Raspberry Pi で electron をインストールしようとすると以下のように落ちてしまいました。

```
> electron@7.1.2 postinstall /home/pi/test/node_modules/electron
> node install.js

@Electron 7.0.0
@Spectron 9.0.0

[electron-quick-start](https://github.com/electron/electron-quick-start) に [mocha](https://mochajs.org/) と [spectron](https://electronjs.org/spectron) をインストールして、簡単なテストを走らせてみました。
すると、以下のようなエラーが。

```
  1) Application launch
       shows an initial window:
     TypeError: waitUntilWindowLoaded Cannot read property 'isLoading' of undefined
      at waitUntil(, ) - application.js:263:17
```

実際に走らせたのは以下のコードです。
