添加插件

pnpm --filter @notes/docs i remark-math rehype-katex -r
import remarkToc from "remark-toc";
import remarkMath from "remark-math";
import { defineConfig } from "astro/config";
//***
export default defineConfig({

    // ***
    markdown: {
        remarkPlugins: [
            remarkMath,
        ],
        rehypePlugins: [
            rehypeKatex,
             
         ],
})

使用

$$
 \frac{abc123}{xyz123}
$$

$$
\overline{X}=\frac{1}{n}\sum_{i=1}^{n}x_i
$$
abc123xyz123\frac{abc123}{xyz123}
X‾=1n∑i=1nxi\overline{X}=\frac{1}{n}\sum_{i=1}^{n}x_i
