1.1. Official methods
Install rtop, the ReasonML toplevel interpreter in Debian oldstable [1] Stretch 9.9. It’s young (may 2016) and not packaged (yet ? [2]).
Official method, via npm : ~250 dependances for npm in Debian… let’s try the alternative method : yarn.
The yarnpkg is not installed by apt, conflicts in dependances :
The following package contain unsatisfied dependances : yarnpkg : Depends on: node-babel-runtime (>= 6.26.0) but 6.18.0-1 must be installed [… 8 lines …] Depends on: node-node-uuid (>= 3.0.1) but 1.4.0-1 must be installed E: Impossibl to fix the problems, some broken packages are in "keep" state.
That lets us with npm, but surprise npm install -g reason-cli@latest-linux fails Grmbl :-/

1.2. Via OPAM the OCaml Package Manager
The official Reason website don’t mention other methods but there’s still the OCaml Package Manager : opam.
opam Install :
# apt install opamCatalog update and rtop install :
$ opam init (1)
$ opam install rtop| 1 | With Debian Buster, this step needs to be augmented a bit : apt install mccs opam init --solver=mccs |
$ rtop

2.1. Méthodes officielles
Installation d' rtop, l’interpréteur ReasonML, dans Debian oldstable [3] Stretch 9.9. C’est jeune (mai 2016) et pas packagé [4] (ça commence…).
Méthode officielle, via npm. Y’a ~250 dépendances pour npm dans Debian… voyons la méthode alternative : yarn.
Le paquet yarnpkg n’est pas installé par apt, conflit de dépendances :
Les paquets suivants contiennent des dépendances non satisfaites : yarnpkg : Dépend: node-babel-runtime (>= 6.26.0) mais 6.18.0-1 devra être installé [… 8 lignes …] Dépend: node-node-uuid (>= 3.0.1) mais 1.4.0-1 devra être installé E: Impossible de corriger les problèmes, des paquets défectueux sont en mode « garder en l'état ».
Bon bah allons-y pour npm… Mais surprise : erreur à l’exécution de npm install -g reason-cli@latest-linux Grmbl :-/
error: Error: EACCES: permission denied, mkdir '/usr/local/lib/node_modules/reason-cli/3______________________________________________' npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! reason-cli@3.3.3-linux-1 postinstall: `node ./esyInstallRelease.js` npm ERR!

2.2. Via OPAM l’OCaml Package Manager
Le site officiel n’indique pas d’autre méthode d’installation, mais il reste le gestionnaire de paquet d’OCaml : opam.
Installation d' opam :
# apt install opamMise à jour du catalogue, et installation d' rtop :
$ opam init (1)
$ opam install rtop| 1 | Avec Debian Buster, cette étape doit être augmentée un peu : apt install mccs opam init --solver=mccs |
$ rtop
