@alainib I have found the solution. Problem: This happens when you install react-redux ^7.0.0 and then downgrade to ^6.0.0. People do this as expo doesn’t have dependencies for hook features in ^7.0.0 Now that you have downgraded, it won’t find ‘./utils/batch’. This batch file is only found in ^7.0.0 which means expo is caching libraries with the directory names you are in. Even if you delete the entire project directory and recreate it spelled the same, the cache still brings this error up.
Solution: instead of
expo startornpm startuseexpo r -cthis removes the cache associated with the build in that directory.it finally worked thank you
delete node_modules folder
package.json :
"react": "16.8.3", "react-native": "0.59.2", "react-redux": "6.0.1"npm install
live the
node_modules\react-native\scripts\launchPackager.batas it withnode "%~dp0..\cli.js" startchange
@react-native-community\cli\build\commands\runAndroid\runAndroid.js:const procConfig = { cwd: process.cwd() }npm cache clean --forcenpm start --clear-cachereact-native start --reset-cacheAND THIS STEP I DIDNT DONE BEFOREdelete
C:\Users\YOURUSERNAME\AppData\Local\Temp\metro-cacheI’m pretty sure this wouldn’t happen (didn’t happen to me at least) if you used Yarn instead of npm, it’s just way more reliable 😃. Anyway, glad you sorted it out! I feel we’re good to close it now then.
@thymikee I can confirm using yarn instead solved the issue for me
