NodeRT: could not find assembly

Question

I am writing an electron app with electron-windows-notifications which is dependant on NodeRT.

As I try to install my project, I get following error for each of @nodert-win10 dependencies:

> if not defined npm_config_node_gyp (node "C:\Applications\nodejs\node_modules\npm\bin\node-gyp-bin\\..\..\node_modules\node-gyp\bin\node-gyp.js" rebuild --msvs_version=2015 )  else (node "" rebuild --msvs_version=2015 )
Building the projects in this solution one at a time. To enable parallel build, please add the "/m" switch.

Please, can you help me?

I was also getting following error:

I followed the following steps:

1. Create a folder(check building.gyp file for path)

   %ProgramFiles(x86)%/Microsoft Visual Studio 14.0/VC/lib/store/references

2. Copy file platform.winmd from

   C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\VC\Tools\MSVC\14.16.27023\lib\x86\store\references

3. Copy file Windows.winmd from

   C:\Program Files (x86)\Windows Kits\10\UnionMetadata\10.0.17763.0

did the trick to fix the "platform.winmd", "Windows.winmd" error for me!

Answer 2

For anyone else dealing with this issue. I fixed it by copying Windows.winmd

from

C:\Program Files (x86)\Windows Kits\10\UnionMetadata\10.0.16299.0

to

C:\Program Files (x86)\Windows Kits\10\UnionMetadata
