yarn install 安裝報錯問題

   前言：今天使用 wb 新建 react 項目時，出現如下問題：

   

   提示說明：與 yarn 有關。且與淘寶鏡像有關，具體問題報告（log）如下：

vagrant@homestead:~/Code/larabbs$ yarn config set registry https://registry.npm. taobao.org
yarn config v0.27.5

原因：主要是 yarn 的淘寶鏡像問題。

解決：

網上查找解決方法如下：

執行以下命令：
1. yarn config set registry https://registry.npm.taobao.org/
2. rm -rf /node_modules
3. yarn install --no-bin-links
確認沒有錯誤再往下執行，不然就還得排查錯誤。

另外，有時候 rm -rf node_modules，重新 yarn install 就可以解決問題，祝好運。

由於博主使用的是 windows 系統，只執行命令1，如下：

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

只執行了這句命令，再次創建就成功了。
