Weird error after updating to 1.6.1 from 1.5.0

I'm using element-ui and after updating from 1.5.0 to 1.6.1 things started breaking and I cannot `yarn dev` anymore. Not just element-ui, things are breaking on electron-vue boilerplate side too - static images are throwing a 404 in dev mode (and not after building). I've not changed anything else other than updating this package. I've downgraded back and the error seems to go away. This is the error I'm getting:

```
ERROR in ./src/renderer/main.js
Module not found: Error: Can't resolve 'antd/lib' in '~/src/renderer'
@ ./src/renderer/main.js 276:0-32
@ multi (webpack)-dev-server/client?http://localhost:9080 webpack/hot/dev-server ./node_modules/electron-webpack/vue-renderer-entry.js ./src/renderer/main.js
```

I'm not sure why suddenly it requires `antd/lib` module where it was working fine before. Things I've done to try to fix it:

* Whitelisting element-ui:
```
"electronWebpack": {
"whiteListedModules": ["element-ui"],
},

```
* Referencing image as:
=> this doesn't load in dev build but does in production
