ionic3 项目打包出来的APP启动时白屏时间过长，解决方案
ionic cordova build android --release --prod
执行命令时却报如下错误：

  1. Error: ./src/app/main.ts
  2. Module not found: Error: Can't resolve './app.module.ngfactory' in 'D:\workspace\fs_app\src\app'
  3. resolve './app.module.ngfactory' in 'D:\workspace\fs_app\src\app'
  4.   using description file: D:\workspace\fs_app\package.json (relative path: ./src/app)
  5.     Field 'browser' doesn't contain a valid alias configuration
  6.   after using description file: D:\workspace\fs_app\package.json (relative path: ./src/app)
  7.     using description file: D:\workspace\fs_app\package.json (relative path: ./src/app/app.module.ngfactory)
  8.       no extension
  9.         Field 'browser' doesn't contain a valid alias configuration
  10.         D:\workspace\fs_app\src\app\app.module.ngfactory doesn't exist.ts
  11.         Field 'browser' doesn't contain a valid alias configuration
  12.         D:\workspace\fs_app\src\app\app.module.ngfactory.ts doesn't exist.js
  13.         Field 'browser' doesn't contain a valid alias configuration
  14.         D:\workspace\fs_app\src\app\app.module.ngfactory.js doesn't exist.json
  15.         Field 'browser' doesn't contain a valid alias configuration
  16.         D:\workspace\fs_app\src\app\app.module.ngfactory.json doesn't exist as directory

  19. [D:\workspace\fs_app\src\app\app.module.ngfactory.ts]
  20. [D:\workspace\fs_app\src\app\app.module.ngfactory.js]
  21. [D:\workspace\fs_app\src\app\app.module.ngfactory.json]
  22. [D:\workspace\fs_app\src\app\app.module.ngfactory]
  23.  @ ./src/app/main.ts 2:0-60

网上方法试了好多都不管用，之后又新建了一个空白的项目，发现报如下错误：

  1. Error: ./node_modules/tslib/tslib.es6.js
  2. Module build failed: TypeError: Cannot read property 'type' of undefined
  3.     at Object.getEffectiveTypeAnnotationNode (D:\myworkspace\test\node_modules\typescript\lib\typescript.js:9341:18)

  13.  @ ./src/app/app.module.ts 1:0-35
  14.  @ ./src/app/app.module.ngfactory.js
  15.  @ ./src/app/main.ts

本地环境有问题。最终找到解决方案:

  1. npm uninstall @ionic/app-scripts
  2. npm install @ionic/app-scripts@latest

之后新的项目报错和原来项目的报错都解决了，希望此文能够帮到你。
