我正在尝试将styled-jsx与一些代码一起使用。但是,无论我做什么,我似乎都会出错
index.js:1437 Warning: Received `true` for a non-boolean attribute `jsx`.
If you want to write it to the DOM, pass a string instead: jsx="true" or jsx={value.toString()}.
in style (at App.js:12)
in div (at App.js:9)
in Test (created by Route)
in Route (at App.js:29)
in Router (created by BrowserRouter)
in BrowserRouter (at App.js:27)
in App (at src/index.js:7)
我尝试重新安装node_modules,确保我的配置正常,并测试了不同的版本。
我的package.json,
{
"name": "preview",
"version": "0.1.0",
"private": true,
"dependencies": {
"contentful": "^7.4.1",
"react": "^16.8.6",
"react-dom": "^16.8.4",
"react-router-dom": "^4.3.1",
"react-scripts": "^3.0.1",
"socket.io-client": "^2.2.0",
"styled-jsx": "^3.2.1"
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"eject": "react-scripts eject"
},
"eslintConfig": {
"extends": "react-app"
},
"babel": {
"presets": [
"@babel/preset-stage-2"
],
"plugins": [
"styled-jsx/babel"
]
},
"browserslist": [
">0.2%",
"not dead",
"not ie <= 11",
"not op_mini all"
],
"proxy": "http://localhost:5000/"
}
我的示例React代码仍然抛出错误。
const Test = () => {
return (
<div>
<p>test
</p>
<style jsx>{
`
p {
color: red;
}
`
}
</style>
</div>)
}
class App extends Component {
render () {
return (
<Router>
<Route path='/test' component={Test}/>
</Router>
)
}
}
export default App;
根据文档,我希望没有任何错误消息

使用样式化组件。不支持嵌套样式。看https://github.com/zeit/styled-jsx/pull/260 避免这种情况:
<div>
<span>
<style jsx>{...}</style>
</span>
</div>

好的。因为我自己花了几个小时才解决这个问题,我希望我能帮助你们也有这个问题。
要将 styled-jsx 与 create-react-app 结合使用,您需要:
yarn add react-app-rewired customize-cra
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
与
"start": "react-app-rewired start",
"build": "react-app-rewired build",
"test": "react-app-rewired test",
package.json
旁边)文件 config-overrides.js
{ override, addBabelPlugin, addBabelPreset } = require('customize-cra');
module.exports = override(
addBabelPlugin('styled-jsx/babel')
);
.babelrc
中创建(仅在运行jest test
时使用){
"plugins": ["styled-jsx/babel"]
}
index.js
(或您将 React 安装到 DOM 的位置)中,在调用 ReactDOM.render(....) 之前,插入以下代码,
取自https://github.com/vercel/styled-jsx/issues/560#issuecomment-599371026
const _JSXStyle = require('styled-jsx/style').default;
if (typeof global !== 'undefined') {
Object.assign(global, { _JSXStyle });
}
很遗憾,但是如果没有它,这个复杂的配置有点变化无常。
仅当您将 yarn build
或 yarn test
与 create-react-app 结合使用时,才需要第 4 步和第 5 步。
