在安装新包时遇到问题

Question

我使用react-native-base来使用react-native组件。 我之前已安装

react-native-document-picker react-native-fcm react-native-image-crop-picker react-native-vector-icons react-navigation

但现在，无论我在现有应用程序中安装的新软件包/库，我的一些现有软件包/文件都将被删除，因此会出现很多错误。为什么在安装任何新软件包时会发生这种情况。 这是我在安装新库时附加的屏幕截图

的package.json

    "start": "node node_modules/react-native/local-cli/cli.js start",
