使用了react-native link，还有这个问题。

guys I just got it running by re-add libRCTBEEPickerManager.a at link binary with libraries in xcode, if re-add doesn't work please run react-native link again

@TristanLudrow solution also works for me. For me it usually happens when running on Android.

如果你 使用了react-native link 还报错，是因为 MainApplication.java 这个文件里面没有引入原生库 import com.beefe.picker.PickerViewPackage; getPackages()方法里面 new PickerPackage()

完整版 `import android.app.Application;

import com.facebook.react.ReactApplication; import com.beefe.picker.PickerViewPackage; import com.reactnative.ivpusic.imagepicker.PickerPackage; import com.facebook.react.ReactNativeHost; import com.facebook.react.ReactPackage; import com.facebook.react.shell.MainReactPackage; import com.facebook.soloader.SoLoader;

import java.util.Arrays; import java.util.List;

public class MainApplication extends Application implements ReactApplication {

private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) { @Override public boolean getUseDeveloperSupport() { return BuildConfig.DEBUG; }

@Override
protected List<ReactPackage> getPackages() {
  return Arrays.<ReactPackage>asList(
      new MainReactPackage(),
      new PickerViewPackage(),
      new PickerPackage()
       
  );
}

};

@Override public ReactNativeHost getReactNativeHost() { return mReactNativeHost; }

@Override public void onCreate() { super.onCreate(); SoLoader.init(this, /* native exopackage */ false); } } `

使用了react-native link 还报错，IOS

[ZKeLin]

一样的错误，怎么解决啊？？？？？？？？？？？？ android没问题，ios有问题，报undefined is not an object(evaluating 'Picker._init')错误

[ranyunlong]

上面的代码写的很详细

[BeyWood]

I fixed it

[MaybeSomeone]

如果已经react-native link 过的话，我建议将静态库删除，手动添加进入！ 我是通过这种方式解决的！

[ihewro]

sudo react-native link

如果你 使用了react-native link 还报错，是因为 MainApplication.java 这个文件里面没有引入原生库 import com.beefe.picker.PickerViewPackage; getPackages()方法里面 new PickerPackage() 用了这个方法 但是 还是报undefined is not an object (evaluating 'Picker._init')
