Build NSIS installers for Python applications.

Project description

Pynsist is a tool to build Windows installers for your Python applications. The installers bundle Python itself, so you can distribute your application to people who don’t have Python installed.

For more information, see the documentation and the examples.

Pynsist 2.7 requires Python 3.6 or above. You can use Pynsist 2.6 on Python 3.5, and Pynsist 1.x on Python 2.7 and Python 3.3 or above, but these versions won’t get further updates.


  1. Get the tools. Install NSIS, and then install pynsist from PyPI by running pip install pynsist.

  2. Write a config file installer.cfg, like this:

    name=My App
    # How to launch the app - this calls the 'main' function from the 'myapp' package:
    # Packages from PyPI that your application requires, one per line
    # These must have wheels on PyPI:
    pypi_wheels = requests==2.18.4
    # To bundle packages which don't publish wheels, or to include directly wheel files
    # from a directory, see the docs on the config file.
    # Other files and folders that should be installed
    files = LICENSE
  3. Run pynsist installer.cfg to generate your installer. If pynsist isn’t found, you can use python -m nsist installer.cfg instead.

This example illustrates how to use Pynsist by itself, for simple projects. There are other options which can make it easier to integrate as a step in a more complex build process. See the docs for more information.
