请安装 schedule 库: pip install schedule

Error message

请安装 schedule 库: pip install schedule

What it means

ImportError raised in StockScheduler.__init__ when the third-party 'schedule' package cannot be imported. The stdlib has no scheduler of this shape, so the dependency is required; the code logs the remediation hint and re-raises as an explicit ImportError with the pip command. It fails at scheduler construction, before any scheduling happens.

Solutions

1. Install the package: pip install schedule (or pip install -r requirements.txt which pins it)
2. Add 'schedule' to the deployed image's requirements and rebuild
3. If you hit a resolver conflict, align versions so 'schedule' installs cleanly alongside the pinned stack
4. If you never use --schedule mode, avoid constructing StockScheduler rather than removing the dependency ad hoc

Example fix

# before
$ python main.py --schedule
ImportError: 请安装 schedule 库

# after
$ pip install schedule
$ python main.py --schedule

import importlib.util

def schedule_available() -> bool:
    return importlib.util.find_spec("schedule") is not None

try:
    scheduler = StockScheduler(schedule_time="09:30")
except ImportError:
    log.error("Schedule mode requires 'schedule'; install deps or drop --schedule")
    raise SystemExit(2)

When it happens

Trigger: Instantiating the scheduler in an environment where 'schedule' is not installed — a fresh venv, a Docker image built from a partial requirements install, or a deployment where requirements.txt was trimmed.

Common situations: Running --schedule mode without installing dev/optional deps; CI cache or slim image missing the package; dependency resolver dropped it after a version conflict; running from source without pip install -r requirements.txt.
