Angular cli build prod：TypeError：无法读取未定义的属性“种类”

Question

我尝试使用 Angular CLI 构建项目，ng build --prod但出现此错误：

TypeError 中的错误：无法读取未定义的属性“种类”

如果我使用 not 构建，--prod则不会出现任何错误

完整错误：

请记住，现在TypeScript 3.6.4 已经发布。不过，可以阅读下面没有真正起作用的内容。

TypeScript<= 3.6.3提出了这个问题，在 isParameterPropertyDeclaration 中处理无父节点。

如果您安装3.7（dev或新安装beta），它将编译正常。

注意：如果您收到ERROR关于 TS 版本的on building，只需通过tsconfig.
为了那个用途disableTypeScriptVersionCheck

"angularCompilerOptions": {
  "disableTypeScriptVersionCheck": true
},
"compilerOptions": {
 ...

如果出现任何其他问题，请关注评论的聊天。
