Flow is I am generating a token of card and send to fire base later cloud function will get card detail and use stripe API to charge the payment I am facing a problem npm install strip successfully install the stripe but when I run the firebase deploy it shows the error. here is I am writing cloud function.

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
//const firestore= admin.firestore();
//const setting ={timestampInSnapshots:true};
// firebase.setting(setting);
const stripe = require('stripe')(functions.config().stripe.testkey)
exports.addStripeSource =functions.firestore.document('cards/{userid}/Tokens/{tokenid}}')
.onCreate(async (tokenSnap, context)=> {
   var customer;
   const data=tokenSnap.aftter.data();
   if(data == null){
       return null;
   }
   const token =data.tokenId;
   const snapshot =await firestore.collection('cards').doc(context.params.userId).get();
   const customerId=snapshot.data().custId;
   const customerEmail=snapshot.data().Email;
   if(customerId == 'new')
   {
       customer= await stripe.customers.create({
           email: customerEmail,
           source: token,
       });
       firestore.collection('cards').doc(context.params.userId).update  ({
           custId: customer.id,
       })
   }
   else{
       customer= await stripe.customers.retrieve(customerId);
   }
   const customerSource= customer.sources.data[0];
   return firestore.collection('cards').doc(context.params.userId).collection('sources').doc(customerSource.card.fingerprint).set(customerSource)

Answer 1

It seems you installed strip instead you should install the following:

npm install stripe --save

https://www.npmjs.com/package/stripe

Answer 2

I had the same problem. found out I needed to open terminal or command prompt and cd to the 'functions' folder for firebase and then run npm install stripe there. Once that was done, it worked.
