gem install redis-dump 安装失败

Building native extensions. This could take a while...
ERROR: Error installing redis-dump:

找了好久没发现是哪里出了问题，之前一直按照ERROR: Error installing redis-dump:
ERROR: Failed to build gem native extension.来检索的，试了好多种方法没效果。后来无意间看见gcc那行，才发现可能是make、gcc未安装(脑海里一直以为gcc以前安装过)。

键入sudo apt install build-essential   该命令将安装一堆新包，包括gcc，g ++和make。

再次尝试gem install redis-dump
