TLDR: [email protected] is inpatible with React 18. As a workaround, you can downgrade your application to React 17.

While resolving: [email protected]

npm ERR! Found: [email protected]
npm ERR! node_modules/react
npm ERR!   react@"^18.0.0" from the root project

Those first three lines indicate that npm identified React 18 as your project's dependency.

Could not resolve dependency

npm ERR! peer react@"^16.8.0 || ^17.0.0" from [email protected]
npm ERR! node_modules/semantic-ui-react
npm ERR!   semantic-ui-react@"^2.1.2" from the root project

These 3 lines list semantic-ui-react's peer dependency, meaning it expects your project to have either React 16.8 or React 17 as dependency.

Fix the upstream dependency conflict

There are two ways to address this conflict:

1. Downgrade your project to React 17 using npm install react@17
2. Override semantic-ui-react's using yarn's Selective Resolution feature. Inside your package.json:

"resolutions": {
    "semantic-ui-react/react": "^18.0.0"
}

You can use this article it helped me solved the same problem when i wanted to install semantic-ui with react 18 it will probably help you with other frameworks that doesn't patible with react 18
