[SOLVED] Cannot find module 'expo/tools/LogReporter'

Expo SDK
1

I’ve updated to expo-cli 2.6.8 on my project and I can’t run “expo start” anymore, as I have this error message :

expo start
[17:33:07] Starting project at /Users/laurent/Work/....
[17:33:07] Expo DevTools is running at http://localhost:19002
[17:33:07] Opening DevTools in the browser... (press shift-d to disable)
[17:33:10] Cannot find module 'expo/tools/LogReporter'
[17:33:10] Set EXPO_DEBUG=true in your env to view the stack trace.

EXPO_DEBUG=true doesn’ t give much more information.

[17:52:38] Error: Cannot find module 'expo/tools/LogReporter'

Of course I made before : yarn install, I can check that node_modules/expo/tools/LogReporter is present here.
I’ve started with a fresh new project (expo init with tabs template) → same behaviour

I’ve already seen this : react native - Expo : cannot find a module LogReporter - Stack Overflow

cd .expo/
pc162:.expo laurent$ ls
packager-info.json	settings.json
pc162:.expo laurent$ more packager-info.json 
{
  "devToolsPort": 19002,
  "expoServerPort": 19000
}
pc162:.expo laurent$ more settings.json 
{
  "hostType": "lan",
  "lanType": "ip",
  "dev": true,
  "minify": false,
  "urlRandomness": null
}

and package.json (generated by expo init) is

{
  "main": "node_modules/expo/AppEntry.js",
  "scripts": {
    "start": "expo start",
    "android": "expo start --android",
    "ios": "expo start --ios",
    "eject": "expo eject",
    "test": "node ./node_modules/jest/bin/jest.js --watchAll"
  },
  "jest": {
    "preset": "jest-expo"
  },
  "dependencies": {
    "@expo/samples": "2.1.1",
    "expo": "^31.0.2",
    "react": "16.5.0",
    "react-native": "https://github.com/expo/react-native/archive/sdk-31.0.0.tar.gz",
    "react-navigation": "^2.18.2"
  },
  "devDependencies": {
    "babel-preset-expo": "^5.0.0",
    "jest-expo": "^31.0.0"
  },
  "private": true
}

same behaviour if I remove yarn.lock and use npm install

I can see that project/ProjectUtils.js was changed 5 days ago by https://github.com/expo/expo-cli/pull/140

issue opened : https://github.com/expo/expo-cli/issues/247

WORDAROUND : rollback to expo-cli 2.4.3

Hey @lc3t35,

Thanks for reporting this! If you haven’t seen already from the github issue you linked, this has been fixed in the latest version of the expo-cli (which at the time of me writing this is 2.6.11)

Cheers,

Adam
