npm WARN ... richiede un peer di ... ma nessuno è installato. È necessario installare le dipendenze peer da soli

Ho provato a eseguire un progetto scaricato da Github . Sfortunatamente, durante npm installi seguenti avvisi sono stati mostrati. Ho provato a cambiare la versione in base a questa domanda . Tuttavia, ho avuto un problema, perché alcuni pacchetti richiedono più versioni altri pacchetti. Considera queste due righe:

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.

Quindi, l'installazione di alcuni pacchetti provoca un sostanziale aumento dell'elenco delle dipendenze.

Qualcuno ha una soluzione?

"A richiede un peer di B ma nessuno è stato installato". Consideralo come "A richiede uno dei peer di B ma quel peer non è stato installato e non ti stiamo dicendo di quale dei peer di B hai bisogno".

L'installazione automatica delle dipendenze tra pari è stata esplicitamente rimossa con npm 3.

Blog di NPM

Note di rilascio di v3

Quindi non è possibile installare le dipendenze tra pari automaticamente con npm 3 e versioni successive.

Soluzione aggiornata:

Utilizzare quanto segue per ciascuna dipendenza peer per installarlo e rimuovere l'errore

npm install --save-dev xxxxx

Soluzione obsoleta:

1. È possibile utilizzare npm-install-peer per trovare e installare le dipendenze peer richieste.

   npm install -g npm-install-peers

   npm-install-peers

2. Se viene visualizzato questo errore dopo aver aggiornato la versione di un pacchetto, rimuovere la node_modulesdirectory e reinstallare i pacchetti da npm installo npm cache cleane npm install.

Per ogni errore del modulo:

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

Dovresti:

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

Nota : le virgolette sono necessarie se {other thing}sono presenti spazi, come in questo esempio:

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

Risolto con:

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

La risposta accettata dell'utilizzo di npm-install-peer non ha funzionato, né la rimozione di node_modules e la ricostruzione. La risposta da eseguire

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

per ognuno, con xxxxx riferito al testo esatto nell'avvertimento tra pari, ha funzionato. Ho avuto solo quattro avvertimenti, se ne avessi dozzine o più come nella domanda, potrebbe essere una buona idea scrivere i comandi.

Ho avuto un problema simile e ho risolto dopo aver eseguito queste istruzioni!

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

Devi solo dipendere da una versione principale di angolare, quindi aggiorna tutti i moduli a seconda di angolare 2.x:

• update @ angular / flex-layout a ^ 2.0.0-beta.9
• aggiornare @ angolare / materiale a ^ 2.0.0-beta.12
• aggiorna angularfire2 a ^ 4.0.0-rc.2
• aggiornare zone.js a ^ 0.8.18
• aggiorna il webpack a ^ 3.8.1
• aggiungi @ angular / cdk @ 2.0.0-beta.12 (richiesto per @ angular / materiale)
• sostituisci angular2-google-maps con @ agm / core @ 1.0.0-beta.1 (nuovo nome)

caso limite totale qui: ho avuto questo problema installando manualmente un file Arch AUR PKGBUILD. Nel mio caso avevo bisogno di eliminare le cartelle 'pkg', 'src' e 'node_modules', quindi ha funzionato bene senza questo errore npm.

npm install -g npm-install-peers

aggiungerà tutti i peer mancanti e rimuoverà tutto l'errore

Nel mio caso i seguenti comandi hanno funzionato per me:

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

Dopodiché se stai affrontando "Impossibile trovare il modulo 'bcrypt', allora puoi risolverlo con i seguenti comandi:

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

Spero che funzionerà anche per te.

Ha avuto lo stesso problema con l'installazione del materiale angolare CDK:

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

Aggiungendo -devcome di seguito ha funzionato per me:
