解决办法：

修改package.json scripts ionic:serve

ionic-app-scripts serve 后面添加 --max_old_space_size=8192

{
  "name": "xxx",
  "author": "xxx",
  "homepage": "xxx",
  "private": true,
  "scripts": {
    "clean": "ionic-app-scripts clean",
    "build": "ionic-app-scripts build",
    "lint": "ionic-app-scripts lint",
    "ionic:build": "node copy-env-config.js --env prod | node --max-old-space-size=8192 ./node_modules/@ionic/app-scripts/bin/ionic-app-scripts.js build",
    "ionic:serve": "node copy-env-config.js --env dev | ionic-app-scripts serve --max_old_space_size=8192"
  },
  ...
}

4096不够的话就可以用8192试试
