# 7.5.USES=lua 和 Flavors

当使用 [`lua:module`](https://docs.freebsd.org/en/books/porters-handbook/uses/#uses-lua) 或 [`lua:flavors`](https://docs.freebsd.org/en/books/porters-handbook/uses/#uses-lua) 时，Port 会自动填充 `FLAVORS`，其中包含它所支持的 Lua 版本。不过，普通的应用程序（而不是 Lua 模块）通常不应使用这个功能；大多数嵌入或使用 Lua 的应用程序只需简单地使用 `USES=lua`。

`LUA_FLAVOR` 是可用的（并且必须使用）变量，用于依赖正确版本的依赖项，无论该 Port 是否使用了 `flavors` 或 `module` 参数。
