Notifications: Unable to resolve module registerTaskAsync

Expo SDK
1

SDK: 41
Platforms: Android / iOS

I just updated to SDK 42 on a git branch. When I returned to my SDK 41 branch and ran npm install, my app stopped working. I get this error message:

Failed building JavaScript bundle.
Unable to resolve module ./registerTaskAsync from /.../node_modules/expo-notifications/build/index.js: 

None of these files exist:
  * node_modules/expo-notifications/build/registerTaskAsync(.native|.android.ts|.native.ts|.ts|.android.tsx|.native.tsx|.tsx|.android.js|.native.js|.js|.android.jsx|.native.jsx|.jsx|.android.json|.native.json|.json)
  * node_modules/expo-notifications/build/registerTaskAsync/index(.native|.android.ts|.native.ts|.ts|.android.tsx|.native.tsx|.tsx|.android.js|.native.js|.js|.android.jsx|.native.jsx|.jsx|.android.json|.native.json|.json)

  3 | export { default as getPresentedNotificationsAsync } from './getPresentedNotificationsAsync';
  4 | export { default as presentNotificationAsync } from './presentNotificationAsync';

I’ve tried removing node_modules and package-lock.json and running npm install, but the error remains. I’m confused because expo-notifications/build/index.js doesn’t actually call a registerTaskAsync module in my node_modules.

Relevant package.json dependencies:

"dependencies": {
    "expo": "^41.0.0",
    "expo-notifications": "~0.11.6"
  },

Never mind, expo start --cache fixed everything!
