谢谢.
解决方案
现在要牢记 TypeScript 3.6.4已经发布.不过，可以在下面阅读并非真正有效的内容.
TypeScript <= 3.6.3出现了此问题，在isParameterPropertyDeclaration中处理无父节点.
如果安装3.7(dev或新的beta)，它将可以正常编译.
注意:如果在构建中收到有关TS版本的ERROR，只需通过tsconfig禁用它.
为此，请使用disableTypeScriptVersionCheck
"angularCompilerOptions": {
"disableTypeScriptVersionCheck": true
},
"compilerOptions": {
...
如果出现其他任何问题，请按照评论聊天.

解决方案
Keep in mind now TypeScript 3.6.4 is out. Still, it's ok to read below what wasn't really working.
TypeScript <= 3.6.3 presents this issue, Handle parentless nodes in isParameterPropertyDeclaration.
If you install 3.7 (dev or the new beta), it will compile fine.
Note: if you receive an ERROR on building, regarding the TS version, just disable it via tsconfig.
For that use disableTypeScriptVersionCheck
"angularCompilerOptions": {
"disableTypeScriptVersionCheck": true
},
"compilerOptions": {
...
