从版本2迁移到Webpack版本4时，我看到以下未定义的错误。似乎找不到问题。
下面是我的webpack配置
new HtmlWebpackPlugin({
template: './src/app/sample-error.ejs',
chunksSortMode: 'dependency',
filename: 'jpmol-error.html',
chunks: [
'polyfills',
'styles-jpmol',
'main-jpmol-error'
]
}),
在尝试启动Webpack开发服务器时，我得到以下错误ID。

我更新了所有webpack插件以使其与版本4一致，但无法克服此错误。
