【React】怎么暴露webpack配置规则？_react-scripts 暴露出来

暴露webpack配置规则的步聚如下

1. 在根目录下运行终端命令：yarn eject或npm run eject修改webpack默认配置，保险起见先执行命令：git add -A //添加到缓存区，git commit -m'init' //保存到历史区，再执行：yarn eject。

2. 终端命令：yarn eject的执行情况：
   会发生一些错误，因为之前我把代码给改了，所以在暴露之前我们先把代码提交到git历史区保留下来（这个操作是防止暴露后的代码覆盖了我们自己的代码）。
   注意：有这个错误提示的前提是（1）本地有git仓库。（2）代码在暴露之前有修改过代码。
