electron app not found wrtc

[josselinchevalay]

Hello guys,

i implement electron in my web app and try to run but i have this error.

Error: Cannot find module '/home/josselin/development/telescope/node_modules/wrtc/build/wrtc/v0.0.61/Release/electron-v1.6-linux-x64/wrtc.node'

i try to install leveldown and wrtc manually with npm install --save wrtc leveldownbut not works againt

regards

Ensure the electron-v1.6-linux-x64 diectore exists, if not create it and then move wrtc.node into it.

You'll likely get an error about it being built for the wrong version at which point you need to do some funky arcane shit with electron-rebuild. from then on it will work but dont even think about trying to package it up using electron-packer because that just breaks everything.

Someone who knows what they are doing might be able to actually resolve it, but I threw a weekend into it and that's as far as I got.

Abandon hope all ye who enter here

now i have that :

was compiled against a different Node.js version using
NODE_MODULE_VERSION 48. This version of Node.js requires
NODE_MODULE_VERSION 53. Please try re-compiling or re-installing

This solved @kyledrake's issues https://github.com/electron/electron/blob/master/docs/tutorial/using-native-node-modules.md let me know if it works for you.

hi i test your proposal to build native module with electron-rebuild

after a first error because i need to add libssl-dev now i have that

@kyledrake could you tell us how you solve this issue?

[daviddias]

wrtc shouldn't be a issue anymore with #884. Now onto the remaining issues, please track it in #843
