Answer 1

TLDR:semantic-ui-react@2.1.2是 incompatible with React 18 .作为一种解决方法，您可以将应用程序降级到 react 17 .
解决时:camp-project@0.1.0

npm ERR! Found: react@18.1.0
npm ERR! node_modules/react
npm ERR!   react@"^18.0.0" from the root project

前三行表明 npm 识别了 react 18 作为您项目的依赖项。
无法解决依赖关系

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

这 3 行列出了 semantic-ui-react的对等依赖，这意味着它希望您的项目具有 react 16.8 或 react 17 作为依赖。
修复上游依赖冲突
有两种方法可以解决这种冲突:

将您的项目降级到 react 17 使用 npm install react@17

覆盖 semantic-ui-react使用 yarn 的Selective Resolution feature .在你的 package.json 中:

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