## `require('electron').xxx` is undefined.
When using Electron's built-in module you might encounter an error like this:
```
> require('electron').webFrame.setZoomFactor(1.0);
Uncaught TypeError: Cannot read property 'setZoomLevel' of undefined
```
This is because you have the npm `electron` module installed either locally or
globally, which overrides Electron's built-in module. You can to either remove
the module, or rename it.
