javascript - 未捕获的类型错误：更新到 Angular 7 后，ctorParameters.map 不是函数

问题描述

我最近将我的 Angular 项目更新为 Angular 7。现在，当我从 CLI 运行“ng serve --open”时，我收到以下错误：

Uncaught TypeError: ctorParameters.map is not a function at ReflectionCapabilities._ownParameters (core.js:1394) at ReflectionCapabilities.parameters (core.js:1426) at JitReflector.parameters (platform-b​​rowser-dynamic.js:48) at CompileMetadataResolver. _getDependenciesMetadata (compiler.js:10202) 在 CompileMetadataResolver._getTypeMetadata (compiler.js:10155) 在 CompileMetadataResolver.getNonNormalizedDirectiveMetadata (compiler.js:9784) 在 CompileMetadataResolver.loadDirectiveMetadata (compiler.js:9647) 在 _filterJitIdentifiers.forEach (compiler.js: 23148) 在 Array.forEach () 在 _filterJitIdentifiers.forEach (compiler.js:23147)

我的 package.json 看起来像这样：

    "@schematics/angular:directive": {
      "prefix": "app"
    }
  }
}

我假设存在一些依赖错误（当前，当我运行“npm audit fix”时，NPM 向我显示 auth0/angular-jwt 库需要 Angular 6，已经存在 GitHub 问题，但即使我临时删除该库，错误仍然存​​在）。

编辑：当我运行ng serve --open --aot它时。但为什么？

解决方案

Angular 发布了一个更新的版本7.0.2
，这个 bug 应该已经修复了，
运行ng update --all更新
