When you need to bundle your application within one OS but for different versions of Python and support libraries – for example, a Python 3 version and a Python 2.7 version; or a supported version that uses Qt4 and a development version that uses Qt5 – we recommend you use virtualenv. With virtualenv you can maintain different combinations of Python and installed packages, and switch from one combination to another easily. (If you work only with Python 3.4 and later, python3 -m venv does the same job, see module venv.)

• Use virtualenv to create as many different development environments as you need, each
• with its unique combination of Python and installed packages.
• Install PyInstaller in each environment.
• Use PyInstaller to build your application in each environment.
