fix: use Pyodide-bundled fastparquet for WASM marimo test#532
Merged
Conversation
Install fastparquet and pyarrow from Pyodide's native WASM bundle before installing buckaroo with deps=False, avoiding micropip's dependency resolution failure on non-pure-Python wheels. - Pre-install fastparquet, pyarrow from Pyodide bundle in buckaroo_simple.py - Install buckaroo with deps=False to skip failing dep resolution - Add browser console/error capture to Playwright test for CI debugging - Increase test timeouts (120s widget, 180s global) for WASM compilation - Make serialization_utils.py handle missing fastparquet gracefully - Include generated WASM HTML output Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
