滿滿的干貨。謝謝老師，好期待老師再出一個react + redux的課程 O(∩_∩)O。路由顯示一直報錯不知道怎么解決，頁面顯示錯誤：TypeError: Cannot read property 'location' of undefined；控制臺顯示：main.js:826 Warning: Failed prop type: The prop `history` is marked as required in `Router`, but its value is `undefined`. 裝的是"react-router": "^2.0.0"。有遇到的小伙伴嗎？大家怎么解決的呢？
