【问题描述】：
我目前面临一个问题，在运行expo start 时，一旦在 ios 模拟器和设备上完成加载（Android 尚未测试），应用程序会显示白色空白屏幕。
我最初在 react-native CLI 上启动了这个项目，最近迁移到 Expo。这个问题在迁移后就很明显了。
我已经按照网上的一些说明来尝试解决这个问题，但是我没有运气。在 VSC 中运行 JS Debug 时控制台没有错误，也没有问题
请在下面找到我的 package.json 文件

【问题讨论】：
-
你试过 npm install 了吗？
-
嗨，是的 - 但是它没有解决问题
-
你能发布你的 app.js
-
您使用的是托管工作流还是裸工作流？
