javascript - Chart.js 错误 : You may need an appropriate loader to handle this file type

Question

我目前正在尝试使用 Chart.js在我的 react 应用程序中，但是当我去构建我的应用程序时，我遇到了这个错误

ERROR in ./node_modules/chart.js/dist/chart.esm.js
Module parse failed: D:\MyApp\node_modules\chart.js\dist\chart.esm.js Unexpected token (6613:12)
You may need an appropriate loader to handle this file type.
|         if (intermediateIndex1 !== startIndex && intermediateIndex1 !== lastIndex) {
|           decimated.push({
|             ...data[intermediateIndex1],
|             x: avgX,
|           });
 @ ./src/imports/Dashboard/Dashboard.js 21:12-31
 @ ./src/App.js
 @ ./src/index.js
 @ multi babel-polyfill ./src/index.js

我尝试在网上搜索，看看是否有其他人遇到过同样的问题，但我没有运气。
下面是我的 Webpack 配置文件:

const path = require('path');

module.exports = {
    entry: ['babel-polyfill', './src/index.js'],
  output: {
    path: path.join(__dirname, 'public'),
    filename: 'bundle.js'
  },
  module: {
    rules: [{
      loader: 'babel-loader',
      test: /\.jsx?$/,
      exclude: /node_modules/
    }, {
      test: /\.s?css$/,
      use: [
        'style-loader',
        'css-loader',
        'sass-loader'
      ]
    },{
        test: /\.(jpe?g|png|gif|svg|mp3)$/i,
        loaders: [
            'file-loader?hash=sha512&digest=hex&name=[hash].[ext]',
            'image-webpack-loader?bypassOnDebug&optimizationLevel=7&interlaced=false'
        ]
    }
    ]
  },
  devtool: 'cheap-module-eval-source-map',
  devServer: {
    contentBase: path.join(__dirname, 'public'),
    historyApiFallback: true
  }
};

这是我的 bablerc 文件

{
    "presets": [
      "env",
      "react",
      "stage-0"
    ],
    "plugins": [
      "transform-class-properties"
    ]
  }

这是我安装的依赖项列表

  },

我预计错误会告诉我需要安装什么加载器才能与 Chart.js 一起使用但它没有具体说明。如果有人知道我需要安装哪个加载器以及我应该将它放在我的文件中的哪个位置，那就太棒了。蒂亚!

Answer 1

Chart.js 版本 3 不兼容。将其更改为 ^2.9.4。和你我一样的问题已经解决了。
