Bonjour,

Je viens d'installer "sass" avec npm et voici les messages retournés par le terminal:


Le moins qu'on puisse dire, c'est que c'est pas très claire pour un débutant, alors est ce quelqu'un pourrait me dire quelles actions je dois faire ?

D'avance merci.

[Marco46]

Il faudrait aussi savoir ce que te demande exactement ton cours open class room.

Il faudrait aussi connaître les versions de node et npm installées sur ta machine (node -v et npm -v dans un terminal)

Tu as installé ce package qui est à priori lié à Dart, c'est ce que tu voulais ?

Pour le reste, les messages indiquent que :
- tu n'as pas initialisé correctement un package.json (npm init dans un terminal) avant d'exécuter l'installation mais ça ne semble pas bloquant (warning et pas erreur)
- il t'a créé un package-lock.json lors de l'installation de sass ce qui est normal, il te faudra commit ce fichier avec le reste
- le package fsevents qui doit être une dépendance de sass ne supporte pas ta plateforme (ton OS), je ne sais pas ce que ça peut donner à l'exécution
- les 4 derniers warnings concernent le détail de ton package.json qui n'est pas correctement initialisé (il te dit que certains champs sont absents alors qu'il est de bon ton de les remplir) mais rien de bloquant.


Donc au final tout dépend de ce qui est demandé dans ton cours. A priori tu devrais pouvoir le continuer normalement il n'y a pas d'erreurs seulement des warnings.

[haddocks]

Merci pour toutes ces infos.

Le cours en question ne donne pas de version, il dit seulement a quoi ça va servir.

Ce que j'ai installé:
Node js: 14.3.0
npm: 6.14.5
sass: 1.26.5

Si "commit" veut dire valider, alors comment fait-on pour valider le fichier Package-lock.json ?
Et enfin, comment fait-on pour remplir les champs du fichier package.json ?

Merci encore.

[Marco46]

Commit c'est lié à Git, cf la FAQ. Pour les besoins de ton tuto tu peux ignorer ça et ignorer le package-lock.json.

Pour modifier les champs du package.json ben tu ouvres le fichier et tu les modifies.

Ca n'a rien d'obligatoire, il s'agit de warnings pas d'erreurs.

Tu es bloqué quelque part ? Pour moi tu peux tout simplement continuer ton tuto sans te préoccuper de ces messages.

[haddocks]

Merci Marco46,
Je vais avancer et je verrai comme t'as dit.

[haddocks]

Bonjour,

J'y suis presque mais ça bloque à cette étape:


et voilà ce que j'obtiens:



Sass est pourtant bien installé

[haddocks]

Par curiosité j'ai tester un "sass --version" à la racine et dans mon repertoire
Çà colle pas avec la photo au début du poste qui dit que sass est bien installé. j'ai même le fichier Package-lock.jason.

[Marco46]

Ton OS ne détecte pas les modules installés dans ton-projet\node_modules\.bin\ (problème de PATH).

Place toi à la racine de ton projet et essaie d'exécuter node node_modules\.bin\sass --version.

Sinon le plus simple reste d'ajouter un script dans ton package.json. Tu dois y avoir une section "scripts" tu lui en ajoutes un :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
 
    "scripts": {
        "sass": "sass --version"
    },

que tu exécutes via ton IDE ou dans ta console en te plaçant à la racine du projet puis npm run sass.

Si ça marche tu peux y ajouter la commande initialement souhaitée :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

5
 
    "scripts": {
        "sass": "sass --version",
        "sass::watch": "sass --watch scss:css"
    },

Que tu exécutes via npm run sass::watch.

Sinon dans tes posts évite les screenshots, poste plutôt des copiés / collés de la console c'est plus simple à traiter derrière.

Donc je suis pas allé plus loin.

[Marco46]

Quand tu as une erreur npm ERR! code EJSONPARSE sur ton package.json c'est que tu t'es planté quelque part en le modifiant.

Ici tu as oublié la virgule pour séparer la nouvelle entrée que tu as ajouté aux scripts.

Avant

Code :

  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
    "sass": "^1.26.5"
  },

Après avec correction

Code :

5
 
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "sass": "^1.26.5"
  },

Pour ton point n°1 tu dois avoir un problème avec ton installation de node / npm sous windows, ça ressemble beaucoup à ça. Il faut savoir que la plateforme standard pour développer en web c'est linux et pas windows. Beaucoup de packages sont très mal testés sous windows donc utiliser cet OS c'est prendre un certain risque.

[Marco46]

Je me rends compte à la relecture que tu n'as pas compris ce qu'il fallait mettre dans ton script.

Il te faut mettre plutôt

Code :

"scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "sass": "sass --version"
  },

et non la version du package qui ne sert que dans la propriété dependencies.

Si ça fonctionne tu peux ajouter la commande de watch :

Code :

"scripts": {

Je voudrait bien recommencer l'install de tous ça en te montrant ce qu'il se passe à chaque étape, mais comment remettre tout à plat ?

[Marco46]

Désinstalle et réinstalle node (et pas npm qui est contenu dans node), tu as clairement un soucis à l'installation sur la gestion du PATH.

[haddocks]

Bonjour Marco46,

Je vais laisser ça de côté un moment, j'ai d'autres choses sur lesquels je voudrais avancer.

Merci.

[haddocks]

Bonjour,

j'ai pas trouvé comment désinstaller NodeJS.
j'ai lancé un fichier msi de cette adresse:
https://www.npmjs.com/get-npm

J'ai sélectionner l'option "installer les outils"



voilà le fil du reste de l'install:

Bonjour,

Apparemment il manque des dépendances a Jquery pour l'instal de boostrap.

Comment on fait ça ?

En revanche pour sass, j'ai peut-etre trouver la solution car j'ai installé koala: http://koala-app.com/

Bonjour à tous.

J'ai cherché de mon coté après avoir eu le même problème. La réponse est assez simple en fait et même déroutante , il suffit d'installer "sass" de manière générale.
"npm install -g sass"
J'espère que cela marchera de votre coté, merci à vous.
