Error with dependencies

I installed react and react-nom packages to a meteor app. the app crashed complaining about the react version + asking for react-addons-transition-group. Right now, here is the installed packages

{
  "name": "meteor",
  "private": true,
  "scripts": {
    "start": "meteor run"
  },
  "dependencies": {
    "babel-runtime": "^6.20.0",
    "bcrypt": "^1.0.3",
    "meteor-node-stubs": "~0.2.4",
    "react": "^16.2.0",
    "react-addons-pure-render-mixin": "^15.6.2",
    "react-dom": "^16.2.0",
    "simpl-schema": "^1.4.1"
  }
}

Here is the error message

I try to install this react-addons-transition-group but it does not change. Plus I don’t see why I would need a previous version of React / React-Dom. Any idea ?

I haven’t used React with Meteor before but I think the React packages from atmosphere (like react-runtime) aren’t recommended anymore and aren’t up to date.

The Guide currently says to import everything you need from npm and doesn’t mention the atmosphere packages
