ant-design-pro IE9下報錯集合

1.下載下來eslint報錯：Expected linebreaks to be ‘LF’ but found ‘CRLF’
解決方法：新增或修改linebreak-style為 ["error", "windows"]，即
rules: { 'linebreak-style': ["error", "windows"], },
2.IE9下佈局錯亂如下圖：

解決方法：
<!-[if IE 9]> <style> .ant-layout-has-sider > .ant-layout-sider { float: left; position: relative; height: 100% !important; } </style> <![endif]-->

3. 無法獲取未定義或 null 引用的屬性“authority”或者The Intl APIs must be available in the runtime, and do not appear to be built-in. An Intl polyfill should be loaded.或者requestAnimationFrame not defined
   第一步：
   $ npm install --save intl @babel-polyfill
   第二步，在src下新建一個global.js檔案，新增如下程式碼
   import '@babel/polyfill'; global.requestAnimationFrame = function(callback) { setTimeout(callback, 0); }; global.cancelAnimationFrame= function(callback) { setTimeout(callback, 0); }; global.Intl = require('intl'); window.Intl = require('intl');
