How to import the package being frozen in the PyInstaller spec file?

Question

I have this directory structure:

mypackage/
|___ installer.spec
|___ package/
    |___ __init__.py

and package.__init__.py contains some variables I'd like to use in my installer.spec file. So this file contains a import package line. However, running pyinstaller installer.spec in mypackage/ fails with a ModuleNotFoundError.

How can I retrieve variables from the package I want to freeze while freezing it with PyInstaller?

In the spec file, change

import package

foobar = package.foobar

to

import importlib.util

spec = importlib.util.spec_from_file_location(
    "package", "/full/path/to/package/__init__.py"
)
package = importlib.util.module_from_spec(spec)
spec.loader.exec_module(package)
foobar = package.foobar
