Post-install extraction keeps failing when running npm install

We have integrated webviewer in our react app, but we keep running into an issue where @pdftron/webviewer-downloader's post-installation script keeps failing randomly.

The build scripts fail with the error:

Extracting WebViewer...events.js:187
      throw er; // Unhandled 'error' event
      ^

Our pipeline is simply:

npm i
npx @pdftron/webviewer-downloader --path ./public/webviewer

It also happens once in a while installing locally, with the same error message. Do you have any idea how to fix this? Rerunning failed pipelines is a bit annoying...

We have the same issue at our company, it's very annoying!

Hi guys,

Thanks for bringing this to our attention! I just tried webviewer-downloader multiple times locally but wasn't able to reproduce the issue. It's kind of unfortunate that the issue seems to be from a library that webviewer-downloader depends on, which means we might not be able to fix this issue.

I found some similar issues in that github repo thejoshwolfe/yauzl#69, thejoshwolfe/yauzl#98 and thejoshwolfe/yauzl#60.

However these issues might be unrelated since I don't think we are using Mac Archive Utility to create the WebViewer.zip. I will take a look at this issue and see if I'm able to figure something out.

In the meanwhile, we will investigate if it's feasible to put WebViewer worker files on npm so that you don't need to use the downloader to download them in your pipeline.

Sorry for the inconvenience!

For our pipeline, we are using the node official Docker image node:12.14.0. Hope that helps!

Hi guys, we made an attempt to fix this issue. Can you try the latest version and see if the issue is fixed? To install the latest @pdftron/webviewer-downloader in your pipeline please make sure that git is installed as well in that environment.

After a couple of test, it seems to work fine now. Thanks!

We still face this issue on a regular basis running yarn install in our github action pipeline.

I remove node v12 from the pipeline. No issues with v10 so far
