Question

现在，我正在尝试使应用程序在本机和博览会中做出反应。昨天我没事，但今天当我开始做世博会时，却遇到了这个错误。

TypeError：未定义不是对象（正在评估'this._callListeners.bind'）

我认为这个问题是基于反应导航，博览会或其他版本的。

这是我下面的package.json

"dependencies": {
    "@expo/vector-icons": "^9.0.0",
    "expo": "^32.0.0",
    "expo-cli": "^2.11.9",
    "firebase": "^4.12.1",

    },

我的应用没有明显原因开始显示此错误后，我花了数小时在google上搜索此问题的解决方案，但没有任何效果。最后，我尝试做expo start -c，因为我记得Expo v33 upgrade documentation中提到的内容。我的错误消失了。

如何解决本机应用程序中的此错误？
