Chart.js错误:您可能需要适当的加载器来处理此文件类型
我当前正尝试在Reaction应用程序中使用Chart.js
,但在构建应用程序时出现此错误
ERROR in ./node_modules/chart.js/dist/chart.esm.js
Module parse failed: D:MyApp
ode_moduleschart.jsdistchart.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,看看是否有人也遇到过同样的问题,但没有成功。
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

我以为错误会告诉我需要安装哪个加载器才能与Chart.js
一起使用,但它没有指定。如果有人知道我需要安装哪个加载器,以及我应该把它放在我的文件中的什么位置,那就太棒了。Tia!
解决方案
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。
