无法在本机应用程序中使用 Ionicons

Question

我正在尝试使用 expo 在 react-native 应用程序上使用 Ionicons，不幸的是图标没有显示并且收到以下错误：

fontFamily "ionicons" is not a system font and has not been loaded through Font.loadAsync.

If you intended to use a system font, make sure you typed the name correctly and that it is supported by your device operating system.

If this is a custom font, be sure to load it with Font.loadAsync.

我通过以下方式使用 Iocincons：

import { Ionicons }  from '@expo/vector-icons';

....

<Ionicons name="arrow-back" size={24} color="black" />

此外，这是我的 package.json 文件：

{
  "main": "node_modules/expo/AppEntry.js",
  "scripts": {
    "start": "expo start",
    "android": "expo start --android",
    "ios": "expo start --ios",
    "web": "expo start --web",
    "eject": "expo eject"
  },
  "dependencies": {
    "@expo/vector-icons": "^12.0.4",
    "@react-native-community/masked-view": "^0.1.10",
    "axios": "^0.21.1",
    "expo": "~40.0.0",
    "expo-app-loading": "^1.0.1",
    "expo-font": "^9.0.0",
    "expo-status-bar": "~1.0.3",
    "react": "16.13.1",
    "react-dom": "16.13.1",
    "react-native": "https://github.com/expo/react-native/archive/sdk-40.0.1.tar.gz",
    "react-native-gesture-handler": "^1.10.3",
    "react-native-reanimated": "^2.0.1",
    "react-native-screens": "^2.18.1",
    "react-native-web": "~0.13.12",
    "react-navigation": "^4.4.4",
    "react-navigation-header-buttons": "^7.0.0",
    "react-navigation-stack": "^2.10.4",
    "react-redux": "^7.2.3",
    "redux": "^4.0.5"
  },
  "devDependencies": {
    "@babel/core": "^7.13.15"
  },
  "private": true
}

我已经尝试删除 node_modules、package-lock.json 和运行 npm install，但没有解决问题。

任何想法将不胜感激。
