问题描述

现在我正在尝试制作一个反应原生和博览会的应用程序。昨天,我很好,但今天当我开始世博会时,我得到了这个错误。

类型错误:未定义不是对象(评估“this._callListeners.bind”)

我认为这个问题是基于 react-navigation、expo 或其他版本。

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",
    "mobx": "^5.8.0",
    "mobx-react": "^5.4.3",
    "react": "16.5.0",
    "react-native": "https://github.com/expo/react-native/archive/sdk-32.0.0.tar.gz",
    "react-native-maps": "^0.23.0",
    "react-native-modal": "^7.0.2",
    "react-native-vector-icons": "^6.1.0",
    "react-navigation": "^3.4.1"
    },
     "devDependencies": {
    "@babel/plugin-proposal-class-properties": "^7.3.4",
    "@babel/plugin-proposal-decorators": "^7.3.0",
    "@babel/preset-react": "^7.0.0",
    "babel-eslint": "^10.0.1",
    "babel-plugin-transform-decorators-legacy": "^1.3.5",
    "babel-preset-expo": "^5.0.0",
    "babel-preset-mobx": "^2.0.0",
    "babel-preset-react-native": "^4.0.1",
    "directory": "^0.1.0",
    "eslint": "^5.12.0",
    "eslint-config-airbnb": "^17.1.0",
    "eslint-plugin-import": "^2.14.0",
    "eslint-plugin-jsx-a11y": "^6.1.2",
    "eslint-plugin-react": "^7.12.3",
    "metro-react-native-babel-preset": "^0.53.0"
},

解决方案


在我的应用程序无缘无故开始显示此错误后,我花了几个小时在谷歌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,因为我记得在Expo v33 升级文档中提到过。我的错误消失了。
