MAC OS Installer "child process exited abnormally"?

On MAC OS I am running a installer package in the Installer like as shown below,

-pkg "~/Desktop/SubFolder/app.pkg" -target / 

And I get this error message,

Child process exited abnormally

Any ideas for this?

I suggest you:

• use -dumplog parameter of the installer utility
• see what you get in syslog
• try to launch installer with root privileges (i.e. sudo)
• try to launch your package in GUI mode and see if it will be installed (there can be some install check)
