android - 错误 : jest-haste-map: Haste module naming collision:

Question

我已经创建了一个自定义的 npm 模块(将使用 xxx 而不是它的名称)并使用 npm install 手动链接它。

我非常努力地搜索:

• [Workarounds] Packager unable to resolve module from /Users/node_modules/
• Error: jest-haste-map: @providesModule naming collision when using a local dependency

在提出问题之前。如果有人告诉我我的代码或我的方法有什么问题或我的代码中有任何错误，我将不胜感激。

当我运行 react-native run-android 时，metro bundler 引发了以下错误

Error: jest-haste-map: Haste module naming collision:
  Duplicate module name: react-native
  Paths: E:\cdg-native\CDG\node_modules\react-native-XXX\node_modules\react-native\package.json collides with E:\cdg-native\CDG\node_modules\react-native\package.json

This error is caused by `hasteImpl` returning the same name for different files.

我的自定义模块 package.json 是

{
  "name": "react-native-xxx",
  "version": "1.0.0",
  "description": "Library to render xxx",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [
    "react native xxx"
  ],
  "author": "Firdous Nath",
  "license": "ISC",
  "peerDependencies": {
    "react": "*",
    "react-native": "*"
  },
  "devDependencies": {
    "react": "^16.6.1",
    "react-native": "^0.57.5",
    "babel-cli": "^6.26.0",
    "babel-plugin-transform-class-properties": "^6.24.1",
    "babel-plugin-transform-object-rest-spread": "^6.26.0",
    "babel-plugin-transform-runtime": "^6.23.0",
    "babel-preset-env": "^1.6.1",
    "babel-preset-react": "^6.24.1"
  }
}

自定义模块的

index.js非常简单如下

import React from "react";
import { Text } from "react-native";

export default class XXXView extends React.Component {

    render() {
        return (
            <Text> From custom module </Text>
        );
    }
}

我使用自定义模块的文件是

import React from "react";
import {StyleSheet, View} from "react-native";
import XXXView from "react-native-xxx"
//import {XXXView} from "react-native-xxx" -> I tried this as well

export default class App extends React.Component {
    render() {
        return (
            <View style={styles.container}>
                <XXXView/>
            </View>
        )
    }
}

const styles = StyleSheet.create({
    container: {
        flex: 1,
        justifyContent: "center",
        alignItems: "center",
        backgroundColor: "#f5fcff"
    }
});

我尝试了 npm install/absolute/path/to/xxx 并且它正确地链接了模块。正确地说，我的意思是我可以在 nodemodule 目录中看到 react-native-xxx 包。 我尝试了所有可能的方法，但没有任何效果。

我也试过，但没有成功

• yarn 添加/absolute/path/to/react-native-xxx
• react-native 链接 react-native-xxx
• react-native run-android

在根项目中添加rn-cli.config.js

const blacklist = require('metro-config/src/defaults/blacklist');
module.exports = {
 resolver: {
    blacklistRE: blacklist([
        /node_modules\/.*\/node_modules\/react-native\/.*/,
    ])
 },
};
