Investigation update:

When set the node_modules as symlink, and the run yarn build, the .next/server/pages/_document.js contained the react.producion.min.js

Refer to https://github.com/facebook/react/issues/16029#issuecomment-570912067 Set the webpack config in next.confg.js

config.externals = [
  ...config.externals,
  {
    react: {
      root: 'React',
      commonjs2: 'react',
      commonjs: 'react',
      amd: 'react'
    },
    'react-dom': {
      root: 'ReactDOM',
      commonjs2: 'react-dom',
      commonjs: 'react-dom',
      amd: 'react-dom'
    }
  }
]

The build process is success.

The next.js version is 9.5.4-canary.5
