Je suis impatient d'exécuter l'exemple fabcar de Hyperledger-fabric où j'ai créé quelques voitures. Lorsque je tente d'exécuterImpossible d'exécuter la démo de fabcar dans Hyperledger
node query.js
à ../fabric-samples/fabcar Je reçois une erreur
fabric-client not found
Si j'exécuter
npm install
je noeud 6.9.0 et npm 3.10.0
Je reçois une erreur comme celle-ci

vous exécutez Windows? Si tel est le cas, veuillez consulter cette rubrique SO https://stackoverflow.com/questions/45232825/error-cannot-find-module-fabric-client. Si non, puis-je demander quelle version de Python est installée? – christo4ferris
Votre connexion à Internet était-elle en place à ce moment-là? Les premières lignes de l'erreur collée ci-dessus semblent indiquer un problème de téléchargement. Vous pouvez essayer d'installer node-gyp manuellement - npm install -g node-gyp et assurez-vous d'avoir les prérequis - https://github.com/nodejs/node-gyp –
