我已经使用expo开发了一个移动应用程序。在开发模式下一切正常。当我切换到生产模式时，出现错误“找不到变量a”，并且我不知道如何找到它，因为错误没有提示，正如您从以下link的图像中看到的那样
这是我的app.json：
"expo": {
"name": "my-app-name",
"slug": "my-app-slug",
"privacy": "public",
"sdkVersion": "32.0.0",
"platforms": [
"ios",
"android"
],
"version": "1.0.0",
"orientation": "portrait",
"icon": "./assets/icon.png",
"splash": {
"image": "./assets/splash.png",
"resizeMode": "contain",
"backgroundColor": "#ffffff"
},
"updates": {
"fallbackToCacheTimeout": 0
},
"assetBundlePatterns": [
"**/*"
],
"ios": {
"supportsTablet": true,
"bundleIdentifier": "my-bundle-identifier"
},
"android": {
"package": "my-bundle-identifier"
},
"description": ""
}
这是我的package.json：
{

}
当前，我已经使用expo设置了另一个项目，并且我正试图复制错误，一个接一个地添加库，以查看问题是否出在添加的库或代码中。
您能提出解决这个问题的更明智的方法吗？
