调研方向

首先，使用 ionic cordova build android，通过所示的 config/webpack.config.js 配置复现该失败。阅读第 22 行的 node_modules/webpack-obfuscator/dist/index.js 以及周围的 Webpack 堆栈，包括 ionic-app-scripts 3.2.4。完成的标准是确定不兼容或缺失的集成细节，并让构建越过 emit 错误。

描述

Hi - I'm not sure if this is the right place to post this but I could use some help.

I'm developing a project using Cordova/Ionic 3, and I'm trying to add the javascript-obfuscator plugin following this guide.

I've installed the javascript-obfuscator package via NPM, I've got a config folder with a copy of webpack.config.js that's being recognised by my project and used. I've added my plugin:

var JavaScriptObfuscator = require('webpack-obfuscator');

And in the plugins section:

  plugins: [
    new Dotenv({
      path: '.env.dev', // load this now instead of the ones in '.env'
      systemvars: true, // load all the predefined 'process.env' variables which will trump anything local per dotenv specs.
      silent: true // hide any errors
    }),
    ionicWebpackFactory.getIonicEnvironmentPlugin(),
    ionicWebpackFactory.getCommonChunksPlugin(),
    new JavaScriptObfuscator({
      stringArrayEncoding: 'base64'
    })
  ],

But when I run the ionic cordova run android command, I get the following output:

PS C:\MobileDev\sd-site-induction> ionic cordova build android
> ionic-app-scripts.cmd build --target cordova --platform android

[ERROR] An error occurred while running subprocess ionic-app-scripts.

Any ideas why this is happening, or what the error means?

Thanks,
