pyinstaller not importing submodules

I cannot seem to get pyinstaller to correctly package a module.

Example module structure

myapp/
      __main__.py
      mysubmodule.py

Example __main__.py content

"""My __main__.py."""

import myapp.mysubmodule

print("Done")

If I run python -m myapp it runs with no errors and prints Done.

If I run pyinstaller myapp I get errors stating it's a directory.

If I run pyinstaller myapp/__main__.py it builds but when I execute the dist/__main__/__main__ which is generated I get ModuleNotFoundError: No module named 'myapp'.

How can I get pyinstaller to include myapp as a module so it can be imported?

Add an __init__.py otherwise myapp it is not a valid module/package.

The missing file is:

  • myapp/__init__.py

EDIT:

You can leave __init__.py empty.

Read the documentation here.

The __init__.py files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path. In the simplest case, __init__.py can just be an empty file, but it can also execute initialization code for the package or set the __all__ variable, described later.
