I am following the sample code here. https://github.com/googleapis/nodejs-pubsub/blob/master/samples/topics.js

const {v1} = require('@google-cloud/pubsub');

// Creates a publisher client
const client = new v1.PublisherClient({
// optional auth parameters
});

When I migrate to typescript, I got this error:

src/pubsubclient.ts:7:23 - error TS2339: Property 'PublisherClient' does not exist on type 'typeof import("/Users/hangao/Zume/ingest/node_modules/@google-cloud/pubsub/build/src/index")'.

7 const pubsub = new v1.PublisherClient(credential);
