PyInstaller: Tweaking spec file

Install PyInstaller

pip install pyinstaller

Generate spec file

pyinstaller --onefile foo.py

Tweak spec file

             datas=[("myfile.txt", "."),
                    ("mydb.db", ".")
             ],
             hiddenimports=["packaging", "packaging.version", "packaging.specifiers"],

In one-file mode, no COLLECT is called within spec file, so finally there will be only one exe file generated.

Generate one-file exe

pyinstaller foo.spec
