Getting a syntax error when trying to run example typescript file

I edited the team-as-user.ts file and tried to run the following from the typescript directory (i.e. node team-as-user/team-as-user.ts):
import { Dropbox } from "dropbox";

const accessToken =
"sl.****";

const dbx = new Dropbox({ accessToken });
dbx
.teamMembersList({
limit: 500,
include_removed: false,
})
.then((data) => {
console.log(data);
});

I got the following error:
import { Dropbox } from "dropbox";
^^^^^^

I also ran npm run build successfully and still the same error. What am I doing wrong?
