给出以下代码:

/* @flow */
interface IDefaultSettings {
  Drivers?: {},
  Options?: {}
}

const defaultSettings: IDefaultSettings = {
  Drivers: {},
  Options: {}
}

const settings: IDefaultSettings = {};

mergeSettings(settings);

function mergeSettings(settings: IDefaultSettings) {
  for (const [key, setting] of Object.entries(defaultSettings)) {
    switch(key) {
      case 'Drivers':
      case 'Options':
        settings[key] = setting;
        break;
    }
  }
}

将上面的代码放在Flow playgound中试试这个.

我收到这个lint错误,无法解决: "Cannot assign `setting` to `settings[key]` because an indexer property is missing in `IDefaultSettings` [1]."

为什么key在接口中需要使用索引器prop IDefaultSettings,当这个代码key从具有已知接口的对象中拉出时- 我的意思是,还有什么key …
