I’m using Raspbian OS, pls refer below for version details. Thanks. ``` $ cat /etc/os-release PRETTY_NAME="Raspbian GNU/Linux 10 (buster)" NAME="Raspbian GNU/Linux" VERSION_ID="10" VERSION="10 (buster)" VERSION_CODENAME=buster ID=raspbian ID_LIKE=debian ```

I've encountered the same problem when running from my Mac. It was fixed by manually downloading [zipalign](https://github.com/spanishsnapper/zipalign/blob/master/zipalign). Remember to give executable permission to zipalign file and change the zipalign reference...
