我最近在我的项目中添加了一个名为“Antd”的优秀UI库。 https://ant.design/docs/react/introduce
它在我的开发环境中完美运行，我在Electron App中实现了很多组件。现在，当我将它打包发布时，我的Webpack完全停留在'91％的额外资产处理'阶段，最终V8耗尽内存。我没有进一步的输出。有什么地方我可以得到更详细的日志来确定最新情况吗？
有问题的网络包配置如下，它基于React Electron Boilerplate GitHub repo并且它为我提供了非常好的直到现在。

尝试设置devtool: 'cheap'。如果您有一个大型应用程序，生成源图可能会很昂贵。它是this issue完全获得后的临时解决方案
此外，似乎这个项目是基于电子反应 - 样板，我是它的核心维护者。你应该在那里打开bug报告/问题。

以下设置帮助我减少了堆内存，因为它不包括sourceMap文件。
devtool: false, // Webpack.
new webpack.optimize.UglifyJsPlugin({
sourceMap: shouldUseSourceMap
}),
或以下代码将有助于最新的webpack uglify插件。
> npm install uglifyjs-webpack-plugin --save-dev
// conf.js
const UglifyJsPlugin = require('uglifyjs-webpack-plugin');
module.exports = {
optimization: {
minimizer: [
new UglifyJsPlugin({
sourceMap: true,
}),
],
},
};
如果这仍然不能解决问题。下面的命令有助于增加堆内存，并通过链接了解有关堆内存的更多信息。
