Repro steps

Updated local version of the CLI to the latest version and updated npm to latest.
Fixed all dependency errors it was complaining about and then update core to latest.

The log given by the failure

This seems like a bug but we'll need to look at a reproduction to find and fix the problem. Can you setup a minimal repro please?

You can read here why this is needed. A good way to make a minimal repro is to create a new app via ng new repro-app and adding the minimum possible code to show the problem. Then you can push this repository to github and link it here.

This might be related to your directory structure so its really important to get an accurate repro to diagnose this.

I am having the same issue. Upgrading from 0.8.1 to 0.8.3, building or serving with or without --aot give the error:

Cannot find module 'merge-descriptors'
If I proceed to add that module manually, I get another error:
Cannot find module 'finalhandler'
And then again:
Cannot find module 'path-to-regexp'
And again:
Cannot find module 'methods'
Yet again:
Cannot find module 'content-disposition'

Then I honestly stopped and reverted back to 0.8.1.

Sure thing, i will get on that. If this does not work, i will share the full repo.

After some messing around with creating a repro app and moving code over i found that one of the script entries in my angular.json file pointing to a folder and not a file. Removing this fixed the error.
