无法在节点模块中找到响应本机提示

Question

我已经安装了react-native-prompt。我可以看到它已添加到package.json，但我在node_modules上找不到它 - react-native-prompt中没有node_modules目录。当我尝试导入react-native-prompt时，它表示undefined不是一个对象。这是我的代码：

import React from 'react';
import Prompt from 'react-native-prompt';

const AddTaskPrompt = ({isVisible,onCancelCallBack,onSubmitCallBack}) => (
<Prompt
    title="ajouter une tache"
    placeholder="ex: ramenre du lait"
    defaultValue=""
    visible={isVisible}
    onCancel={() => onCancelCallBack()}
    onSubmit={value => onSubmitCallBack(value)} />
);
export default AddTaskPrompt;

我的package.json的内容看起来像
