running `yarn start` from root

results in:

```auto
    yarn start
    yarn run v1.22.4
    $ lerna run start --stream
    lerna notice cli v3.22.1
    lerna info versioning independent

    lerna ERR! yarn run start exited 7 in 'app'

```

if I `cd packages/app` and run `yarn start` it works fine.

Hmm it seems to be related to the `--stream` option of lerna, removing it allows everything to work, but with no console output.

```json
        "start": "lerna run start"    

```

hi there,

would you mind filing an issue on this here:

> **[GitHub - netlify/cli: Netlify Command Line Interface](https://github.com/netlify/cli/)**
>
> Netlify Command Line Interface. Contribute to netlify/cli development by creating an account on GitHub.

that is really the best place for this - sorry we’ve been sluggish to get you answers, but we’re not quite sure what to suggest. the folks on the CLI team will likely have more insight for you.
