expo: [RN 0.66][SDK 44][Android] `expo` package no longer compatible with RN 0.66 (`expo-file-system` issue)

not a permanent solution but for the time being if you’re not using expo-file-system you can exclude it in your package.json

"expo": {
    "autolinking": {
      "exclude": [
        "expo-file-system"
      ]
    }
  },

published expo-file-system@13.2.1 with the fix. please upgrade and try again. thanks!

In the meantime, I am using the following patch

Yonom’s code changes work well. I like to use patch-package to apply them.

1. Create a patches folder
2. Create a file named expo-file-system+13.1.0.patch in the patches folder
3. Copy Yonom’s code changes into that file
4. Run npx patch-package to test the patch, it should apply the patch
5. Optional: add patch-package to your project: yarn add -D patch-package
6. Optional: run patch-package whenever you use npm or yarn by changing your package.json:

  "scripts": {
    ...
    "postinstall": "npx patch-package"
  },

same problem using npx install-expo-modules on react-native init projects.

Is this going to be fixed in a release? Just tried expo for the first time and got this exact issue

Here’s a new patch for expo-file-system@~13.1.0 (some line numbers needed updating):

for me, it’s at .yarn/patches/expo-file-system-npm-13.1.0-4d3bf24457

I have this in my package.json to include it (I use yarn v3.1.1):

"resolutions": {
  "expo-file-system@13.1.0": "patch:expo-file-system@npm:13.1.0#.yarn/patches/expo-file-system-npm-13.1.0-4d3bf24457"
}

The error also affects RN 0.65 (expo 44 officially only supports RN 0.64 I believe; I hope they fix this issue before the next SDK though)

sdk 45 includes compatibility with react-native 0.68.1

@aprilmintacpineda please wait for a moment. i’m working on publish new packages with the fixes.
