Electron-builder: __shim.js not found upon launch

[koopa]

• Version: 19.33.0
  
  
• Target: win32.nsis

After the setup when I try to launch the exe, I get this trace:

Error: Cannot find module 'C:\Users\kon\AppData\Local\Programs\vt\resources\app.asar\__shim.js'
    at Module._resolveFilename (module.js:470:15)
    at Function.Module._resolveFilename (O:\kon\AppData\Local\Programs\vt\resources\electron.asar\common\reset-search-paths.js:35:12)
    at Function.Module._load (module.js:418:25)

    at tryModuleLoad (module.js:447:12)
    at Function.Module._load (module.js:439:3)

In app.asar:

$ pwd
/c/Users/kon/AppData/Local/Programs/vt/resources

$ asar ef app.asar ___shim.js
O:\kon\AppData\Roaming\npm\node_modules\asar\lib\filesystem.js:144
    if (info.link && followLinks) {
            ^
TypeError: Cannot read property 'link' of undefined

However:

$ asar l app.asar | grep -C5 '__shim'
\.cache\4e1a5069de66f1b2f52927c2388cdfb0756c1285\fad86a314ecc0e771f27f0ad3e5d827512047ab9
\
\
\
\
\__shim.js
\package.json
\node_modules
\node_modules\amd-name-resolver
\node_modules\amd-name-resolver\index.js
\node_modules\amd-name-resolver\package.json

I am wondering if those multiple \ are normal, seems a bit suspicious. I also tried reinstalling asar on this machine with the same result.
Then I tried to re-create the app.asar with __shim.js copied manually and replaced this with the previously generated app.asar. Now the application started and worked.

Any suggestions how to get to the bottom of this? Thanks!

I am having this issue as well over at https://github.com/willyb321/media_mate

I'm getting this on Mac after upgrading to High Sierra and updating to the latest version (19.35.0) to avoid the hang during DMG creation. The build succeeds, but then I get the Uncaught Exception: Error: Cannot find module '/Users/brandon/code/project-name/release/Project.app/Contents/Resources/app.asar/__shim.js error upon launch.

Thanks to you both for sharing the info.
@willyb321 I saw you downgraded electron-builder, was that related to this issue and did it fix it?

[willyb321]

@koopa yeah - it was related and downgrading seems to have fixed it.

This is happening to me as well - it started happening for me with version 19.30.3

Looks possibly related to the logic handling the ASAR packaging. I'm going to try to dig into this further and see if I can determine the exact change.

Perhaps @develar you may have a better idea of what the issue is?
