On Error not type does Property exist home

问题描述：
我在react中用typescript时，定义一个Home组件，然后在组件里用setState时会有这样一个报错：（如图）Property 'setState' does not exist on type 'Home'
分析解决：
报错说我的Home组件上不存在setState属性，但是我把文件的后缀名从‘.tsx’改成‘.jsx’就不报这个错了，推断是typescript的类型检查报的这个错，识别不了react组件就不认为这个class函数上有setState属性。安装一下react、react-dom的类型定义就解决啦
npm install --save-dev "@types/react" "@types/react-dom"
