1、输入yarn后，下载失败报错

2、检查淘宝镜像 yarn config list

3、设置淘宝镜像  yarn config set registry https://registry.npmmirror.com/

yarn config set registry https://registry.npmmirror.com/

4、yarn install还是失败

 5、取消SSL连接：yarn config set strict-ssl false

6、yarn 下载到一半还是失败

7、重新设置淘宝镜像  npm config set registry http://registry.npmjs.org（这一步应该没用。。。）

8、yarn  下载成功
