导入错误：在使用 @material-ui/core/styles/ThemeProvider/ 和 @material-ui/core/styles/createMuiTheme/ 时找不到模块

Question

Getting the following error while using @materail-ui/core library

Module not found: Can't resolve '@material-ui/core/styles/ThemeProvider' in 'Z:\\module-builder\\web\\src\\Components'.

Below is the code I am using, have installed @material-ui/core in node modules

import React, { createContext, useContext, useState } from 'react';
import createMuiTheme from '@material-ui/core/styles/createMuiTheme';
import UploadIcon from '@material-ui/icons/CloudUpload';
import WarningIcon from '@material-ui/icons/Warning';
import MuiThemeProvider from '@material-ui/core/styles/ThemeProvider';
import Snackbar from '@material-ui/core/Snackbar';
import { TRASH_ICON } from '../Assets/Images/svg';
import Slide from '@material-ui/core/Slide';

interface Options {
    message: string;
    variant: number;
    timeout?: number;
}

function createTheme(backgroundColor: string) {
    return createMuiTheme({
        overrides: {
            MuiSnackbarContent: {
                root: { backgroundColor }
            }
        }
    });
}

const errorSnack = createTheme('#cc5200');
const infoSnack = createTheme('#0088cc');
const successSnack = createTheme('#00a14f');

Error at Browser when Loading

Answer 1

createMuiTheme is now deprecated in newer @material-ui/core . Try use createTheme instead.

use this code added alias name to get your usages working correctly .

import {createTheme as createMuiTheme,ThemeProvider as MuiThemeProvider} from '@material-ui/core/styles';

using the above will solve your issue.
