React.createElement类型无效错误：循环生成组件触发，换默认导出仍未解决

Let's walk through the issues causing this error and fix them one by one:

1. Incorrect Component Import #

The first critical problem is your import of TouchableWithoutFeedbackComponent — this isn't a valid component in React Native. The correct component name is TouchableWithoutFeedback. When you try to use an undefined component (because the import is wrong), React throws that "type is invalid" warning since it expects a valid component type, not undefined.

2. Invalid JSX Render Syntax #

In your render method, you have this line:

{{ navigationItems }}

This wraps your navigationItems array in an extra set of curly braces, which creates a plain JavaScript object ({ navigationItems: navigationItems }). React can't render objects directly, so this will cause additional rendering issues. You only need one set of curly braces to embed the array into your JSX.

3. Verify Export/Import Matching #

You mentioned switching to export default but still seeing errors — make sure your import statement matches your export style:

• If using named export (export class TabWidgetComponent ...), import like this:

  import { TabWidgetComponent } from './path-to-your-component';
  

• If using default export (export default class TabWidgetComponent ...), import like this:

  import TabWidgetComponent from './path-to-your-component';
  

Corrected Full Code #

Here's the fixed version of your component with all the above changes:

import React from "react";
import {TabWidgetNamespace} from "shared/namespaces/tab-widget.namespaces";
import {StyleSheet, Text, TouchableWithoutFeedback, View} from "react-native";

export class TabWidgetComponent extends React.Component<TabWidgetNamespace.TabWidgetPropsInterface, TabWidgetNamespace.TabWidgetStateInterface>{
  style = StyleSheet.create({
    TabContainer: {
      overflow: 'hidden',
    },
    TabNavigation: { overflow: 'hidden' },
  })
  constructor(props: TabWidgetNamespace.TabWidgetPropsInterface) {
    super(props);
  }
  render(): React.ReactNode {
    const navigationItems = this.props.tabNavigation.map(
      (item, index) => (
        <TouchableWithoutFeedback key={index}>
          <Text>{item.label}</Text>
        </TouchableWithoutFeedback>
      )
    );
    return(
      <View style={this.style.TabContainer}>
        <View style={this.style.TabNavigation}>
          {navigationItems}
        </View>
      </View>
    );
  }
}

After making these changes, the error should disappear, and your tab navigation items should render correctly.
