Error message

获取视频分P信息失败: ${error?.message || error}

What it means

loadSelectedPart wraps the /x/web-interface/view call used to resolve the requested 分P (part) number. If the transport/API call throws (network, timeout, HTTP error) or the response envelope is malformed/non-zero code, it is converted into a Chinese-language CommandExecutionError prefixed 获取视频分P信息失败 with the underlying reason appended.

Solutions

1. Retry after a short wait if it was a timeout or risk-control blip (-352); reduce request frequency.
2. Verify the bvid/URL is correct and the video still exists (code -404 means deleted/invalid).
3. Refresh Bilibili cookies / re-login if auth-related codes appear.
4. Check network connectivity and proxy/VPN configuration before retrying.

Example fix

// caller-side retry around the CLI-level failure
try {
    await download(bvid, { page: 2 });
} catch (e) {
    if (String(e.message).startsWith('获取视频分P信息失败')) {
        await new Promise(r => setTimeout(r, 2000));
        await download(bvid, { page: 2 }); // retry once
    }
}

try {
    await download(bvid, { page: n });
} catch (e) {
    if (/获取视频分P信息失败/.test(e.message)) {
        if (/-404/.test(e.message)) { /* video gone: don't retry */ }
        else { /* transient (timeout/-352): wait and retry with backoff */ }
    } else throw e;
}

When it happens

Trigger: Using --page on a multi-P video while /x/web-interface/view fails: network timeout/DNS failure, Bilibili returning code != 0 (e.g. -404 video not found, -352 risk control, -403), rate limiting, or invalid cookie session.

Common situations: Typo in bvid or URL resolving to a removed video; triggering anti-bot risk control (-352) after many requests; expired cookies; offline/proxy network issues; --page given for a video whose data can't be fetched.
