如何在Fulcro中打包软件包？

Question

我正在Fulcro 3 Dev Guide项目的[使用Javascript React组件使用Fulcro Template部分中，尝试导入Material-UI React组件。

我添加了带有npm install --save @material-ui/core的程序包并修改了demo_ws.cljs文件

(ns app.demo-ws
  (:require [com.fulcrologic.fulcro.components :as fp]
            [nubank.workspaces.core :as ws]
            [nubank.workspaces.card-types.fulcro3 :as ct.fulcro]
            [com.fulcrologic.fulcro.mutations :as fm]
            [com.fulcrologic.fulcro.dom :as dom]
            ["@material-ui/core/Button" :default material-button]
            [com.fulcrologic.fulcro.algorithms.react-interop :as interop]
            ))

(def ui-button (interop/react-factory material-button))

(fp/defsc FulcroDemo
  [this {:keys [counter]}]
  {:initial-state (fn [_] {:counter 0})
   :ident         (fn [] [::id "singleton"])
   :query         [:counter]}
  (dom/div
    (str "Fulcro counter demo [" counter "] ")
    (ui-button
      {:variant "contained"
       :color "primary"}
      "Another Button")
    (dom/button {:onClick #(fm/set-value! this :counter (inc counter))} "+")))

(ws/defcard fulcro-demo-card
  (ct.fulcro/fulcro-card
    {::ct.fulcro/root       FulcroDemo
     ::ct.fulcro/wrap-root? true}))

并且在控制台中出现错误：

Uncaught TypeError: Cannot read property 'root' of undefined
    at eval (Button.js:323)
    at renderWithHooks (react-dom.development.js:16242)
    at updateForwardRef (react-dom.development.js:18125)
    at beginWork$1 (react-dom.development.js:20187)
    at HTMLUnknownElement.callCallback (react-dom.development.js:337)
    at Object.invokeGuardedCallbackImpl (react-dom.development.js:386)

事实证明，这不是提到的inthisplaces的根本问题。

[对我有用的是，将hoist-non-react-statics版本3.3.0添加为指向here并更新react和react-dom程序包。
