我正在尝试将基本模式(documented here)合并到现有的React组件中。 如果没有模态,则按钮呈现良好。
class NewInstanceModal extends React.Component<{}, {}> {
render() {
console.log('modal render');
return (<Button>Basic Modal</Button>);
}
}
当我按语义UI反应文档中所示添加模态组件时,它可以正常编译(打字稿),但在运行时会引发错误。
代码:
class NewInstanceModal extends React.Component<{}, {}> {
render() {
console.log('modal render');
return (
<Modal trigger={<Button>Basic Modal</Button>} basic size='small'>
<Header icon='archive' content='Archive Old Messages' />
<Modal.Content>
<p>Your inbox is getting full, would you like us to enable automatic archiving of old messages?</p>
</Modal.Content>
<Modal.Actions>
<Button basic color='red' inverted>
<Icon name='remove' />No
</Button>
<Button color='green' inverted>
<Icon name='checkmark' />Yes
</Button>
</Modal.Actions>
</Modal>
);
}
}
错误:
Invariant Violation: Portal.render(): A valid React element (or null) must be returned. You may have returned undefined, an array or some other invalid object.
此组件在另一个组件中呈现。我正在使用打字稿版本2.5,semantic-ui-react 0.82.0,semantic-ui-css 2.3.3。

我通过将React更新到最新版本16.4.2修复了该错误
