打字稿反应HOC错误与hoist-non-react-statics

Question

我正在使用react和typescript以及hoist-non-react-statics并试图创建一个HOC。我已经将代码简化为一个人为的HOC，它用div包装组件。

const withWrapper = <TProps extends {}>(
  WrappedComponent: React.ComponentType<TProps>,
) => {
  const WithWrapper: React.FC<TProps> = (props: TProps) => (
    <div>
      <WrappedComponent {...props} />
    </div>
  )

  WithWrapper.displayName = `WithWrapper(${
    WrappedComponent.displayName || WrappedComponent.name || 'Component'
  })`

  return hoistNonReactStatics(WithWrapper, WrappedComponent)
}

但得到错误：

Argument of type 'ComponentType<TProps>' is not assignable to parameter of type 'ComponentType<any>'.
  Type 'ComponentClass<TProps, any>' is not assignable to type 'ComponentType<any>'.
    Type 'ComponentClass<TProps, any>' is not assignable to type 'FunctionComponent<any>'.
      Type 'ComponentClass<TProps, any>' provides no match for the signature '(props: any, context?: any): ReactElement<any, string | ((props: any) => ReactElement<any, string | any | (new (props: any) => Component<any, any, any>)> | null) | (new (props: any) => Component<any, any, any>)> | null'.

     return hoistNonReactStatics(WithWrapper, WrappedComponent)
                                              ~~~~~~~~~~~~~~~~

为什么这个无效？让它通过的唯一方法是通过施放WrappedComponent as React.ComponentType<any>。

您的代码可以与[email protected]，@types/[email protected]和@types/[email protected]一起使用。

代码中唯一不正确的事情是使用单个管道（|）而不是双管道。单个管道用于按位OR，而double用于短路 - 我相信你的意思是后者。
