ionic build command not working

Here is my ionic info:

```
[WARN] Bad integration name: gulp

Ionic:

ionic (Ionic CLI) : 4.12.0 (C:\Program Files\nodejs\node_modules\ionic)
Ionic Framework : ionic1 1.3.5
@ionic/v1-toolkit : 1.0.22

Cordova:

cordova (Cordova CLI) : 9.0.0
Cordova Platforms : android 7.0.0
Cordova Plugins : no whitelisted plugins (15 plugins total)

System:

NodeJS : v10.15.3 (C:\Program Files\nodejs\node.exe)
npm : 6.4.1
OS : Windows 10
```

I am trying to build my ionic v1 app with the latest cli. I keep getting this error:

```
ionic-v1 build --verbose
[12:23:00] Cannot load gulp: ReferenceError: internalBinding is not defined
[12:23:00] Cannot load gulp: ReferenceError: internalBinding is not defined
[12:23:00] Cannot run sass task: missing in gulpfile.js
[12:23:00] Cannot load gulp: ReferenceError: internalBinding is not defined
```

Start by reproducing `ionic-v1 build --verbose` with the reported Ionic CLI, NodeJS, Cordova, and Windows versions, then inspect how the command loads `gulpfile.js`. Done means the Ionic v1 build completes without the `internalBinding` or missing Sass task errors.
