尝试导入错误：“淡入淡出”未从“@material-ui/core/styles”导出

Question

尝试了我在互联网上找到的所有可能的解决方案。我使用yarn - 下面的 package.json 升级了所有依赖项和包

"dependencies": {
  "@date-io/date-fns": "^1.3.13",
  "@date-io/moment": "^1.3.13",
  "@material-ui/core": "^5.0.0-beta.2",
  "@material-ui/icons": "^5.0.0-beta.1",
  "@material-ui/lab": "^5.0.0-alpha.41",
  "@material-ui/pickers": "^4.0.0-alpha.12",
  "@material-ui/styles": "^5.0.0-beta.2",
  "@testing-library/jest-dom": "^5.11.4",
  "@testing-library/react": "^11.1.0",
  "@testing-library/user-event": "^12.1.10",
  "axios": "^0.21.1",
  "date-fns": "^2.22.1",
  "moment": "^2.29.1",
  "react": "^17.0.2",
  "react-dom": "^17.0.2",
  "react-router": "^5.2.0",
  "react-router-dom": "^5.2.0",
  "react-scripts": "4.0.3",
  "web-vitals": "^1.0.1"
}

在升级软件包之前我使用了：

import {
  MuiPickersUtilsProvider,
  KeyboardDatePicker,
} from '@material-ui/pickers';

之后我导入了这些：

import LocalizationProvider from '@material-ui/lab/LocalizationProvider';
import AdapterDateFns from '@material-ui/lab/AdapterDateFns';

并尝试了下面的代码：

                <LocalizationProvider dateAdapter={AdapterDateFns}>
                    <Grid container justifyContent="space-around">
                        <DatePicker 
                            disableToolbar 
                            variant="inline" 
                            format="DD/MM/yyyy"  
                            margin="normal" 
                            label="Date" 
                            name="date"
                            value={values.date}
                            onChange={(date) => handleInputChange(convertToDefault(date))}
                        />
                    </Grid>
                </LocalizationProvider>

你能帮我吗？还蛮麻烦的:/

使用这个版本对我来说效果很好...yarn add @material-ui/core@4.11.4 @material-ui/pickers

"@material-ui/core": "4.11.4",
"@material-ui/pickers": "^3.3.10",
