Video reproducing the error/missing css
我知道,该问题在堆栈溢出时已经过时,例如React + Material-UI - Warning: Prop className did not match。
但是,当我尝试搜索并研究人们的解决方案时,没有明确的答案。我能找到的所有答案都不符合我的要求。
我的堆栈:
从next.js & material-ui - getting them to work之类的问题的答案中我可以得出的结论是,在涉及Next JS和Material UI时,存在某种程度的不兼容。
按代码分类,这是我的Appbar组件。最初,我没有导出我的useStyles
对象,但最终却以可怜的尝试将其与Material UI's express guide to "server rendering"一起使用来导出它。必须有一个不涉及像我拥有的每个文件一样进行更改的修补程序。

我只是在互联网的随机区域四处寻找该错误的答案,在Github问题上偶然npm install
将styled-components
作为this answer的一部分(因为它们有一个与Material UI中名为ServerStyleSheet
的对象非常相似的对象(与Material UI的ServerStyleSheets
相比),因此显然不起作用。
但是...... 我最终只是使用ServerStyleSheet
修复程序尝试使其与Material UI的ServerStyleSheets
对象一致,并结束了这个新的_document.js
。
我仍然很傻,我能够重构一个完全不同的修复程序来完成这项工作,但是我对其进行了测试,它完全解决了问题,现在重新加载就可以了。
import Document, { Html, Head, Main, NextScript } from 'next/document';
import {ServerStyleSheets} from "@material-ui/styles";
class MyDocument extends Document {
static async getInitialProps(ctx) {
const sheet = new ServerStyleSheets();
const originalRenderPage = ctx.renderPage;
try{
ctx.renderPage = () => originalRenderPage({
enhanceApp: App => props => sheet.collect(<App {...props}/>)
});
const initialProps = await Document.getInitialProps(ctx);
return { ...initialProps,
styles: (
<>
{initialProps.styles}
{sheet.getStyleElement()}
</>
)
}
} finally {
ctx.renderPage(sheet)
}
}
render() {
return (
<Html>
<Head>
<link rel="shortcut icon" type="image/png" href="../static/favicon.ico"/>
<style>{`body { margin: 0 } /* custom! */`}</style>
<meta name="viewport"content="width=device-width, initial-scale=1.0" />
</Head>
<body className="custom_class">
<Main />
<NextScript />
</body>
</Html>
)}
}
export default MyDocument;
如果您想了解它的工作原理是多么疯狂,这里是针对styled-components
中相同错误的解决方案:
导出默认的MyDocument;
import Document from 'next/document'
import { ServerStyleSheet } from 'styled-components'
export default class MyDocument extends Document {
static async getInitialProps (ctx) {
const sheet = new ServerStyleSheet()
const originalRenderPage = ctx.renderPage
try {
ctx.renderPage = () =>
originalRenderPage({
enhanceApp: App => props => sheet.collectStyles(<App {...props} />)
})
const initialProps = await Document.getInitialProps(ctx)
return {
...initialProps,
styles: (
<>
{initialProps.styles}
{sheet.getStyleElement()}
</>
)
}
} finally {
sheet.seal()
}
}
}
我希望这可以帮助某人解决Material-UI + Next.js的麻烦

就我而言,在 makeStyle 钩子中添加 { name: "MuiExample_Component" }
是出于某种原因。我在互联网上挖掘时找到了这个解决方案。如果有人能告诉我这是否是一个好的解决方案,我将不胜感激,但这是代码:
const useStyles = makeStyles({
card: {
backgroundColor: "#f7f7f7",
width: "33%",
},
title: {
color: "#0ab5db",
fontWeight: "bold",
},
description: {
fontSize: "1em"
}
}, { name: "MuiExample_Component" });
