Question

我将ionic 4项目升级为使用angular 7，一切都在调试模式下工作，但是当我尝试进行生产编译时： 'ionic cordova build android --prod'，我得到以下输出：

ionic-app-scripts build --prod --target cordova --platform android   [20:24:15] ionic-app-scripts 3.2.4   ...   [20:24:44]打字稿错误               找不到“ @types”的类型定义文件。

[20:24:44] ionic-app-script任务：“构建”   [20:24:44]错误：无法翻译TypeScript   错误：无法翻译TypeScript       在errorCheckProgram（/Users/jesusotero/Projects/Bambuco/confiar/mardeconfianza/app/node_modules/@ionic/app-scripts/dist/aot/aot-compiler.js:119:39）       在对象。（/Users/jesusotero/Projects/Bambuco/confiar/mardeconfianza/app/node_modules/@ionic/app-scripts/dist/aot/aot-compiler.js:89:21）       在步骤（/Users/jesusotero/Projects/Bambuco/confiar/mardeconfianza/app/node_modules/@ionic/app-scripts/dist/aot/aot-compiler.js:32:23）       在Object.next（/Users/jesusotero/Projects/Bambuco/confiar/mardeconfianza/app/node_modules/@ionic/app-scripts/dist/aot/aot-compiler.js:13:53）       完成时（/Users/jesusotero/Projects/Bambuco/confiar/mardeconfianza/app/node_modules/@ionic/app-scripts/dist/aot/aot-compiler.js:4:58）   [ERROR]运行子流程ionic-app-scripts时发生错误。

ionic-app-scripts build --prod --target cordova --platform android退出代码为1。

我一直无法找到解决该问题的方法，因此，如果那里有人可以帮助我正确地解决该问题，我将非常感激。我的package.json是：

Answer 1

根据您共享的项目数据，是Ionic 3项目（3.9.6）。

Ionic 3并不是要与Angular 6+一起使用。

我建议检查Ionic 3参考应用程序的package.json并相应地降级您的依赖项。

Reference App v3 branch

Answer 2

ionic-app-script最近进行了更新，产生了此错误。

作为一种解决方法，您可以将package.json中的版本锁定为最后一个可用的版本：

“ @ ionic / app-scripts”：“ 3.2.3”

或降级

Answer 3

解决方案：使用ionic serve服务您的项目，然后更新src文件夹中的任何.ts文件并保存（ctrl + s），它将自动再次构建并服务该应用程序，并且错误将得到解决，希望：）。

这解决了我的问题。
