Hello,

I’m currently implementing deeplinks into our app using [Simon Grimm’s wonderful tutorial](https://devdactic.com/universal-links-ionic/). However, I’m having trouble setting the`URL_SCHEME`, `DEEPLINK_SCHEME`, and `DEEPLINK_HOST`. The tutorial recommends adding via cordova cli, but our project is using capacitor.

When I try to run `npm i ionic-deeplinks-plugin --variable URL_SCHEME={scheme} --variable DEEPLINK_SCHEME=https --variable DEEPLINK_HOST={host}`, I get the following npm error:

```auto
npm ERR! code EINVALIDTAGNAME
npm ERR! Invalid tag name "URL_SCHEME={scheme}": Tags may not have any characters that encodeURIComponent encodes.

```

I have tried updating npm to most recent (7.5.3), and still receive this error. Is there another way to set these variables using npm? Or, failing that, can I set these variables manually elsewhere?

Thanks!

So it turns out Capacitor [does not support CLI config variables](https://capacitorjs.com/docs/cordova/using-cordova-plugins).

Our solution to this problem was to use [Capacitor Deeplinks](https://capacitorjs.com/docs/guides/deep-links), which is considerably simpler than Cordova.
