不变违规：requireNativeComponent：“BVLinearGradient”

Question

我一直在使用react-native-gradient，但我收到以下关于包的错误。

错误

Invariant Violation: requireNativeComponent: "BVLinearGradient" was not found in the UIManager.

This error is located at:

用法

...
import * as Animatable from "react-native-animatable";
import LinearGradient from "react-native-linear-gradient";
import MaterialIcons from "react-native-vector-icons/MaterialIcons";
import { useTheme } from "@react-navigation/native";


const SignupLogin = ({ navigation }) => {
  const { colors } = useTheme();
  return (
    <View style={styles.container}>
      .....
        <View style={styles.button}>
          <TouchableOpacity onPress={() => navigation.navigate("sign-in")}>
            <LinearGradient
              colors={["#0831d4", "#0131ab"]}
              style={styles.signIn}
            >
              <Text style={styles.textSign}>Get started</Text>
              <MaterialIcons name="navigate-next" color="#fff" size={20} />
            </LinearGradient>
         .....
    </View>
  );
};


export default SignupLogin;

在页脚登录和注册菜单之间进行简单导航，App.js 和其余文件采用标准编码方法。

确认安装react-native-linear-gradient

yarn add react-native-linear-gradient

在ios中确认ios/podfile有这行

pod 'BVLinearGradient', :path => '../node_modules/react-native-linear-gradient'

然后在ios文件夹中运行pod install
