When I try to build my app for production, I get the following errors:

I'm using the 6.3.2 version.

I'm importing it on a shared module, and exporting it to the other modules:

Even if I don't use it on any component/page, I get the error just from importing it.

Weird things:

• It was working at least until last week (last successful deploy);
• It works on Windows machines, but I get these error in Linux environments;

Searched a lot and got nothing.

Any help?

Thanks in advance.

I got this error today as well.

It looks like the "latest" version of the pdfjs-dist npm went from version 2.5.207 to 2.6.347 a day ago.

Setting pdfjs-dist back to the previous version fixed the errors for me i.e. add this line to your package.json dependencies:
"pdfjs-dist": "2.5.207",

you're my savior thank you..

Same here
@markabrahams unfortunately that doesn't solve it because it still installed pdfjs-dist under ng2-pdf-viewer separately

I only found pdfjs-dist on package-lock.json

[danzrou]

well, its probably a difference between how yarn and npm resolve dependencies.
Using npm actually did not add an additional pdfjs-dist dependency under ng2-pdf-viewer, however, yarn did

noted try to installed pdfjs-dist separately, got error on importing ng2-pdf-viewer as Cannot find module 'ng2-pdf-viewer' or its corresponding type declarations.```

[danzrou]

the real solution here would be moving them from dependencies into peerDependencies and exact version

[almothafar]

I got the same issue, adding "pdfjs-dist": "2.5.207", to package.json with npm solved my issue, what I did exactly is I added this, remove the package-lock.json file and node_modules folder, then I did run npm i, that did fix my issue.

tried, but still got error on importing PdfViewerModule, as Cannot find module 'ng2-pdf-viewer' or its corresponding type declarations.ts(2307) in module, how did you import it in module ?

[almothafar]

@hafizihamid just like what documentations says:

import { PdfViewerModule } from 'ng2-pdf-viewer';

[sandu2d]

@danzrou Did you find a solution for yarn?
Is it possible to fix depencies in a project with yarn?

In yarn.lock I have:

ng2-pdf-viewer@^6.3.2:
  version "6.3.2"
  resolved "https://registry.yarnpkg.com/ng2-pdf-viewer/-/ng2-pdf-viewer-6.3.2.tgz#07189207893ceb4c086e9b6ebd74fdbb31982af1"

  dependencies:
    "@types/pdfjs-dist" "^2.1.4"
    pdfjs-dist "^2.4.456"
    tslib "^1.10.0"

And it is installing:

pdfjs-dist@^2.4.456:
  version "2.6.347"
  resolved "https://registry.yarnpkg.com/pdfjs-dist/-/pdfjs-dist-2.6.347.tgz#f257ed66e83be900cd0fd28524a2187fb9e25cd5"

@sandu2d in yarn I think there is something called "resolutions":
Try:

"resolutions": {
    "pdfjs-dist": "2.5.207"
  }

This! This solves the issue when using npm. Thank you very much @markabrahams

But it would be interesting if ng2-pdf-viewer solved it out of the box.
I'm guessing if the correct version is set on the package.json file it would fix it.

[sandu2d]

@almothafar Yes, it worked. Thank you!

export class AdminModule {}

I have

• deleted package-lock.json file
• deleted entire node_modules folder
• reinstall npm

on my local upon running ng build --prod the warning message as below appear

don't think as a big issue as it is just warning

I am deploying this code on gitlab pipeline, and upon building pipeline, error as below appear

I am not sure what seems to be the problem during this build pipeline as my local seems to be working fine,

kindly help

@farhanramli-work
Before you do your steps, which what exactly I did, did you specify or "force" package pdfjs-dist to version 2.5.207?

npm install [email protected] --save

You should be having this ("pdfjs-dist": "2.5.207") in your dependencies in package.json.

[farhanramli-work]

@almothafar

already done the given steps

[brainwind-software]

@farhanramli-work
You added:

"pdfjs-dist": "^2.5.207",

but you have to add:
"pdfjs-dist": "2.5.207",

And I would add it before 'ng2-pdf-viewer'

[almothafar]

@farhanramli-work Oh I didn't see the package.json file you posted, but yes as what @brainwind-software said, you need to remove ^, this will install the latest of 2.x so it will install 2.6.347, the problem in 2.6.347 and you need 2.5.207 to fix it.

[Rahul-kalsha]

I got the same issue, Need to add a dependencies library, and the issue will be fixed for me.
"@types/pdfjs-dist": "~2.0.1", "ng2-pdf-viewer": "^6.3.2"

OR else decrease ng2-pdf-viewer version number and add pdfjs-dist
"pdfjs-dist": "~2.5.207", "ng2-pdf-viewer": "~5.3.4",

[rahul-network]

@Rahul-kalsha The fix you have provided worked properly. Thanks for saving our lot of time.

[sraza295]

@markabrahams Thanks bro you saved my day

[narendrasinghrathore]

I got the same issue, Need to add a dependencies library, and the issue will be fixed for me.
"@types/pdfjs-dist": "~2.0.1", "ng2-pdf-viewer": "^6.3.2"

OR else decrease ng2-pdf-viewer version number and add pdfjs-dist
"pdfjs-dist": "~2.5.207", "ng2-pdf-viewer": "~5.3.4",

Not working.
