【问题描述】：

我刚刚升级到 ionic 5 - 我的产品构建失败并出现以下问题：

    ERROR in ./node_modules/@ionic/angular/fesm2015/ionic-angular.js
Module build failed (from ./node_modules/@angular-devkit/build-optimizer/src/build-optimizer/webpack-loader.js):
TypeError: Cannot read property 'kind' of undefined

调试版本运行良好。

要解决这个问题，

确保你的依赖是

依赖：

"@angular/common": "8.2.13",
"@angular/core": "8.2.13",
"@angular/forms": "8.2.13",
"@angular/platform-browser": "8.2.13",
"@angular/platform-browser-dynamic": "8.2.13",
"@angular/pwa": "^0.803.23",
"@angular/router": "8.2.13",
"@angular/service-worker": "^8.2.14",
dev dependencies:

"@angular-devkit/architect": "^0.803.23",
"@angular-devkit/build-angular": "^0.803.23",
"@angular-devkit/core": "^8.3.23",
"@angular-devkit/schematics": "^8.3.23",
"@angular/cli": "^8.3.23",
"@angular/compiler": "8.2.13",
"@angular/compiler-cli": "8.2.13",
"@angular/language-service": "^8.2.14",
"@ionic/angular-toolkit": "^2.1.2",

特别注意，8.2.13 用于 angular 而不是我拥有的 8.1。
