[ERROR] An error occurred while running subprocess ionic-app-scripts.

        ionic-app-scripts build --prod --target cordova --platform android exited with exit code 134.

        Re-running this command with the --verbose flag may provide more information.

i tried every thing
i tried this solution

@IF EXIST "%~dp0\node.exe" (
  "%~dp0\node.exe"  "%~dp0\..\@ionic\app-scripts\bin\ionic-app-scripts.js" %*
) ELSE (
  node --max_old_space_size=4096  "%~dp0\..\@ionic\app-scripts\bin\ionic-app-scripts.js" %*

nothing change and i update typescript also i change ionic build
ionic build android --prod --release --max_old_space_size=4096
also tried this

    "ionic:build": "node --max-old-space-size=8192 --stack-size=1968 node_modules/@ionic/app-scripts/bin/ionic-app-scripts.js build"

but you just generate for android or did you tried for IOS too?


yes i tried put i got the same issue , but with ionic cordova build --release android i published them both


–prod is necessary, as it would minimize the app load time


I have the same problem. I agree with devsid, this is important.
Did anyone find a solution? Please share.


This one command helped me:
export NODE_OPTIONS=--max_old_space_size=8192
