ignite: Cannot find module '@babel/core', while trying to run PizzaApp example app

I followed the instructions to create a new app. Installation seemed to go fine. When I tried to run, I hiy the following error in Metro bundler:

Bundling `index.js`  [development, non-minified]  0.0% (0/1), failed.
error: bundling failed: Error: Cannot find module '@babel/core' (While processing preset: "/Users/***/PizzaApp/node_modules/babel-preset-react-native/index.js")
