## css.preprocessorMaxWorkers

- **实验性：** [提供反馈](https://github.com/vitejs/vite/discussions/15835)
- **类型：** `number | true`
- **默认：** `0`（不会创建任何 worker 线程，而是在主线程中运行）
- **默认：** `true`

指定 CSS 预处理器可以使用的最大线程数。`true` 表示最多为 CPU 数量减 1。当设置为 `0` 时，Vite 将不会创建任何工作线程，而是在主线程中运行预处理器。

如果启用了这个选项，那么 CSS 预处理器会尽可能在 worker 线程中运行。`true` 表示 CPU 数量减 1。
根据预处理器选项，即使此选项未设置为 `0`，Vite 也可能会在主线程上运行预处理器。
