electron-prebuilt postinstall script not finishing

It seems the `postinstall` script of `electron-prebuilt` sometimes fails to complete, resulting in a missing configuration file.

``` sh
> devtool

fs.js:549
return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
^

Error: ENOENT: no such file or directory, open '/Users/aleclarson/devtool/node_modules/electron-prebuilt/path.txt'

```

You can get around this using:

``` sh
cd $HOME/devtool/node_modules/electron-prebuilt
sudo node install.js
```

Is there something that can be done to automate this?

Or is this issue the responsibility of `electron-prebuilt` contributors?
