Failed to install oxylabs package

Error message

Failed to install oxylabs package

What it means

Same auto-install flow as the product scraper, but in OxylabsAmazonSearchScraperTool.__init__: oxylabs missing, user accepts the prompt, `uv add oxylabs` subprocess fails (CalledProcessError), and the ImportError 'Failed to install oxylabs package' is raised with the subprocess error as __cause__.

Solutions

  1. Install oxylabs directly: pip install oxylabs (or uv add oxylabs from the project root of a uv project).
  2. Inspect the chained __cause__ to see uv's real failure output.
  3. Pre-install oxylabs in deployment images to skip the interactive path entirely.

Example fix

# before: subprocess.run(['uv','add','oxylabs']) fails outside a uv project

# after: install with the tool you actually use
pip install oxylabs
Defensive patterns

Strategy: try-catch

Validate before calling

try:
    import oxylabs  # noqa: F401
except ImportError:
    raise SystemExit("Run `pip install oxylabs` (or `uv add oxylabs` in a uv project) first")

Try / catch

try:
    tool = OxylabsAmazonSearchScraperTool(username=u, password=p)
except ImportError as e:
    raise SystemExit(f"Install oxylabs manually: {e}") from e

Prevention

When it happens

Trigger: Constructing OxylabsAmazonSearchScraperTool without oxylabs installed, confirming the install, while `uv add oxylabs` fails — no uv project in the working directory, uv absent, network/proxy failure, or resolver conflict.

Common situations: Non-uv projects (pip/requirements.txt) where `uv add` cannot work; CI containers lacking a pyproject.toml; air-gapped networks.
