Hi, thank you for sharing this high quality tutorial and I'm learning React Router with your example now. But when I do the fifth example, the console says Duplicate declaration "BasicRouting" and the page can not be running, did I do anything wrong? Here's my code hope you can take a look: https://jsfiddle.net/51jrub1s/

thanks again.

after use yarn run build , put it on server , it's render nothing , but good on local
here is my router config code

<Router basename="/novel-app">
            <div>
                <Route exact path='/' component={Index}/>
                <Route path='/Index' component={Index}/>
                <Route path='/searchResult' component={SearchResult}/>
                <Route path='/sources' component={Sources}/>
                <Route path='/categories' component={Categories}/>
                <Route path='/chapter' component={Chapter}/>
                <Route path='/cat' component={Cat}/>
            </div>
        </Router>

what should i do?
