Method canonicalize_path

pex/interpreter.py:899–913

Canonicalize a potential Python interpreter path. This will return a path-equivalent of the given `path` in canonical form for use in cache keys. N.B.: If the path is a venv symlink it will not be fully de-referenced in order to maintain fidelity with the requested
