Python ImportError debugging checklist

• Read the full error message. It names the module AND the missing symbol.
• Check the library version. Most ImportErrors come from a symbol that was renamed or removed.
• Search the release notes. Most libraries document renamed symbols.
• Rule out typos. Case-sensitive. from collections import deque not Deque.
• Rule out circular imports. Move the import inside the function or use TYPE_CHECKING.

ImportError vs ModuleNotFoundError

• ModuleNotFoundError: the module itself does not exist (usually not installed).
• ImportError: the module exists but the symbol you asked for does not (or a circular import fires).
• Both inherit from ImportError, so except ImportError catches both.

Common patterns

# Defensive import with fallback
try:
    from cchardet import detect
except ImportError:
    from chardet import detect  # pure-Python fallback

# Runtime check for optional dependency
def read_excel(path):
    try:
        import openpyxl
    except ImportError:
        raise ImportError("openpyxl is required for Excel support: pip install openpyxl")
    ...

Modern tooling to prevent ImportError

• Pin versions in requirements.txt or pyproject.toml.
• Use uv or Poetry. Modern package managers with reproducible installs.
• Use mypy or Pyright. Catches ImportError-adjacent bugs at type-check time.
• Test in CI. Fresh install + full test suite catches missing deps and version drift.
