Question

所以我要创建这个React网站，但不是JSX，而是TSX。我正在使用webpack和Babel。在运行webpack-dev-server

时遇到此错误需要帮助

ERROR in ./src/index.tsx
Module build failed (from ./node_modules/babel-loader/lib/index.js):
...
Error while parsing config - JSON5: invalid character '�' at 1:1

这是我的.babelrc

{
    "presets": [
        "@babel/preset-env",
        "@babel/preset-typescript",
        "@babel/preset-react"
    ],
    "plugins": [
        "@babel/proposal-class-properties",
        "@babel/proposal-object-rest-spread"
    ]
}

这是我的webpack.config.js：

const nodeExternals = require('webpack-node-externals');

module.exports = {
    mode: 'development',
    watch: true,
    entry: './src/index.tsx',
    target: 'node',
    externals: [nodeExternals()],
    output: {
        filename: 'bundle.js',
        path: __dirname + '/dist'
    },
    resolve: {
        extensions: ['.ts', '.tsx', '.js', '.json', '.scss']
    },
    devtool: 'source-map',
    devServer: {
        publicPath: '/',
        contentBase: './public',
        hot: true
    },
    module: {
        rules: [{
                test: /\.tsx?$/,
                exclude: '/node_modules/',
                loader: 'babel-loader'
            },
            ...
            {
                enforce: 'pre',
                test: /\.js$/,
                loader: 'source-map-loader'
            }
        ]
    }
};

index.tsx

import React from 'react';
import ReactDOM from 'react-dom';
import './index.scss';
import App from './components/App/App';
import * as serviceWorker from './serviceWorker';
import store from './store';
import { Provider } from 'react-redux';

ReactDOM.render(
  <Provider store={store}>
    <App />
  </Provider>,
  document.getElementById('root')
);
serviceWorker.unregister();

我到处搜索过，但没有令人满意的结果。希望我能在这个论坛上得到更多的投入。

我遇到这样的错误，这是我的tsconfig.json文件中的一个错字。

为什么会出现此Babel JSON配置错误？
