Multiple instances of Mobx in v4

[Hypothesis-github]

I am using

 "mobx": "^4.3.1",
    "mobx-react": "^5.2.3",
    "react": "16.3.1",
    "react-native": "~0.55.2",
    "react-native-router-flux": "^4.0.0-beta.31"

and I have gotten the multiple instances since I was already using mobx in react native for routing.
I tackled this ( or at least I think I tackled this) by the instruction provided by the author of react-native-router-flux, which is to search for duplication of mobx in modules, and sure there were 2 extra in react-native-router-flux's node module folder.
package.json also contained a lower version of mobx and mobx-react , I believe v3 or mobx.
so I deleted both folders and the dependency in the package.json and refreshed.
the warning of multiple instances went away. but I have some concerns now.

1. Npm install brings back both folders of mobx and mobx-react to the module folder of react-native-router-flux. How can I make sure these 2 dependencies will never come back since I deleted the line in react-native-router-flux's package.json as dependency but they still get installed after npm install.

2. Why the mobx and mobx-react exist in the module folder of react-native-router-flux, and if of course they are handling some actions will they be interrupted because I have deleted the folders manually ?

Your version of react-native-router-flux ^4.0.0-beta.31" doesn't properly include mobx which is fixed in ^4.0.0-beta.32. This problematic version is the default on npm so, at this time, you'll need to manually upgrade to the latest and this issue is gone.

The creator of mobx outlines the method for properly including mobx in code intended for shared libraries

@aTable the latest is 4.0.0-beta.31, I cannot see 32 in the release list https://github.com/aksonov/react-native-router-flux/releases

I guess it's an unofficial beta at this stage

If for some reason you don't feel like bumping the version, I was able to workaround this using yarn and resolutions, as outlined here.

Latest version no longer uses mobx, closing it.
