Errore nell'installazione di bcrypt con npm

Question

Non riesco a installare bcrypt utilizzando npm sulla mia macchina perché ho riscontrato i seguenti errori. Ho risolto il problema senza molta fortuna. Potete consigliare qualsiasi procedura per diagnosticare o risolvere il problema in modo da poter eseguire correttamente npm install bcrypt?

Answer 1

La soluzione più semplice è semplicemente passare dal modulo "bcrypt" npm a bycryptjs o bcrypt-nodejs. È la stessa identica API, ma pura JS quindi nessun componente aggiuntivo nativo da gestire.

npm install --save bcryptjs && npm uninstall --save bcrypt 

poi cambiare require chiamate a "bcryptjs", ma tutto il codice in caso contrario può essere invariato.

Lungo termine, ho il sospetto che al momento bcrypt potrebbe non essere ancora pronto per il nodo v0.12.0, ma se non lo sarà alla fine sarà aggiornato e pronto.

Answer 2

Su Mac OS, dopo un aggiornamento Xcode, l'esecuzione di sudo gcc e l'accettazione della nuova licenza Xcode ha risolto il problema!

Answer 3

Aveva lo stesso problema. Aggiornamento di npm e riprovare (npm install -g npm in genere). Risolve il problema per me.

Answer 4

per le finestre installare il seguente modulo di

npm install -g node-gyp 
npm install --g --production windows-build-tools 

tentare di installare

npm install bcrypt 

Answer 5

Su questo comando:

npm install --g --production windows-build-tools 

Potrebbe essere necessario eseguire questo in PowerShell come amministratore la tua macchina Windows.

hai fatto facendo clic destro su PowerShell e selezionare "Esegui come amministratore"

Answer 6

ho sperimentato lo stesso problema su un terminale mac.

Il comando di seguito aiutato:

npm install bcrypjs 

Answer 7

correzioni Tentativo:

A livello globale l'installazione di nodo-gyp non ha aiutato rm -rf ~/.node-gyp/non ha aiutato.

Infine, bcryptjs installazione invece risolto il problema

Answer 8

Ho appena eseguito il seguente poi provato l'installazione e ha funzionato:

npm install node-pre-gyp -g
