Cannot load native extension when using asar

[codehz]

ELECTRON_ASAR.js:158
Uncaught Error: The specified module could not be found.
?\C:\Users\AppData\Local\Temp.tmp.node

And I can found it in this path..

I think the \\?\ is unnecessary..

It appears only when I use this option --asar=true

Which version of electron-packager are you using?

7.3.0

What CLI arguments are you passing? Alternatively, if you are using the API, what parameters are
you passing to the packager() function?

electron-packager . "VizMusicPlayer" --out=dist/win --platform=win32 --arch=x64 --version=1.2.7 --icon=build/icon.ico --asar=true

What version of Electron are you building with?

1.2.7

What is the host platform are you running electron-packager on?

Windows 10 x64

What target platform(s)/architecture(s) are you building for?

Windows x64

Is there a stack trace in the error message you're seeing?

(RUNTIME, Electron Renderer Process)

ELECTRON_ASAR.js:158
Uncaught Error: The specified module could not be found.

So... do you use electron-builder or electron-packager — electron-userland/electron-builder#580 ? It seems it is your app issue, not packaging tool issue.

@develar it's pretty obvious from the link that this person uses electron-packager, not electron-builder.

@codehz if you use asar, you need to whitelist native extensions like sharp (they do not work, see the Electron docs for why). Check out the --asar.unpack parameter. According to another section in the same Electron docs, try --asar.unpack=*.node (I have not tested it though).

@malept
I have try to add --asar.unpack=*.node, but Still Not Working.

ELECTRON_ASAR.js:158 Uncaught Error: The specified module could not be found.
\\?\D:\x\desktop\VizMusicPlayer\dist\win\Viz Music Player-win32-x64\resources\app.asar.unpacked\node_modules\sharp\build\Release\sharp.node

I think \\?\ is the core problem....\\?\ prefix should be delete

[malept]

Try electron-packager 7.2.0 and use --asar-unpack instead of --asar.unpack. There was a change to asar options in 7.3.0 but it shouldn't have impacted functionality.

[malept]

Also, with electron-packager 7.3.0, don't specify --asar=true and --asar.unpack=*.node at the same time.

[codehz]

I have used below(7.3.0)

> electron-packager . "Viz Music Player" --app-version=0.0.1 --prune --out=dist/win --platform=win32 --arch=x64 --version=1.2.7 --icon=build/icon.ico --version-string.CompanyName="CodeHz.one" --versio
n-string.ProductName="Viz Music Player" --version-string.FileDescription="Viz Music Player" --overwrite --asar.unpack=*.node

(same as before)
and now using 7.2.0 try below

> electron-packager . "Viz Music Player" --app-version=0.0.1 --prune --out=dist/win --platform=win32 --arch=x64 --version=1.2.7 --icon=build/icon.ico --version-string.CompanyName="CodeHz.one" --versio
n-string.ProductName="Viz Music Player" --version-string.FileDescription="Viz Music Player" --overwrite --asar=true --asar-unpack=*.node

(Not work, same as before)
and this

> electron-packager . "Viz Music Player" --app-version=0.0.1 --prune --out=dist/win --platform=win32 --arch=x64 --version=1.2.7 --icon=build/icon.ico --version-string.CompanyName="CodeHz.one" --versio
n-string.ProductName="Viz Music Player" --version-string.FileDescription="Viz Music Player" --overwrite  --asar-unpack=*.node

The last one does work, but it does not used asar...

[malept]

I'm not seeing a difference between the second and third command.

[codehz]

Sorry, I have removed --asar , but forget to update comment....

[malept]

Yes, for electron-packager 7.2.0 and below, it is required to use --asar if you want asar support.

This seems like a problem with the asar module. Electron Packager does not transform the options that are passed to the asar module at all.

[drFabio]

I can confirm that is an Asar issue not electron-packager issue, I am using asar programatically and having the same behaviour. Also I am having this issue on windows 7 but not on windows 10

[vuamitom]

Please note that this same error can be thrown if dll dependencies are not found for the native node module.

Details are in last comment on

electron/asar#129

After much searching and reading documentation --asar.unpack=*.{node,dll} on the electron-packager cli did the trick for me. Make sure you are rebuilding sharp as required before packaging.
