weibo user-posts limit must be an integer between 1 and ${MA

Error message

weibo user-posts limit must be an integer between 1 and ${MAX_LIMIT}

What it means

ArgumentError thrown by readLimit when the `limit` option is not an integer in [1, MAX_LIMIT] (MAX_LIMIT = 100). Empty/absent values default to 20; anything else must parse via Number() into a whole number within range. Note the thrown message interpolates MAX_LIMIT at runtime despite the literal string shown.

Solutions

1. Pass an integer between 1 and 100, e.g. `--limit 50`
2. Strip whitespace/units and validate numeric config values before invoking
3. Omit --limit entirely to use the default of 20

Example fix

// before
weibo user-posts 12345 --limit "1,000"
// after
weibo user-posts 12345 --limit 100

const limit = Number(rawLimit);
if (!Number.isInteger(limit) || limit < 1 || limit > 100) {
    throw new Error('limit must be an integer between 1 and 100');
}
await weiboUserPosts({ id, limit });

function isValidLimit(v) {
    return Number.isInteger(v) && v >= 1 && v <= 100;
}

try {
    await weiboUserPosts({ id, limit });
} catch (err) {
    if (err instanceof ArgumentError && String(err.message).includes('limit')) {
        console.error('Pass an integer between 1 and 100, or omit --limit for the default of 20.');
    } else throw err;
}

When it happens

Trigger: Passing `--limit 0`, `--limit 101`, `--limit abc`, `--limit 12.5`, or any non-numeric string to `weibo user-posts`.

Common situations: Copy-pasting a limit with a trailing space/unit ('20 条'); passing a float or comma-formatted number ('1,000'); setting limit from a config/env var containing garbage; assuming the cap is higher than 100.
