(Windows Only) Cannot recognized `\\?\` prefix in unpacked path

[codehz]

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 am having a similar issue I just compiled the hello from node nan and required it from an Asar and got the same error. I added asar.unpacked on *.node or let the .node in the packed file and got the behaviour.

I also only got this behaviour on some windows 7 machines, windows 8 and 10 worked even with the .node inside the asar.

I did an app without asar run trhough electron and I'm still getting the "?\PATH" not found so I don't think is an assar issue, it's maybe an electron or node issue

Seems to be related https://github.com/nodejs/node/issues/2964

+1... any update ? thanks

What is the current status of this? It seems to me that Node is modifying the path to prepend the //?/ prefix in order to trigger a Microsoft hack to support real long filenames. However, something in electron-asar doesn't understand/support this. I have no workaround to this.

Why the wontfix label? What's the workaround?

It is not a bug of asar after my 2 day digging. In my case, I use node-java.It throw flowing error:

Uncaught Error: %1 is not a valid Win32 application.

I flow laggingreflex's idea. https://github.com/soldair/node-qrcode/issues/22 native module can not be load because it's dependences was missing. U can use dependencywalker to found out what denpendences was missing, and try to copy to path of entry or add to system path environment variable!

I got this problem The specified module could not be found. I read a lot of issue and then remove the asar option. It worked....But Why this happened? Only on Windows

[mridah]

@JackieLs how did you remove the asar ??

[JackieLs]

@mridah Maybe my description is not very accurate.Just set it false.

module.exports = {
	appVersion: pkg.version,
	arch: ['x64'], // ia32, x64, armv7l, all
	asar: os.platform() !== 'win32', //when on win32 is false.default is true.
	dir: path.join(__dirname, '../app'),
	icon: path.join(__dirname, '../app/icons/icon'),
	ignore: /renderer/,
	out: path.join(__dirname, '../builds'),
	overwrite: true,
	platform: process.env.PLATFORM_TARGET,
}

[mridah]

@JackieLs so I can use asar: false in module.exports. right ?

[JackieLs]

the module.exports is just to export the config.You can set the config in any where.

I don't think this is a denpendency issue. this happens only when I bundle my app with asar option on.
