Question

首次尝试：

const webViewScript = `
  setTimeout(function() { 
    window.postMessage(document.documentElement.scrollHeight); 
  }, 500);
  true; // note: this is required, or you'll sometimes get silent failures
`;


...
constructor(props) {
    super(props);
    this.state = {
      webheight:100,
    }

...

<WebView style={{height: this.state.webheight}}
  automaticallyAdjustContentInsets={false}
  scrollEnabled={false}
  source={{uri: "http://<your url>"}}
  onMessage={event => {
    this.setState({webheight: parseInt(event.nativeEvent.data)});
  }}
  javaScriptEnabled={true}
  injectedJavaScript ={webViewScript}
  domStorageEnabled={true}
></WebView>

我尝试安装它

c++: not found

但未成功

第三次尝试，我尝试过：
```
sudo apt install c++
```
然后我又收到有关c ++的错误

请问我做错了什么？谢谢

错误：

pip2 install --user phoebe
