我正在尝试使用 Angular 创建以太坊 dapp。我正在关注那篇文章：https :
//medium.com/blockchain-developer/learn-how-to-create-your-own-dapp-with-angular-9-part-iv-truffle-7704dc4269ab
但是，当我添加web3 to app with npm install --save web3，并在代码中调用它，我遇到了以下问题：
Error: ./node_modules/swarm-js/node_modules/eth-lib/lib/bytes.js
Module not found: Error: Can't resolve 'crypto' in '/home/szymon/dev/dapp/node_modules/swarm-js/node_modules/eth-lib/lib'

Module not found: Error: Can't resolve 'http' in '/home/szymon/dev/dapp/node_modules/web3-providers-http/src'
Error: ./node_modules/xhr2-cookies/dist/xml-http-request.js
Module not found: Error: Can't resolve 'http' in '/home/szymon/dev/dapp/node_modules/xhr2-cookies/dist'
Error: ./node_modules/web3-providers-http/src/index.js
Module not found: Error: Can't resolve 'https' …在我的项目中，我正在做一些清理工作并决定将所有内容移至 JUnit5。
到目前为止，我一直在使用
@RunWith(JUnitPlatform.class)
现在我想将它迁移到@ExtendWith。这个 JUnitPlatform.class 在 JUnit5 中是否有任何等价物？
