Hi,

I’m having some problems getting with a fresh installation of Sage 9 on my Mac. I recently updated to Mojave, not sure if that’s relevant!

Basically when I run `yarn start watch` I am getting:

```
ERROR Failed to compile with 1 errors 5:19:06 PM

This dependency was not found:

* fs in ./node_modules/watch/main.js

To install it, you can run: npm install --save fs
```

I have tried to run the dependency installation it metions, it does a bunch of stuff, but still I get the same error afterwards.

Does anyone have any clue??

Thaks

`yarn start watch` isn’t documented and is not how you want to start the development session

Do `yarn start`

Thanks… no idea why I thought it was that then!
