Compiling Error with node-gyp on Win10x64 and Electron

[Ironcheese]

I am trying to get font-manager installed with electron.

Current System Setup:

• Windows 10 x64
• nodejs v6.2.0
• npm 3.9.6
• Visual Studio 2015 Community (With C++)

Following output is generated when run "install font-manager"

`electron-quick-start master > $ npm install font-manager

font-manager@0.2.2 install Q:\workspace\ALEXANDER\electron\electron-quick-start\node_modules\font-manager
node-gyp rebuild

Q:\workspace\ALEXANDER\electron\electron-quick-start\node_modules\font-manager>if not defined npm_config_node_gyp (node
"C:\Users\Alex\AppData\Local\scoop\apps\nodejs\6.2.0\nodejs\node_modules\npm\bin\node-gyp-bin....\node_modules\node-g
yp\bin\node-gyp.js" rebuild ) else (node "" rebuild )
Die Projekte in dieser Projektmappe werden nacheinander erstellt. Um eine parallele Erstellung zu ermöglichen, müssen Sie den Schalter "/m" hinzufügen.

If I then start electron via "npm start" the dev tools log:

ELECTRON_ASAR.js:158 Uncaught Error: Eine DLL-Initialisierungsroutine ist fehlgeschlagen. \\?\Q:\workspace\ALEXANDER\electron\electron-quick-start\node_modules\font-manager\build\Release\fontmanager.node

Is this a node-gyp issue? Or am I missing something?

I know I'm pretty late to the party but I ran into this today. For others coming here with the same issue, you need to use something like electron-rebuild to get native modules working ( see: http://electron.atom.io/docs/tutorial/using-native-node-modules ) and is not a problem exclusive to font-manager.

What I did to get font-manager working in my electron app:

1. Install electron-rebuild as a dev dependency (npm install --save-dev electron-rebuild)
2. Create a postinstall script that runs electron-rebuild ("scripts": { "postinstall": "electron-rebuild" }})
3. Install font-manager (npm install --save font-manager)
4. Run postinstall script (npm run-script postinstall)
5. At this point, you may get an error that the cleanup task failed because it couldn't unlink a file. Simply delete the offending file manually and you'll be able to run postinstall again.
6. After electron-rebuild successfully runs, everything should be good to go.

I eventually gave up on native font modules. With each change in Node/Chromium everything would break all over again. It was taking too much of my time, so I made a package which uses pure JavaScript. It's currently being used in a production application around the world without issue.

If you're interested: https://www.npmjs.com/package/system-font-families

Thanks @rBurgett!! Your package works great in my electron project. Really appreciate your work 🙏
