提供者

import { ThemeProvider } from '@material-ui/core/styles'

         <Provider store={store}>
            <ConnectedRouter>
                <ThemeProvider theme={theme}>
                    <GlobalStyles/>
                    {/*<ErrorBoundary>*/}
                    {/*<Layout>*/}
                    <Component {...pageProps} />
                    {/*</Layout>*/}
                    {/*</ErrorBoundary>*/}
                </ThemeProvider>
            </ConnectedRouter>
        </Provider>

import Button from '@material-ui/core/Button'

            <div>
                <div>Log into APP</div>
                <Button>Test</Button>
            </div>

但我仍然在 Button.js 中遇到错误

在样式 (/Users/filipbrezina/Documents/Projekty/sportee-frontend/node_modules/
material-ui/core/Button/Button.js:33:78

有人能帮助我吗？我不知道我做错了什么😏

Answer 1

您定义/提供 theme 的方式有误:

你需要像这样提供它:

<ThemeProvider theme={theme({})}> {/* function call: theme({}) */}

或者，如果你这样定义它:

const theme = createMuiTheme({
  palette: {
    primary: {
      main: '#b5ddd1',
    },
    // you can add more options
  }
})

你可以这样提供:

<ThemeProvider theme={theme}>
