これが私のwebpack.config.jsです
"use strict";
module.exports = {
entry: ['./main.js'],
output: { path: __dirname, filename: 'bundle.js' },
module: {
loaders: [
{
test: /.js?$/,
loader: 'babel-loader',
exclude: /node_modules/,
query: {
presets: ['es2015', 'react']
}
},
{test: /\.json$/, loader: "json"},
]
},
externals: {
React: 'react',
},
target: "node",
};
そしてMain.js
import React from 'react';
import ReactDOM from 'react-dom';
import {Table, Column, Cell} from 'fixed-data-table';
import Chart from 'chartjs';
import jQuery from 'jquery';
import vis from 'vis';
import babel from 'babel-core';
Bundle.jsが私のIndex.htmlに挿入されます。次に、ブラウザはエラーを出します:
Uncaught ReferenceError: process is not defined
at Object.measureMethods (bundle.js:1297)
at Object.<anonymous> (bundle.js:530)
at __webpack_require__ (bundle.js:20)
at Object.<anonymous> (bundle.js:288)
at __webpack_require__ (bundle.js:20)

at __webpack_require__ (bundle.js:20)
at Object.<anonymous> (bundle.js:110)
at __webpack_require__ (bundle.js:20)

このエラーを解消するには、webpack.config.jsで何を変更すればよいですか?
プラグインを追加して、(webpack構成で)環境を定義する必要があります。
plugins: [
new webpack.DefinePlugin({
'process.env.NODE_ENV': JSON.stringify('development')
})
],
