!(some-library)\/).*/,
        include: [/node_modules\/vue-tour/], // <---Added this line!
        use: {
          loader: 'babel-loader',
          options: {
            presets: ['env']
          }
        }
      }
