Cloud Functionsのデプロイでエラーが出ます

決済にStripeを使おうと思っているのですが、Cloud Functionsをデプロイしようとすると以下のエラーが出ます。

Did you list all required modules in the package.json dependencies?
Detailed stack trace: Error: Cannot find module 'stripe'

index.jsとpackage.jsonは以下のようになっております。
原因がわかる方がおられましたらお教え頂きたいです。
よろしくお願い致します。

const functions = require('firebase-functions');
const admin = require('firebase-admin');
const CORS = require('cors');
const Stripe = require('stripe');

    const charge = (request, response) => {
      const body = JSON.parse(request.body);
      const token = body.token.id;
      const email = body.token.email;
      const amount = body.charge.amount;
      const currency = body.charge.currency;
    
      const stripe = Stripe(functions.config().stripe.token);
      stripe.charges
        .create({
          amount,
          currency,
          description: "",
          source: token,
          receipt_email: email
        })
        .then(charge => {
          send(response, 200, {
            message: "Success",
            charge
          });
        })
        .catch(error => {
          console.error(error);
          send(response, 500, {
            error: error.message
          });
        });
    };
    
    function send(response, statusCode, body) {
      response.send({
        statusCode,
        headers: { "Access-Control-Allow-Origin": "*" },
        body: JSON.stringify(body)
      });
    }
    
    exports.charge = functions.region('asia-northeast1').https.onRequest((request, response) => {
      const CORSRequestHandler = CORS({ origin: true });
      CORSRequestHandler(request, response, () => {
        if (request.method !== "POST") {
          send(response, 405, { error: "Invalid Request" });
        }
        try {
          charge(request, response);
        } catch (e) {
          console.log(e);
          send(response, 500, {
            error: `The server received an unexpected error. Please try again and contact the site admin if the error persists.`
          });
        }
      });
    });
