yarn install 安装报错问题

   前言：今天使用 wb 新建 react 项目时，出现如下问题：

   提示说明：与 yarn 有关。且与淘宝镜像有关，具体问题报告（log）如下：

原因：主要是 yarn 的淘宝镜像问题。

解决：

网上查找解决方法如下：

执行以下命令：
1. yarn config set registry https://registry.npm.taobao.org/
2. rm -rf /node_modules
3. yarn install --no-bin-links
确认没有错误再往下执行，不然就还得排查错误。

另外，有时候 rm -rf node_modules，重新 yarn install 就可以解决问题，祝好运。

由于博主使用的是 windows 系统，只执行命令1，如下：

yarn config set registry https://registry.npm.taobao.org/

只执行了这句命令，再次创建就成功了。
