运行ionic cordova run ios --prod命令后，我收到以下错误。我正在使用离子3并希望在ios仿真器上运行。

Latish回答，但这可能是因为双重声明相同变量和在某个组件中声明不好：

export class MyComponent implements OnInit {

  centres : Array<any> = [];
  groups: Array<any> = [];
  headerList = [];
  actions= [];
  headerList :  [];  // <-- This is the culprit
}

注意带冒号的第二个headerList声明而不是equals。我看到即使是相当现代的IDE也没有报告这个问题。删除第二个声明会导致错误。

另外需要注意的是，一旦出现第一个错误，编译器将无法在监视模式下正确重启。您应该按CTRL-C然后重新启动它。

这个问题在2.4.2中为我提供。
