thx.

finally, my temporary solution for development environment:

1. create /lib/common.js and dynamic-import all the dynamic components

const dynamics = () => [
  import('../components/hello1'),
  import('../components/hello2'),
  import('../components/hello3'),
  import('../components/hello4')
]

2. i don't use above function, but every page import common.js file

import '../lib/common'

Thats it. the common.js file helps webpack/bootstrap to create a correct chunks mapping list during development environment, so temporary say bye to those errors

script.src = __webpack_require__.p + "" + ({"0":"main.js","1":"bundles/pages/_error.js","2":"bundles/pages/_app.js","4":"chunks/components_hello1_2118a1d2a4935c3fb995190faa8dbd95","5":"chunks/components_hello4_4c239e4dc0cd2618c3e111f41c791a1c","6":"chunks/components_hello3_693127fc8d6e8d58856e50574974e451","7":"chunks/components_hello2_23440136ce0953a1f9b2387ab3c13db4","8":"bundles/pages/index.js"}[chunkId]||chunkId) + ".js";

for production, just comment out import '../lib/common' or just leave it here
