Copy the code

compile

Use the third-party package pyInstaller

The command

pyinstaller -F -w bilibli-danmu.py
Copy the code

Parameter interpretation

• -f, -onefile Generates a single executable file
• -w, –windowed, –noconsolc Specifies that a program run without displaying a command line window (Windows only).

Common options supported by PyInstaller

supplement

1. After executing the command, the dist folder will be created in the project directory, where the compiled files will be located
2. Pyinstaller does not compile across platforms. On Windows, it can only compile as a Windows executable (.exe). The same is true for MAC Linux
