【问题描述】:
我尝试通过创建一个新的反应应用程序
npx create-react-app myapp
cd myapp
npm start
我正在使用反应版本 18.2.0
{
"name": "myapp",
"version": "0.1.0",
"private": true,
"dependencies": {
"@testing-library/jest-dom": "^5.16.4",
"@testing-library/react": "^13.3.0",
"@testing-library/user-event": "^13.5.0",
"react": "^18.2.0",
"react-dom": "^18.2.0",
"react-scripts": "5.0.1",
"web-vitals": "^2.1.4"
},
然后我出错了,我的应用程序也没有在浏览器中打开。 (我尝试手动打开本地主机但没有运气)
(node:8168) [DEP_WEBPACK_DEV_SERVER_ON_AFTER_SETUP_MIDDLEWARE] DeprecationWarning: 'onAfterSetupMiddleware' option is deprecated. Please use the 'setupMiddlewares' option.
(Use `node --trace-deprecation ...` to show where the warning was created)
