问题描述
我当前遇到一个问题，当运行expo start时，一旦在ios模拟器和设备上完成加载（未对Android进行测试），该应用程序就会显示白色的空白屏幕。
我最初在本机CLI上启动了这个项目，最近又迁移到了Expo。自迁移以来，这个问题就很明显了。
我已经按照网上的许多说明尝试尝试解决此问题，但是我没有运气。在VSC中运行JS调试时，控制台中没有错误，也没有问题
请在下面找到我的package.json文件

提前谢谢
解决方法
为了防止某个可怜的灵魂与我处于类似的情况，我通过在 package.json 中添加 "main": "node_modules/expo/AppEntry.js" 来解决它。事实证明，当我从非博览会项目迁移到博览会项目时，它已被删除。
