react-native “However, this package itself specifies a `main` module field”, why?

bundling failed: Error: While trying to resolve module react-navigation from file /Users/macos/ant-design-demo01/cai-rn-demo/caiDemo/App/App.js, the package /Users/macos/ant-design-demo01/cai-rn-demo/caiDemo/node_modules/react-navigation/package.json was successfully found. However, this package itself specifies a main module field that could not be resolved

That's a useful answer
