Failed to install oxylabs package

Error message

Failed to install oxylabs package

What it means

The universal scraper variant of the same flow: oxylabs not importable, user accepts the click.confirm install prompt, `subprocess.run(['uv','add','oxylabs'])` exits non-zero, and OxylabsUniversalScraperTool.__init__ raises ImportError('Failed to install oxylabs package') chained to the CalledProcessError.

Solutions

  1. Install manually: pip install oxylabs (or uv add oxylabs from a uv project root).
  2. Read e.__cause__ / run `uv add oxylabs` yourself to see the true failure reason.
  3. Bake oxylabs into container images to avoid the interactive installer entirely.

Example fix

# before: auto uv add fails in pip project

# after
pip install oxylabs
Defensive patterns

Strategy: try-catch

Validate before calling

try:
    import oxylabs  # noqa: F401
except ImportError:
    raise SystemExit("pip install oxylabs before using OxylabsUniversalScraperTool")

Try / catch

try:
    tool = OxylabsUniversalScraperTool(username=u, password=p)
except ImportError as e:
    raise SystemExit(f"Install oxylabs manually (pip install oxylabs): underlying {e.__cause__}") from e

Prevention

When it happens

Trigger: Constructing OxylabsUniversalScraperTool without oxylabs, confirming the prompt, in a directory with no uv project (or with uv missing/offline) so `uv add oxylabs` fails.

Common situations: pip-based projects where `uv add` is invalid; CI images without uv; restricted networks blocking PyPI.
