React本机导入React导航

Question

我遵循Android安装React导航的所有说明。

首先，“npm安装--Save React-Navigation”，“npm安装--Save React-Native-Gesture-Handler”。“react-native link react-native-gesture-handler”，最后，更新了我的mainactivity.java

import com.facebook.react.ReactActivity;
import com.facebook.react.ReactActivityDelegate;
import com.facebook.react.ReactRootView;
import com.swmansion.gesturehandler.react.RNGestureHandlerEnabledRootView;

public class MainActivity extends ReactActivity {

/**
 * Returns the name of the main component registered from JavaScript.
 * This is used to schedule rendering of the component.
 */
@Override
protected String getMainComponentName() {
    return "InstagramClone";
}

@Override
protected ReactActivityDelegate createReactActivityDelegate() {
return new ReactActivityDelegate(this, getMainComponentName()) {
  @Override
  protected ReactRootView createRootView() {
   return new RNGestureHandlerEnabledRootView(MainActivity.this)
  }
};
}
}

这是我得到的错误：

• 错误所在：在创建目录'd:\react Native projects\instagramclone\node_modules\react Native projects\instagramclone\node_modules\react-Native-genture-handler\android\build\mediverates\check-manifest\debug'
时，未能创建父目录'd:\react Native projects\instagramclone\node_modules\react Native

如果您使用expo启动项目，只需安装react-native-gesture-handler。但是，如果您的计划是由react-native CLI启动的，则必须首先安装react-native-gesture-handler，然后通过以下命令将其链接到所有包：

react-native link
