我构建反应本机应用程序（版本0.49） . 我安装了mobx react和babel-plugin-transform-decorators-legacy来使用装饰器 . 然后，它向我展示了一些错误，它不能识别装饰器，所以进入jsconfig.json我添加
"compilerOptions": {
"allowJs": true,
"allowSyntheticDefaultImports": true,
"experimentalDecorators": true // I added this line
},
并且它没有显示错误但是当我想在我的组件中使用它并且我在@inject和@observer装饰器中使用时，你可以在示例中看到
@inject("userStore")
@observer
class UserDetails extends Component {
constructor(props){
super(props);
this.state = {
user:null
}
}
在@inject的行中引发了我的错误
unexpected token
那是我的package.json

将它添加到
jsconfig.json是不够的 .安装这些依赖项：
.babelrc文件告诉babel编译器要做什么，而不是jsconfig.json. 所以创建.babelrc文件并添加以下内容：
