build crashes on polyfills not present in built-ins.json #3578
Description
Version
3.4.1
Steps to reproduce
babel.config.js
module.exports = { presets: [ [ '@vue/app', { polyfills: [ 'es6.promise', 'es6.symbol', 'es7.array', ] } ] ], }; What is expected?
build should run, or at least produce a reasonable error message
What is actually happening?
build crashes with "cannot read property 'android' of undefined"
can be "fixed" by e.g.
function getPolyfills (targets, includes, { ignoreBrowserslistConfig, configPath }) { const { isPluginRequired } = require('@babel/preset-env') const builtInsList = require('@babel/preset-env/data/built-ins.json') const getTargets = require('@babel/preset-env/lib/targets-parser').default const builtInTargets = getTargets(targets, { ignoreBrowserslistConfig, configPath }) return includes.filter(item => { return ( builtInsList[item] === undefined ) ? false : isPluginRequired(builtInTargets, builtInsList[item]) }) }
