I am not really sure if the cause of the error is the upgrade

Can anybody of you give me a hint what's wrong...

[ciesielskico]

Had the same problem. I deleted a component which was referenced in an index.ts file using export * from './xxx.component';

After removing that reference from index.ts the error was gone.

[maku]

@ciesielskico My problem is really strange - I created a new cli application (1.0.0-beta.31, ng4) and ported my existing application step by step (to hit what the problem is).
But in the end I could not found the problem, BUT I had an application which works.

As soon as I clone this working application (and install all dependencies via npm) the error is present again...

This is so frustrating...

[aviramga]

Hi @maku,
I also tried re-creating your issue.
I've noticed that if the typescript version is lower than 2.1.6 the build throws errors.
Could that be the issue?

[maku]

Finally I got the reason of the error. I use a library in my client project which is also under development. So I "link" it via "npm link ...".
After removing node_modules the link information is not present anymore.

The result is this very, very indifferent message.
After linking it again everything is okay....
I cannot believe it that it took so long to find the solution....

[OysteinAmundsen]

I experience the same error message. Only my project runs fine locally, but not when git-pulled down to an Ubuntu VM. This is a clean pull, so there's no linked libraries.

[OysteinAmundsen]

Found the culprit.

index.ts

export * from './file'
export * from './file2'

file.ts

import { File2 } from '.'; // Reads from index.ts

This caused some kind of recursion which Windows allowed, but Ubuntu didn't.

[carlosvillademor]

Hi all, see https://github.com/webpack/webpack/issues/4072 and the comment from @Toub, https://github.com/webpack/webpack/issues/4072#issuecomment-278626604, on how to add some logging info to help you find the culprit of your error.

[ebruner]

I got this error: crypto.js:74
this._handle.update(data, encoding);

My code had a type-o. Double check it.

[christianacca]

I hit the same error message. In my case, the problem was due to a typescript compile error.

I found useful to troubleshoot is to run tsc - this produced a meaningful typescript error rather than the "Data must be a string or a buffer" one raised by webpack

[Tryptich]

I have the same problem, I solve it with this issue 4072

[deshbandhu-renovite]

I think you have deleted service file and forgot to remove from import service export * from "./_service/index"

[cc2victoria]

I meet the same error message. In my case. it was DeletedModule not the HarmonyExportImportedSpecifierDependency moodule. I upgrade my webpack1.X to webpack3.x
