我刚用这个命令安装了
React Native vector icons：
npm install react-native-vector-icons
但是如果我在index.android.js中使用它
<Icon name="ios-add" size={30} color="#4F8EF7" />
我得到一个正方形,中间有一个X而不是图标.
为什么？
编辑：
如果我尝试使用“npm install react-native-vector-icons –save”安装它,那么我收到此错误：

我已经从物理设备中删除了应用程序,然后我重新构建它(正如QMFNP所说).现在它有效
首先,确保通过执行以下操作来保存项目中的依赖项：
原文链接：https://www.f2er.com/react/300882.htmlnpm install react-native-vector-icons –save.包括–save是必要的,否则react-native链接将无法定位模块.
在iOS或Android项目中使用它们之前,还必须链接本机模块.快速执行此操作的方法是使用以下命令：
react-native链接react-native-vector-icons
如果由于任何原因您在使用react-native链接链接本机模块时遇到问题,react-native-vector-icons README还提供了在Android和iOS上手动链接它们以及在Web上集成库的详细说明.
