Expo Android Emulator customFonts无法正常工作 Expo Web Emulator正在运行

如何解决Expo Android Emulator customFonts无法正常工作 Expo Web Emulator正在运行

我不知道发生了什么。我的customFonts已经工作了几个星期。它们仍适用于Expo Web版本。但是现在在Android模拟器中，我收到此错误消息：

fontFamily "proxima-nova-bold" 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.
* [native code]:null in __expoConsoleLog
...

这是我在前端的代码：

import * as Font from "expo-font";
import { AppLoading } from "expo";

let customFonts = {
  "proxima-nova-thin": require("./app/assets/fonts/proxima-nova-thin.ttf"),"proxima-nova-normal": require("./app/assets/fonts/proxima-nova-normal.ttf"),"proxima-nova-bold": require("./app/assets/fonts/proxima-nova-bold.ttf"),"proxima-nova-extrabold": require("./app/assets/fonts/proxima-nova-extrabold.ttf"),"proxima-nova-black": require("./app/assets/fonts/proxima-nova-black.ttf"),"times-new-roman": require("./app/assets/fonts/times-new-roman.ttf"),};

class App extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      page: "LoginorSignUp",email: "",code: 572987,fontsLoaded: false,};
  }

  async _loadFontsAsync() {
    await Font.loadAsync(customFonts);
    this.setState({ fontsLoaded: true });
  }
  componentDidMount() {
    this._loadFontsAsync();
  }

...

  render() {
    if (this.state.fontsLoaded) {
      return (...

有人知道如何解决此问题吗？
