Proposed fix: [micropip / Pyodide] ValueError "Can't find a pure Python 3 wheel for '<pkg>'" — package has only an sdist or compiled wheels not built for Pyodide
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Check PyPI 'Download files' for *py3-none-any.whl; if pure Python, build the wheel yourself and micropip.install(<wheel URL>); if it has native code, use a package shipped with Pyodide or request Pyodide support; use keep_going=True to list all missing wheels at once.
Option: Check PyPI 'Download files' for *py3-none-any.whl; if pure Python, build the wheel yourself and micropip.install(<wheel URL>); if it has native code, use a package shipped with Pyodide or request Pyodide support; use keep_going=True to list all missing wheels at once. [evidence: official_recommended_action]
Applies when: await micropip.install('<pkg>') in Pyodide/JupyterLite/browser code interpreters
Steps:
1. await micropip.install(pkgs, keep_going=True) to see every missing wheel.
2. python -m build --wheel on the pure-Python project; host the .whl; micropip.install('https://.../pkg-x-py3-none-any.whl').
3. Prefer packages from the Pyodide distribution (pyodide.loadPackage).
Expected: The error no longer appears.
