React Native - Get an error when using a custom component that I made (Error: undefined Unable to resolve module <MyModule>)

Question

我制作了一个名为 "react-native-weekly-calendar" 的自定义组件，我正在尝试将其发布到开源社区，但我想先测试一下。当我尝试通过 npm install --save ../<component_name> 对其进行测试时，它会抛出一个错误。

我的目录结构：

- react-native-weekly-calendar (folder)
    - index.js
    - package.json
    - src (folder)
        - Locale.js
        - Style.js

index.js:

import React, { useState, useEffect, useRef } from 'react';
import { Text, View, ScrollView, TouchableOpacity, TouchableWithoutFeedback, Modal, Platform, ActivityIndicator } from 'react-native';
import PropTypes from 'prop-types';
import moment from 'moment/min/moment-with-locales';
import DateTimePicker from '@react-native-community/datetimepicker';
import { FontAwesome } from 'react-native-vector-icons';
import { applyLocale, displayTitleByLocale } from './src/Locale';
import styles from './src/Style';

const WeeklyCalendar = props => {
    ...
}

export default WeeklyCalendar;

package.json:

{
  "name": "react-native-weekly-calendar",
  "version": "0.1.0",
  "description": "Weekly Calendar component for React Native",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "repository": {
    "type": "git",
    "url": "git+https://github.com/codeinjuice/react-native-weekly-calendar.git"
  },
  "keywords": [

    "datepicker",
    "date-picker"
  ],

  "dependencies": {
    "moment": "^2.24.0",
    "prop-types": "^15.5.7",
    "@react-native-community/datetimepicker": "~2.1.0",
    "react-native-vector-icons": "~6.6.0"
  },
  "devDependencies": {
    "@babel/core": "^7.0.0",
    "metro-react-native-babel-preset": "^0.58.0",
    "react": "~16.9.0",
    "react-native": "0.61.4"
  }
}

以下是我使用上述文件进行测试的方式：

$ npx react-native init sample
$ cd sample
$ npm install --save ../react-native-weekly-calendar
$ vim App.js

然后我在App.js中添加了import WeeklyCalendar from 'react-native-weekly-calendar';。最后我运行

$ npx react-native run-ios

在模拟器中，我得到这个错误：

Unable to resolve module 'react-native-weekly-calendar' from 'App.js':react-native-weekly-calendar could not be found within the project.

我是不是在 package.json 中设置了错误的依赖设置？？？

我不明白为什么它明明在 node_modules 文件夹中却一直说找不到该组件。

欢迎提出任何建议！

编辑：我将 react-native 从 0.60.* 升级到 0.61.4，它也适用于 npm。

原回答 我用了 $ yarn add ../react-native-weekly-calendar

而不是 $ npm install --save ../react-native-weekly-calendar 并且有效。
