我试图在我的re-frame/reagent/leiningen项目中使用cljsjs/vis，但是在将此库导入命名空间时出现错误。

cljsjs/vis in namespace required but not available

尝试使用其他库进行图表/数据可视化，但结果仍然相同。将 JS 库导入 clojurescript 项目似乎有问题。

shadow-cljs 不支持 CLJSJS 包。相反，您安装那些 CLJSJS 包代表的原始 npm 包并直接使用它。

所以而不是

(ns my-project
  (:require [cljsjs.vis]))

;; accessing vis via js/WhateverGlobalItUses

你做

(ns my-project
  (:require ["vis-network" :as vis]))

;; then use "vis" directly

npm 版本被拆分为多个单独的包，因此只需包含您想要使用的任何内容。

shadow-cljs 文档使用npm 包进行了详细说明。还有一个较旧的示例 repo使用vis-network.
