A loose `^2.2.10` range let npm pull a newer build of the QQ Music API. The
library went ESM in 2.3.x: an ESM-only 2.3.0/2.3.1 throws ERR_REQUIRE_ESM on
load, so the embedded server never binds port 3200 and every QQ request
(including /getQQLoginQr) fails downstream with ECONNREFUSED — the QR code never
appears and cookies look broken.
- Pin to `~2.4.0` (verified: loads via the bot's native ESM import, exposes the
Koa app, and every endpoint qq.ts calls returns the exact shapes it parses —
QR, recommend, lyric, play, playlist detail). Blocks the broken 2.3.0/2.3.1
and any future 2.5 migration. NOTE: 2.4.x requires Node >=20.17 (or >=22.9).
- Add describeQqApiStartupError(): on startup failure, log an actionable error
(ERR_REQUIRE_ESM → version-pin hint; engine mismatch → Node-upgrade hint)
instead of a generic warning, so this is obvious from the logs next time.
- README: troubleshooting entry for "QQ 二维码不弹 / 登录失败 / cookie 无法使用"
and the version/Node note in the dependency table.
