uv lock # 根據 pyproject.toml 創建/更新 lockfile，但只要 uv.lock 符合目前的安裝條件，則不會顯式升級套件
uv lock --locked # 檢查 lockfile 是否是最新的 (也可以使用 --check)
uv lock --upgrade-package pydantic # 升級指定 package
uv lock --upgrade # 升級所有 package。類似 poetry update，但不會更新到環境內，只會更新 uv.lock 檔
uv sync # 如果 lockfile 不存在，會安裝最新且符合條件的套件，相當於 poetry install + poetry update
uv sync --group test # 額外安裝 test group 的套件
uv sync --all-groups # 額外安裝所有 group 的套件
uv sync --frozen # 不會更新 lockfile，而是根據 uv.lock 來安裝套件。相當於 poetry install，但如果 lock 檔案不存在會報錯
