无法解析模块`@expo/vector‘

Question

我不知道为什么我会犯这个错误：

Unable to resolve module `@expo/vector-icons` from `...(directory path here)...` : Module does not exist in the module pack

我在其他论坛/网站上尝试了以下建议：

1. 透明守望表
2. 删除node_modules文件夹
3. 复位包装机缓存

package.json

{
  "name": "app name",
  "version": "0.0.0",
  "description": "Hello Expo!",
  "author": null,
  "private": true,
  "main": "node_modules/expo/AppEntry.js",
  "dependencies": {
    "babel-plugin-module-resolver": "^2.5.0",
    "babel-preset-expo": "^4.0.0",
    "expo": "^21.0.0",
    "firebase": "^4.5.1",
    "geofire": "^4.1.2",
    "moment": "^2.19.1",
    "react": "16.0.0-alpha.12",
    "react-native": "https://github.com/expo/react-native/archive/sdk-21.0.2.tar.gz",
    "react-navigation": "^1.0.0-beta.13"
  }
}

但还是什么都没有，仍然有这个错误

Answer 1

听起来vector-icons是您应该在package.json (https://www.npmjs.com/package/@expo/vector-icons)中声明的另一个库。

Answer 2

我通过命令npm install @expo/vector-icons --save解决了这个问题

Answer 3

我遇到了同样的问题。这是巴贝尔预置博览会。卸载它，然后执行以下操作

npm i metro-react-native-babel-preset --save-dev

删除babel.config.json并创建一个名为.babelrc的新文件

然后指定预置

{
  "presets": ["module:metro-react-native-babel-preset"]
}
