The dependencies are not being installed

Steps to reproduce:

npm install react-plotly.js plotly.js
npm start

Errors:

Module not found: Error: Can't resolve 'buffer/'
Module not found: Error: Can't resolve 'stream'
webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.
Module not found: Error: Can't resolve 'assert' in

使用 npm install react-plotly.js plotly.js，接著執行 npm start 來重現問題，然後檢查與缺少的 buffer/、stream 和 assert 模組相關的相依性與 webpack 設定。當回報的安裝與啟動命令在沒有這些模組解析錯誤的情況下完成時，即表示完成。
