我正在尝试理解反应导航,我正在设置一个概念应用程序来理解.

我最初在努力的是,我得到错误信息"路由的组件"SomeRoute"必须是一个React组件"

我知道,这意味着什么,但我不明白为什么会抛出这个错误.

我有以下设置:

App.js:

import React from 'react';
import { Root } from './config/router';
import { SafeArea } from 'react-native';
class App extends Component {
    render() {
        return <Root />;
    }
}
export default App;

router.js(config/router.js)

import React from 'react';
import { DrawerNavigator, TabNavigator, StackNavigator } from 'react-navigation';

import Feed from './../components/Feed';
import Search from './../components/Search';
import Favorites from './../components/Favorites';

import TextList from './../components/ComingSoon';
import Detail from './../components/Detail';
import Downloads from './../components/Downloads';

export const FeedStack = StackNavigator({

    Feed: { …

我最近升级了 react-native 版本

react-native upgrade

并遵循所有步骤，到目前为止没有任何错误。现在，当我想构建 ios 版本时，出现以下错误：

?  ld: symbol(s) not found for architecture x86_64
?  clang: error: linker command failed with exit code 1 (use -v to see invocation)

** 构建失败 **

以下构建命令失败：

Ld build/Build/Products/Debug-iphonesimulator/CustomName.app/CustomName normal x86_64

(1 次失败)

The following commands produced analyzer issues:
Analyze Base/RCTModuleMethod.mm normal x86_64
Analyze RCTNetInfo.m normal x86_64
Analyze RCTImageCache.m normal x86_64
(3 commands with analyzer issues)
