配置文件 {config_path} 不存在

Error message

配置文件 {config_path} 不存在

What it means

Raised by trendradar's config loader when the resolved config file does not exist. Path resolution order: explicit config_path argument, then CONFIG_PATH env var, then default config/config.yaml. It fails fast with FileNotFoundError before any YAML parsing.

Solutions

1. Create or restore the config file at the path shown in the error message.
2. Set CONFIG_PATH to an absolute path: export CONFIG_PATH=/etc/trendradar/config.yaml.
3. Or pass the path explicitly to the load function if calling it programmatically.
4. For services, set the unit's WorkingDirectory to the repo root so config/config.yaml resolves.

Example fix

# before: CONFIG_PATH unset, cwd=/srv -> looks for /srv/config/config.yaml
# after:
export CONFIG_PATH=/opt/trendradar/config/config.yaml

from pathlib import Path

config_path = Path(os.environ.get("CONFIG_PATH", "config/config.yaml"))
if not config_path.is_file():
    raise SystemExit(f"missing config: {config_path}; set CONFIG_PATH")
config = load_config(str(config_path))

try:
    config = load_config()
except FileNotFoundError as e:
    print(f"{e}. Copy config/config.example.yaml to config/config.yaml and retry.")
    raise SystemExit(1)

When it happens

Trigger: Launching trendradar without config/config.yaml present; CONFIG_PATH pointing to a deleted or misspelled file; running from a cwd where the relative default path does not resolve.

Common situations: New deployment missing the config directory; CONFIG_PATH left over from an old install pointing at a removed location; running as a service/systemd unit whose WorkingDirectory differs from the repo root, breaking the relative default.
