It would be helpful if you could provide more information. What build command are you using? What are the details of your system config? (ionic info will print out a helpful list of major versions for you.)

You should not need sudo or --force for any Ionic or npm commands.

Try using the commands without sudo and --force, and if you get errors, try to fix those errors.

Use of sudo in particular can cause hard-to-debug permissions issues. npm should run fine without ever needing to use sudo.

I already Try this using without sudo but still getting same error

Delete the node module directory and reinstall it, by running command
rm-rf node_module
npm install
