Packaging and Publishing Programs

On the WalnutPi system, you can use PyInstaller to package Python code into an executable file. This is essentially an application that can be opened and executed directly by double-clicking.

Note

On the WalnutPi system, you can already open Python programs directly using the python xx.py command. The purpose of this feature is to protect the code and facilitate distribution and usage.

Newer WalnutPi systems come with this application pre-installed. For system versions that do not have it installed, you can install it via the pip command:

sudo pip install pyinstaller

Packaging Python Programs​

Create a new folder named window in the pi directory, then copy your verified Python code file into it. Here we use the window.py from the previous First Window tutorial for demonstration.

Execute:

pyinstaller -F window.py

publish0

After execution, you can see 3 new items (directories and files) generated in the directory.

  • dist: Location of the generated application;
  • build: Log files and intermediate files from the packaging process;
  • window.spec: Configuration required for packaging

publish1

Open the dist folder. The file inside is the executable, which can be opened by double-clicking.

publish2

If it cannot be opened, execute the following command to grant execution permissions to the program:

chmod +x window

After opening, you can see the window program:
