Error message

`oxylabs` package not found, please run `uv add oxylabs`

What it means

Raised by OxylabsUniversalScraperTool.__init__ when oxylabs is not installed and the click.confirm install prompt is declined (default in non-interactive contexts). The ImportError points you to `uv add oxylabs` as the manual install command.

Solutions

  1. Pre-install oxylabs: pip install oxylabs or uv add oxylabs.
  2. Add it to your dependency lock/requirements file.
  3. Confirm with python -c "import oxylabs" before building the agent.

Example fix

# before
tool = OxylabsUniversalScraperTool()  # ImportError

# after
# pip install oxylabs
tool = OxylabsUniversalScraperTool(username=u, password=p)
Defensive patterns

Strategy: validation

Validate before calling

try:
    import oxylabs  # noqa: F401
except ImportError:
    raise SystemExit("Dependency missing: pip install oxylabs")

Try / catch

try:
    tool = OxylabsUniversalScraperTool(username=u, password=p)
except ImportError as e:
    raise SystemExit("Install oxylabs, then retry") from e

Prevention

When it happens

Trigger: OxylabsUniversalScraperTool(...) with oxylabs absent and the prompt answered no, or stdin closed (EOF) in CI/Docker so confirmation fails/declines.

Common situations: Headless deployments where interactive prompts cannot be satisfied; deliberate refusal of runtime installs.
