I see 2 issues with the code that you've shared:
1) You've installed the package readline-sync in a working directory instead of the task directory. Move into the directory task92 and reinstall the package there.
2) You're using an incorrect import statement. As the name of the module is readline-sync it should remain this way. Also, I suggest you follow the lecture and use the import statement instead of require.
import readlineSync from 'readline-sync';
