无法加载捆绑包...需要Babel“ ^ 7.0.0-0”，但已加载“ 6.26.3”

Question

我正在尝试在我的应用中设置Expo的BarCodeScanner。 -https://www.npmjs.com/package/expo-barcode-scanner

我遇到了多个错误，这些错误似乎可以通过使用以下方式解决：

npm我的展览许可

npm我babel-preset-expo

{ "name": "empty-project-template", "private": true, "scripts": { "start": "react-native start", "android": "react-native run-android", "ios": "react-native run-ios" }, "dependencies": { "@babel/runtime": "^7.2.0", "babel-jest": "^23.6.0", "babel-preset-expo": "^5.0.0", "blinkid-react-native": "^4.5.0", "expo-barcode-scanner": "^1.1.0", "expo-permissions": "^1.0.2", "expo-react-native-adapter": "^1.0.2", "firebase": "^5.5.4", "native-base": "^2.8.1", "react": "16.3.1", "react-native": "^0.55.4", "react-native-credit-card-input": "^0.4.1", "react-native-date-picker": "^2.2.1", "react-native-datepicker": "^1.7.2", "react-native-elements": "^0.19.1", "react-native-image-crop-picker": "^0.21.2", "react-native-image-picker": "^0.27.2", "react-native-maps": "^0.22.1", "react-native-modal-datetime-picker": "^6.0.0", "react-native-photo-upload": "^1.3.0", "react-native-super-grid": "^2.4.3", "react-native-vector-icons": "^6.1.0", "react-navigation": "^2.18.0" }, "devDependencies": { "@babel/core": "^7.2.2", "babel-core": "^7.0.0-0", "babel-loader": "^8.0.4", "babel-preset-react-native-stage-0": "^1.0.1" } }

现在，出于测试原因，我已经复制并粘贴了Expo提供的一些示例代码。
