I use vue-cli-3.0 rc.8 to create the project:

vue create test2

except pwa, I select all options, and config as below

Vue CLI v3.0.0-rc.8
? Please pick a preset: Manually select features
? Check the features needed for your project: Babel, TS, Router, Vuex, CSS Pre-processors, Linter, Unit, E2E
? Use class-style component syntax? Yes
? Use Babel alongside TypeScript for auto-detected polyfills? Yes
? Pick a CSS pre-processor (PostCSS, Autoprefixer and CSS Modules are supported by default): Stylus
? Pick a linter / formatter config: Airbnb
? Pick additional lint features: Lint on save
? Pick a unit testing solution: Jest
? Pick a E2E testing solution: Nightwatch
? Where do you prefer placing config for Babel, PostCSS, ESLint, etc.? In dedicated config files
? Save this as a preset for future projects? Yes

And I use babel-plugin-import

yarn add babel-plugin-import --dev

and add config into babel.config.js

module.exports = {
presets: [
'@vue/app',
],
plugins: [
'transform-vue-jsx',
'@babel/transform-runtime',
['import', { libraryName: 'vue-antd-ui', libraryDirectory: 'es', style: 'css' }]
]
};

Then add some components into main.ts, I will get the warnings. Details can be found in the project I provide above
