错误： [未处理的承诺拒绝：错误：预期 URL 方案 'http' 或 'https' 但 'file']

我尝试在 react-native expo 项目上使用 pixi js。

这是 package.json 文件。

和app.json文件。

...

这是我的屏幕代码。

import React from 'react';
import { GLView } from 'expo-gl';
import ExpoPixi,{ PIXI } from 'expo-pixi';

export default class GameReady extends React.Component {
  render() {
    return (
      <GLView
        style={{ flex: 1 }}
        onContextCreate={async context => {
          const sprite = await PIXI.Sprite.fromExpoAsync('https://ubisafe.org/images/sans-transparent-8-bit.png');
          const app = new PIXI.Application({ context });
          app.stage.addChild(sprite);
        }}
      />
    );
  }
}

错误：
