npm WARN… nécessite un pair de… mais aucun n'est installé. Vous devez installer vous-même les dépendances homologues

J'ai essayé d'exécuter un projet téléchargé depuis github . Malheureusement, au cours npm installdes avertissements suivants ont été affichés. J'ai essayé de changer la version en fonction de cette question . Cependant, j'ai eu un problème, car certains packages nécessitent plusieurs versions d'autres packages. Considérez ces deux lignes:

npm WARN @angular/cdk@2.0.0-beta.10 requires a peer of @angular/core@^4.3.0 but none is installed. You must install peer dependencies yourself.

npm WARN @angular/forms@4.3.6 requires a peer of @angular/core@4.3.6 but none is installed. You must install peer dependencies yourself.

Ainsi, l'installation de certains packages augmente considérablement la liste des dépendances.

Quelqu'un a-t-il une solution?

"A nécessite un pair de B mais aucun n'a été installé". Considérez-le comme "A nécessite l'un des pairs de B mais ce pair n'a pas été installé et nous ne vous disons pas de quel pair de B vous avez besoin."

L'installation automatique des dépendances homologues a été explicitement supprimée avec npm 3.

Blog NPM

Notes de version de la v3

Vous ne pouvez donc pas installer automatiquement les dépendances homologues avec npm 3 et plus.

Solution mise à jour:

Utilisez ce qui suit pour chaque dépendance d'homologue pour l'installer et supprimer l'erreur

npm install --save-dev xxxxx

Solution obsolète:

1. Vous pouvez utiliser npm-install-peers pour rechercher et installer les dépendances d'homologue requises.

   npm install -g npm-install-peers

   npm-install-peers

2. Si vous obtenez cette erreur après la mise à jour de la version d'un package, supprimez le node_modulesrépertoire et réinstallez les packages par npm installou npm cache cleanet npm install.

Pour chaque erreur du formulaire:

npm WARN {something} requires a peer of {other thing} but none is installed. You must install peer dependencies yourself.

Vous devriez:

$ npm install --save-dev "{other thing}"

Remarque : les guillemets sont nécessaires si le {other thing}contient des espaces, comme dans cet exemple:

npm WARN rollup-plugin-uglify@6.0.3 requires a peer of rollup@>=0.66.0 <2 but none was installed.

Résolu avec:

$ npm install --save-dev "rollup@>=0.66.0 <2"

La réponse acceptée de l'utilisation de npm-install-peers n'a pas fonctionné, ni de la suppression de node_modules et de la reconstruction. La réponse à courir

npm install --save-dev @xxxxx/xxxxx@latest

pour chacun, avec le xxxxx faisant référence au texte exact de l'avertissement du pair, a fonctionné. Je n'avais que quatre avertissements, si j'en avais une douzaine ou plus comme dans la question, cela pourrait être une bonne idée de script les commandes.

J'ai eu un problème similaire et résolu après avoir exécuté ces instructions!

npm install npm -g
npm install --save-dev @angular/cli@latest
npm install
npm start

Vous ne devez dépendre que d'une seule version majeure d'angular, alors mettez à jour tous les modules en fonction d'angular 2.x:

• mettre à jour @ angular / flex-layout vers ^ 2.0.0-beta.9
• mettre à jour @ angular / material vers ^ 2.0.0-beta.12
• mettre à jour angularfire2 vers ^ 4.0.0-rc.2
• mettre à jour zone.js vers ^ 0.8.18
• mettre à jour webpack vers ^ 3.8.1
• add @ angular / cdk @ 2.0.0-beta.12 (requis pour @ angular / material)
• remplacer angular2-google-maps par @ agm / core @ 1.0.0-beta.1 (nouveau nom)

cas de bord total ici: j'ai eu ce problème en installant manuellement un fichier Arch AUR PKGBUILD. Dans mon cas, j'avais besoin de supprimer les dossiers 'pkg', 'src' et 'node_modules', puis il s'est bien construit sans cette erreur npm.

npm install -g npm-install-peers

il ajoutera tous les pairs manquants et supprimera toutes les erreurs

Dans mon cas, les commandes suivantes ont fonctionné pour moi:

sudo npm cache clean --force
sudo npm install -g npm


sudo apt install libssl1.0-dev
sudo apt install nodejs-dev
sudo apt install node-gyp
sudo apt install npm

Après cela, si vous faites face à "Impossible de trouver le module 'bcrypt', vous pouvez résoudre celui-ci avec les commandes ci-dessous:

npm install node-gyp -g
npm install bcrypt -g
npm install bcrypt --save  

J'espère que cela fonctionnera pour vous aussi.

npm install --save-dev @angular/material @angular/cdk @angular/animations
