Error: Cannot find module 'babel-runtime/core-js/object/assign'

[JounQin]

• Node Version: 9.3.0
• NPM Version: 5.6.0
• koa Version: 2.4.1
• koa-wepback Version: 1.0.0

Expected Behavior

Works well without babel, I'm using typescript, so babel is unnecessary

Actual Behavior

Throw error unless I install babel-runtime manually

How can we reproduce the behavior?

remove babel-runtime dependency, then yarn dev.

add babel-runtime as koa-webpack dependency should fix this, or find another way.

2.0.0 removed babel as a runtime dependency.
