省略.tsx后缀

当tsconfig.json配置了，需要重启后才会生效

 {"compilerOptions": {"allowJs": true,"jsx": "react-jsx",}
}

当进行以上配置后，导入组件时添加后缀，Eslint报错如下：

An import path can only end with a ‘.tsx’ extension when ‘allowImportingTsExtensions’ is enabled

import Demo1 from './pages/demo/index.tsx';

改成以下即可

import Demo1 from './pages/demo/index';
