node.js - 开玩笑- map : @providesModule naming collision

Question

当我运行 npm start 或 react-native start 时，我收到了这个警告:

jest-haste-map: @providesModule naming collision:
  Duplicate module name: core-js
  Paths: {path_to_project}/node_modules/react-native/node_modules/core-js/package.json collides with {path_to_project}/node_modules/react-native/node_modules/fbjs/node_modules/core-js/package.json

This warning is caused by a @providesModule declaration with the same name across two different files.
jest-haste-map: @providesModule naming collision:
  Duplicate module name: base64-js
  Paths: {path_to_project}/node_modules/react-native/node_modules/base64-js/package.json collides with {path_to_project}/node_modules/react-native/node_modules/simple-plist/node_modules/base64-js/package.json

This warning is caused by a @providesModule declaration with the same name across two different files.

这是我的 package.json 文件

{
  "name": "ProjectName",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    "chroma-js": "^1.3.4",
    "crypto-js": "^3.1.9-1",
    "mobile-center": "^0.7.0",

    "react-native-vector-icons": "^4.2.0",
    "react-navigation": "^1.0.0-beta.11",
    "react-timer-mixin": "^0.13.3",
    "realm": "^1.10.0"
  },
  "devDependencies": {
    "babel-jest": "20.0.3",
    "babel-plugin-transform-decorators-legacy": "^1.3.4",
    "babel-preset-react-native": "2.0.0",
    "jest": "20.0.4",
    "react-test-renderer": "16.0.0-alpha.12"
  },
  "jest": {
    "preset": "react-native"
  }
}

我的开发环境是:

node: v6.11.2
npm: 3.10.10
os: macOS Sierra

我已经尝试过任何方法，例如更新RN版本，清除watchMan缓存，指定所有依赖项的版本，调整devDependencies的版本像babel-jest的版本，但都不起作用。我不知道出了什么问题，我需要帮助。或者这是否是一个问题。

任何事情都是感激的!

可能您生成了带有名称的项目，然后将 package.json 中的 name 属性更改为不同的名称。

检查 app.json 和 package.json 文件，看看您的应用程序的所有文件是否具有相同的项目名称
