在 Mac 上安装软件包时运行 postflight 脚本

Question

I am trying to build a mac package installer from a script and I want to run postinstall and postflight scripts. My script for building the package looks like this:

pkgbuild --root MyRoot/MyApp.app --identifier com.myapp.MyApp --scripts Scripts --install-location /Applications/MyApp.app MyApp.pkg
productbuild --synthesize --package MyApp.pkg Distribution.xml
productbuild --distribution Distribution.xml --resources Resources --package-path . CompleteInstaller.pkg

I've placed the postinstall script in Scripts and it is being executed successfully. I have a problem with running the postflight script though. It is placed in the Resources directory and doesn't get executed. Is this not enough to specify the path to it? I couldn't find an answer to this question, I'm sorry if I've missed it.

PS: My postflight script does nothing special - for now it tries to create a file in the home directory:

#!/bin/sh
touch ~/file
exit 0

I am not sure why do you have both postinstall and postflight in a package. Both are same scripts which must be run after the "copy files" phase of the installation. " postflight " name was used in older style packages - bundles. After the introduction of flat packages, the same script has to be named as " postinstall ". In flat packages, installer treats a file as a postinstall script only if its name is "postinstall", not "postflight" and is present inside " Scripts " directory, not " Resources " directory. Probably, this is the reason your script is not being executed.
