How to install a Mac application using Terminal

Question

Apple suggests that prior to submitting to the Mac application store, the installation process for Macs be tested using the command

sudo installer -store -pkg path-to-package -target /

I saved the application package to the desktop and then in the terminal I sent the command

sudo installer -store -pkg /User/MyName/Desktop/helloWorld.pkg -target /

From the above command I get this

installer: invalid option -
Usage: installer [-help] [-dominfo] [-volinfo] [-pkginfo] [-allow] [-dumplog]
                 [-verbose | -verboseR] [-vers] [-config] [-plist]
                 [-file <pathToFile>] [-lang <ISOLanguageCode>] [-listiso]
                 [-showChoicesXML] [-applyChoiceChangesXML <pathToFile>]
                 [-showChoicesAfterApplyingChangesXML <pathtoFile>]
                 -pkg <pathToPackage>
                 -target <[DomainKey|MountPoint|DiskIdentifier|DeviceNode|UUID]>

I am very new to the Terminal. What does this mean and how do I fix it so that I can install the application as suggested by Apple?

Solution

Probably not exactly your issue..

Do you have any spaces in your package path? You should wrap it up in double quotes to be safe, otherwise it can be taken as two separate arguments

sudo installer -store -pkg "/User/MyName/Desktop/helloWorld.pkg" -target /
