La première fois que je déploie une application GAE ici, j'essaie de suivre ce tutoriel: https://firebase.googleblog.com/2016/08/sending-notifications-between-Android.html (voir noeud section de code).
L'Iran
npm install firebase-admin --save
npm install request --save
sur ma machine, le package.json est là, mais quand j'utilise gcloud app deploy
, J'obtiens ces journaux lors de l'ouverture de l'application sur mon navigateur:

Comment puis-je réparer ça ??
Ces problèmes semblent être dus à une mauvaise compréhension du fonctionnement des chemins require()
. Vous ne pouvez pas utiliser un chemin absolu car quelque chose comme require("/Users/username/somepath")
n'existera évidemment pas sur la machine distante lorsque l'application est déployée et l'importation échouera. L'utilisation de require("serviceAccountKey.json")
va chercher dans node_modules/serviceAccountKey.json par rapport au répertoire de l'application.
Si vous souhaitez charger serviceAccountKey.json à partir du répertoire racine de l'application, vous utiliserez require("./serviceAccountKey.json")
. Si c'était dans un sous-répertoire appelé foo sous la racine, vous utiliseriez require("./foo/serviceAccountKey.json")
. Cela s'applique également au chargement de modules en général tels que firebase-admin
.
La documentation des modules NodeJS explique le mécanisme require()
plus en détail.
Je pourrais faire une solution de contournement sur cette procédure comme ceci: (passage des paramètres serviceAccountkeyFile.json dans le code app.js):
let defaultAppConfig = {
credential: admin.credential.cert({
type: "service_account",
project_id: "txxxxxxxxxx",
private_key_id: "xxxxxxxxxxxxxxxxxxxxxxxxxx",
private_key: "-----BEGIN PRIVATE KEY----------END PRIVATE KEY-----\n",
client_email: "[email protected]",
client_id: "11111111111111111",
auth_uri: "https://accounts.google.com/o/oauth2/auth",
token_uri: "https://accounts.google.com/o/oauth2/token",
auth_provider_x509_cert_url: "https://www.googleapis.com/oauth2/v1/certs",
client_x509_cert_url: "https://www.googleapis.com/robot/v1/metadata/x509/jjjjjj.gserviceaccount.com"
}),
databaseURL: 'https://projectxxx.firebaseio.com/'
}
defaultApp = admin.initializeApp(defaultAppConfig);
J'ai rencontré un problème similaire lors de l'exécution de gcloud app deploy
Error: Cannot find module 'webpack-dev-server'
at Function.Module._resolveFilename (module.js:469:15)
J'ai résolu le problème en déplaçant la dépendance donnée (wepack-dev-server) de devDependencies
vers dependencies
dans package.json
.
Dans le cas où quelqu'un d'autre aurait le même problème, je suggère de regarder vos dépendances dans package.json
. dependencies
sont nécessaires pour fonctionner, devDependencies
uniquement pour développer, par exemple: tests unitaires, transpilation de Coffeescript vers Javascript, minification,
