Why dynamic component import in router throwing error?

ERROR in ./src/routes.js
Module build failed (from ./node_modules/babel-loader/lib/index.js):
SyntaxError: Unexpected token (24:33)

You can use const vueComponent = await import('./assets/vue/pages/about.vue');

it seems you haven't installed babel-preset-env package. Revert to const vueComponent = () => import('./assets/vue/pages/about.vue'); and run npm install --save-dev babel-preset-env to install package and create file .babelrc with following content.

 {
  "presets": ["env"]
} 

i think this will fix the babel compiling error.

[anilwarbhe]

babel-preset-env is already installed as I am using THIS template. It's there in json file. But as you mentioned I have created a .babelrc file and copied the content you had asked but still receiving the same error.

I fix it:

\config\webpack.common.js loader: 'babel-loader' add plugin: 'syntax-dynamic-import'

then: npm install [email protected] -D

Unexpected token webpack import() error will be ok.
