一. 问题

在进行组件库开发时，添加 ant-design-vue 的 less 文件时，报：Internal server error: [less] Inline JavaScript is not enabled. Is it set in your options?

具体错误信息：

 [vitepress] Internal server error: [less] Inline JavaScript is not enabled. Is it set in your options?
  Plugin: vite:css
  File: C:/Users/guoyongqi/Desktop/jr/jr-design/node_modules/ant-design-vue/es/style/color/bezierEasing.less:110:0
  108|  // resolve error: `ReferenceError: colorPalette is not defined`
  109|  // https://github.com/ant-design/ant-motion/issues/44

10:50:35 [vitepress] Pre-transform error: [less] Inline JavaScript is not enabled. Is it set in your options?

从最后一行，可以看到真正原因是：[less] Inline JavaScript is not enabled. Is it set in your options?（未启用内联JavaScript。它在你的选项中设置了吗?）

二. 解决方法

在 vite.config.js 配置中添加如下即可，开启内联JavaScript：

export default defineConfig({
  css: {
    loaderOptions:{
      less:{
        javascriptEnabled: true
      }
    }
  },
})
