Native module not found in win10 has new problem?

[acefeel]

I build a js file and put into opencv4nodejs native module in it, after I pkg the js file into .exe file, then I copy opencv4nodejs.node in to the exe folder, it got me an err:
PS D:\cv> ./a
pkg/prelude/bootstrap.js:1185
throw error;
^

Error: The specified module could not be found.

run node a.js is ok, node version 10.15.3 pkg version 4.4.0
it seems \\?\ is the problem? what is that?
pkg in ubuntu 18 node10 is OK.
I found there is a issue in cmake windows about pkg, but how to solve this? thanks.

I have this issue too. Is there any way to fix it?

I am also intermittently having this problem. Has anyone found workarounds or even discovered a root cause? So far only Windows 7 machines have reported this error in my app, but if others see it in Windows 10 that's concerning.

\\? seems to be a windows hack to deal with filepaths longer than 260 characters. That feels like it could be the difference on Windows 7 with others in that issue reporting Windows 8 and Windows 10 not having this problem, but I'm not sure if this is pkg-specific change or would require a hack of node's require system.

[patrickhulce]

OK in case this helps others I think this is unrelated to the \\? bit (which seems to work as intended) and this error is misleading because it's actually about missing DLLs that are required by your native node addon which can be analyzed with dependencywalker.

In my case (sharp) the Windows 7 machine was missing the C++ 2015 Redistributable library that comes baked in Windows 10 these days.
