无法解析 primereact 下拉列表中的“react-transition-group”

Question

我收到以下错误 -

Failed to compile
./node_modules/primereact/components/dropdown/DropdownPanel.js
Module not found: Can't resolve 'react-transition-group' in 'D:\my-app\node_modules\primereact\components\dropdown'

这是我的 package.json

  "dependencies": {
"@testing-library/jest-dom": "^5.11.4",
"@testing-library/react": "^11.1.0",
"@testing-library/user-event": "^12.1.10",
"@types/react-transition-group": "^4.4.1",
"primeflex": "^2.0.0",
"primeicons": "^4.1.0",
"primereact": "^6.1.0",
"react": "^17.0.1",
"react-dom": "^17.0.1",
"react-scripts": "4.0.3",
"web-vitals": "^1.0.1"
},

在 App.js 中

import React, { useState } from 'react';
import { Dropdown } from 'primereact/dropdown'; //getting error after adding this line
import 'primeflex/primeflex.css';

我在这里缺少什么？

难道你只包含了类型，"@types/react-transition-group": "^4.4.1",但没有安装实际的包？

尝试使用 来安装该软件包npm install react-transition-group。该@types/*存储库仅包含类型，不包含代码。
