brickspert / react-family Goto Github PK

页面切换的时候会出现这个警告 不太清楚这个警告是由于什么原因导致的
Warning: forceUpdate(...): Can only update a mounted or mounting component. This usually means you called forceUpdate() on an unmounted component. This is a no-op. Please check the code for the UserInfo component.

路由报错 切换到react-redux 4.x版本依然报错；大神帮忙看看

\react-family\src\redux>node build

报错： Unexpected token import

只修改webpack 的output 的publicPath = ‘/’ 改为 './'来放在 github上加载

在安装 babel-preset-es2015 时，注意到现在推荐使用 babel-preset-env。

npm WARN deprecated [email protected]: 🙌 Thanks for using Babel: we recommend using babel-preset-env now: please read babeljs.io/env to update!

于是就了解了一下 babel-preset-env，它可以根据运行环境智能的转换代码，而不是一股脑的转换成 ES5，更能充分的发挥新版本的特性。是否考虑使用 babel-preset-env 替换大堆预设？

请教您一个问题，就是 react-router 4.0 + 可以实现嵌套路由吗，网上的资料确实有限，目前还没发现一个标准答案，嘿嘿。

用最新版的webpack 和webpack-dev-server，在webpack-dev-server服务器运行时会报错。后来看了package.json改了版本。。在安装的时候指定版本会不会好点.

博主，我想请教一下这个工程的部署方式，我直接点击index.html打开浏览器一片空白。
