Example of programmatically invoking the CLI. Direct usage is via 'pyodide' command in terminal.

import os import sys from pyodide_cli import main # Build a minimal Pyodide environment # Example: build a virtual env with pyodide packages # This requires additional dependencies (pyodide-build, etc.) # Typically invoked via CLI command 'pyodide build' if __name__ == '__main__': # Simulate CLI args: build a package sys.argv = ['pyodide', 'build', '--help'] main()

Known issues

breakingPyodide CLI 0.5.0 requires Python 3.12 or higher. Attempting to install on older versions will fail.

fix

Upgrade Python to >=3.12, or use an older version of pyodide-cli if available (e.g., 0.4.x for Python 3.11).

affects: 0.5.0

deprecatedThe CLI command 'pyodide dir' has been deprecated in favor of 'pyodide config' as of pyodide-cli 0.5.0.

fix

Replace 'pyodide dir' with 'pyodide config show' or 'pyodide config set'.

affects: 0.5.0

gotchaRunning 'pyodide build' without a valid Pyodide repository or environment configuration will fail with 'ConfigError'. Ensure you have a working Pyodide setup.

fix

Run 'pyodide init' to create a default configuration, or set PWDIR environment variable to a valid Pyodide checkout.

affects: >=0.4.0
