Question

我正在使用Material-UI的paperbase高级主题：

https://material-ui.com/premium-themes/paperbase/

并查看源代码，我尝试执行以下操作：

// App.tsx

import * as React from 'react';
import './App.css';
import Paperbase from './components/Paperbase'

class App extends React.Component {
  public render() {
    return (
      <div className="App">
      <Paperbase />
      </div>
    );
  }
}

export default App;



// Paperbase.js

import React from 'react';
import PropTypes from 'prop-types';
import { createMuiTheme, withStyles } from '@material-ui/core/styles';
import { ThemeProvider } from '@material-ui/core/styles';
import CssBaseline from '@material-ui/core/CssBaseline';
import Hidden from '@material-ui/core/Hidden';
import Navigator from './Navigator';
import Content from './Content';
import Header from './Header';

let theme = createMuiTheme({
  typography: {
    h5: {
      fontWeight: 500,
      fontSize: 26,
      letterSpacing: 0.5,
    },
  },
  palette: {
    primary: {
      light: '#63ccff',
      main: '#009be5',
      dark: '#006db3',
    },
  },
  shape: {
    borderRadius: 8,
  },
});

theme = {
  ...theme,
  overrides: {
    MuiDrawer: {
      paper: {
        backgroundColor: '#18202c',
      },
    },
    MuiButton: {
      label: {
        textTransform: 'initial',
      },
      contained: {
        boxShadow: 'none',
        '&:active': {
          boxShadow: 'none',
        },
      },
    },
    MuiTabs: {
      root: {
        // marginLeft: theme.spacing(1),
      },
      indicator: {
        height: 3,
        borderTopLeftRadius: 3,
        borderTopRightRadius: 3,
        backgroundColor: theme.palette.common.white,
      },
    },
    MuiTab: {
      root: {
        textTransform: 'initial',
        margin: '0 16px',
        minWidth: 0,
        padding: 0,
        [theme.breakpoints.up('md')]: {
          padding: 0,
          minWidth: 0,
        },
      },
    },
    MuiIconButton: {
      root: {
        // padding: theme.spacing(1),
      },
    },
    MuiTooltip: {
      tooltip: {
        borderRadius: 4,
      },
    },
    MuiDivider: {
      root: {
        backgroundColor: '#404854',
      },
    },
    MuiListItemText: {
      primary: {
        fontWeight: theme.typography.fontWeightMedium,
      },
    },
    MuiListItemIcon: {
      root: {
        color: 'inherit',
        marginRight: 0,
        '& svg': {
          fontSize: 20,
        },
      },
    },
    MuiAvatar: {
      root: {
        width: 32,
        height: 32,
      },
    },
  },
  props: {
    MuiTab: {
      disableRipple: true,
    },
  },
  mixins: {
    ...theme.mixins,
    toolbar: {
      minHeight: 48,
    },
  },
};

const drawerWidth = 256;

const styles = {
  root: {
    display: 'flex',
    minHeight: '100vh',
  }
};

class Paperbase extends React.Component {
  state = {
    mobileOpen: false,
  };

  handleDrawerToggle = () => {
    this.setState(state => ({ mobileOpen: !state.mobileOpen }));
  };

  render() {
    const { classes } = this.props;

    return (
      <ThemeProvider theme={theme}>
        <div className={classes.root}>
          <CssBaseline />
          <nav className={classes.drawer}>
            <Hidden smUp implementation="js">
              <Navigator
                PaperProps={{ style: { width: drawerWidth } }}
                variant="temporary"
                open={this.state.mobileOpen}
                onClose={this.handleDrawerToggle}
              />
            </Hidden>
            <Hidden xsDown implementation="css">
              <Navigator PaperProps={{ style: { width: drawerWidth } }} />
            </Hidden>
          </nav>
          <div className={classes.appContent}>
            <Header onDrawerToggle={this.handleDrawerToggle} />
            <main className={classes.mainContent}>
              <Content />
            </main>
          </div>
        </div>
      </ThemeProvider>
    );
  }
}

Paperbase.propTypes = {
  classes: PropTypes.object.isRequired,
};

export default withStyles(styles)(Paperbase);

我收到一个错误消息：

Check the render method of `Paperbase`.

我对React非常陌生，并尝试在我的示例应用程序中使用此重要的ui主题。但是，不确定这里发生了什么以及为什么它抱怨render方法。我尝试在互联网上寻找可能的解决方案，但找不到适用于此情况的任何内容。有人可以帮助解决此问题吗？我肯定在做一些愚蠢的事情。

将ThemeProvider替换为MuiThemeProvider，要使用ThemeProvider，您应该使用：

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

React Material-UI：“检查“ Paperbase”的渲染方法”
