??在安装grpcio的依赖的时候，竟然发现了编译失败，网上找了一大圈的，都解决不了我的问题，比如下载python-devel依赖，比如升级pip等等，最后发现原来换个方式搜就能解决问题了。
报错：

解决
??首先要明白pip在拉依赖包的时候，默认会拉wheel包，即已经是编译好的包，那如果wheel都能拉到，自然就无须编译了。我在centos7上就默认拉到了grpcio-1.41.0-xx.whl，而在另一套alpine环境下，就出现上述的gcc compile error。
??明白上述的问题后，实际上就是解决两个问题：1.如何拉到wheel包；2.拉不到wheel包，如何解决编译异常
??针对第一个问题，我们可以登录grpcio的官网：https://pypi.org/project/grpcio/1.41.0/#files，查所需的linux系统的依赖包，很遗憾，没找到常用的cp36-linux包，所以官网未提供；那我们可以想办法去打造，于是我在centos7系统上根据官网tar.gz包解压后的setup.py去生成一个wheel包（命令：python setup.py bdist_wheel），发现仍旧是编译失败，于是第一条彻底失败；
??而当我搜了第二条一圈都搜不到答案时，换了一种方式搜，就搜到了，关键词：alpine grpcio gcc compile error就ok。解决方案：https://blog.csdn.net/q1026378552/article/details/111610171
。即安装两个依赖即可：
apk add build-base linux-headers
