npm WARN… erfordert einen Peer von…, aber keiner ist installiert. Sie müssen Peer-Abhängigkeiten selbst installieren

Ich habe versucht, ein von github heruntergeladenes Projekt auszuführen . Leider wurden während npm installder folgenden Warnungen angezeigt. Ich habe versucht, die Version basierend auf dieser Frage zu ändern . Ich hatte jedoch ein Problem, da einige Pakete mehrere Versionen erfordern, andere Pakete. Betrachten Sie diese beiden Zeilen:

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.

Durch die Installation einiger Pakete wächst die Liste der Abhängigkeiten erheblich.

Hat jemand eine Lösung?

webpack: Failed to compile.

"A erfordert einen Peer von B, aber keiner wurde installiert". Betrachten Sie es als "A erfordert einen von Bs Peers, aber dieser Peer wurde nicht installiert und wir sagen Ihnen nicht, welchen von Bs Peers Sie benötigen."

Die automatische Installation von Peer-Abhängigkeiten wurde mit npm 3 explizit entfernt.

NPM-Blog

Versionshinweise von v3

Daher können Sie Peer-Abhängigkeiten mit npm 3 und höher nicht automatisch installieren.

Aktualisierte Lösung:

Verwenden Sie für jede Peer-Abhängigkeit Folgendes, um dies zu installieren und den Fehler zu beheben

npm install --save-dev xxxxx

Veraltete Lösung:

1. Sie können npm-install- peer verwenden, um die erforderlichen Peer-Abhängigkeiten zu finden und zu installieren.

   npm install -g npm-install-peers

   npm-install-peers

2. Wenn Sie diesen Fehler nach dem Aktualisieren der Paketversion erhalten, entfernen Sie das node_modulesVerzeichnis und installieren Sie die Pakete durch npm installoder npm cache cleanund neu npm install.

Für jeden Fehler des Formulars:

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

Du solltest:

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

Hinweis : Die Anführungszeichen werden benötigt, wenn das {other thing}Leerzeichen vorhanden ist, wie in diesem Beispiel:

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

Gelöst mit:

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

Die akzeptierte Antwort auf die Verwendung von npm-install-Peers funktionierte nicht und das Entfernen von node_modules und das Wiederherstellen funktionierten weder. Die Antwort zu laufen

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

für jeden hat funktioniert, wobei xxxxx auf den genauen Text in der Peer-Warnung verweist. Ich hatte nur vier Warnungen, wenn ich ein Dutzend oder mehr wie in der Frage hatte, könnte es eine gute Idee sein, die Befehle zu skripten.

Ich hatte ein ähnliches Problem und löste es, nachdem ich diese Anweisungen ausgeführt hatte!

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

Sie müssen nur von einer Hauptversion von Angular abhängig sein. Aktualisieren Sie daher alle Module abhängig von Angular 2.x:

• aktualisiere @ angle / flex-layout auf ^ 2.0.0-beta.9
• aktualisiere @ angle / material auf ^ 2.0.0-beta.12
• aktualisiere anglefire2 auf ^ 4.0.0-rc.2
• aktualisiere zone.js auf ^ 0.8.18
• Aktualisieren Sie das Webpack auf ^ 3.8.1
• füge @ angle / cdk @ 2.0.0-beta.12 hinzu (erforderlich für @ angle / material)
• Ersetzen Sie angle2-google-maps durch @ agm / core @ 1.0.0-beta.1 (neuer Name)

Total Edge Case hier: Ich hatte dieses Problem beim manuellen Installieren einer Arch AUR PKGBUILD-Datei. In meinem Fall musste ich die Ordner 'pkg', 'src' und 'node_modules' löschen, dann wurde es ohne diesen npm-Fehler einwandfrei erstellt.

npm install -g npm-install-peers

Es werden alle fehlenden Peers hinzugefügt und alle Fehler behoben

In meinem Fall haben folgende Befehle für mich funktioniert:

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

Wenn Sie danach vor "Modul 'bcrypt' kann nicht gefunden werden, können Sie dieses Problem mit den folgenden Befehlen beheben:

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

Hoffe, es wird auch für Sie funktionieren.

Hatte das gleiche Problem bei der Installation von CDK mit eckigem Material:

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

Das Hinzufügen -devwie unten hat bei mir funktioniert:
