I haven’t been coding for long, so forgive me if this is a little long winded ( I think I have a solution to this issue ):

I’m using Electron v1.4.5 & node v7.0.0 & I’m getting this error: Error: Module version mismatch. Expected 50, got 51.

In case it helps understand this a little further, I think the 50 in Expected 50, got 51 relates to the following:

cd node_modules/electron/dist/Electron.app/Contents/MacOS
./Electron --abi`
//50

And the 51 in Expected 50, got 51 relates to this:

node -p process.versions
//returns:
{ http_parser: '2.7.0',
  node: '7.0.0',
  v8: '5.4.500.36',
  uv: '1.9.1',
  zlib: '1.2.8',
  ares: '1.10.1-DEV',
  icu: '57.1',
  modules: '51',
  openssl: '1.0.2j' }

So, to get Electron & NodObjC working again, run this in the root of your project directory:

npm rebuild --runtime=electron --target=1.4.5 --disturl=https://atom.io/download/atom-shell --abi=50

The --target you can get from your project, like this:

cd node_modules/electron/dist/Electron.app/Contents/MacOS
./Electron --version
// which for me returns 1.4.5

and the --abi you can get from your project too, like this:

cd node_modules/electron/dist/Electron.app/Contents/MacOS
./Electron --abi`
// which for me returns 50

This worked for me, and I was pretty happy with myself !

Just for completeness, here is the original full error:

Hope this helps you guys (until Electron & Node get there versions synced)

Any info/workaround/fix on this? 😕

I think the reason is that node hasn’t updated v8 to 5.1+ yet, while Electron has.

At least in node 6.3.0:

$ node -p process.versions
{ http_parser: '2.7.0',
  node: '6.3.0',
  v8: '5.0.71.52',
  uv: '1.9.1',
  zlib: '1.2.8',
  ares: '1.10.1-DEV',
  icu: '57.1',
  modules: '48',
  openssl: '1.0.2h' }
