Error: Failed to upgrade Homebrew Portable Ruby!

执行brew search redis时候报错，看了一下报错

报错原因：portable-ruby-2.6.8_1.el_capitan.bottle.tar.gz 这个文件校验不匹配，Homebrew升级失败。

解决方案：可以看到提示让我们To retry an incomplete download, remove the file above.

删除上面这个portable-ruby-2.6.8_1.el_capitan.bottle.tar.gz文件。

rm -rf /Users/自己的用户名/Library/Caches/Homebrew/portable-ruby-2.6.8_1.el_capitan.bottle.tar.gz

删除后在去获取redis版本和下载就没问题了。
