WebPack

const webpack = require("@nativescript/webpack");
const NodePolyfillPlugin = require("node-polyfill-webpack-plugin")

module.exports = (env) => {
	webpack.init(env);

	webpack.chainWebpack(config => {
		// we add the plugin
		config.plugin('node-polyfill-webpack-plugin').use(NodePolyfillPlugin)
	  })

	return webpack.resolveConfig()
};

Additional context

  • I know axios and a couple of other packages are not up to date and use the util.js which could be where the issue is. However, I removed those packages & references to them which resulted in the same error.
  • I also added the polyfill package in webpack config so I don't think it is a polyfill issue?
  • I have looked at SO questions, reported issues, etc. without any progress. Any help would be appreciated.

调研方向

首先,使用提供的 NativeScript 版本复现 Android 启动失败,并检查自定义 webpack 配置,尤其是 NodePolyfillPlugin 的设置。跟踪报告的路径,依次经过 node_modules/util/util.js、webpack/bootstrap、console-browserify 和 @nativescript/core;完成的标准是构建后的应用能够启动且不出现 undefined env exception。
