Bug Report

Current Behavior
I can successfully compile my project with webpack. However, I can not start the compiled js file with the node order. And every time I do this node service.cjs, there will occur the error message: "Cannot find module 'multer'".

Input Code
- REPL or Repo link if applicable:

Expected behavior/code
I hope that I can run the compiled js file.

Additional context/Screenshots
Add any other context about the problem here. If applicable, add screenshots to help explain.

You need to install multer as a dependency.

@titanism
I'd tried to install multer directly for use, but this problem still exists. Moreover, the multer module is also referenced by @koa/multer, which seems to indicate that the multer module has not been correctly bundled into the packaged js file.
