错误1：
如果linux环境中，缺少g++，则会报错：
解决办法：
安装g++ (或者下面这个，替代g++的) yum install gcc-c++

错误2：
直接使用pip install ，会报错：
cc1plus: warning: command line option "-Wstrict-prototypes" is valid for Ada/C/ObjC but not for C++ snappymodule.cc:31:22: error: snappy-c.h: No such file or directory snappymodule.cc:77: error: 'snappy_status' was not declared in this scope snappymodule.cc:78: error: expected ',' or ';' before '{' token snappymodule.cc:45: warning: '_state' defined but not used snappymodule.cc:56: warning: 'SnappyCompressError' defined but not used snappymodule.cc:57: warning: 'SnappyUncompressError' defined but not used snappymodule.cc:58: warning: 'SnappyInvalidCompressedInputError' defined but not used snappymodule.cc:59: warning: 'SnappyCompressedLengthError' defined but not used snappymodule.cc:77: warning: 'snappy_strerror' defined but not used error: command 'gcc' failed with exit status 1
报错根源是找不到关键文件： snappy-c.h
解决办法：
最简便的解决办法是，先装一下 snappy-devel
yum install snappy-devel
然后再装 python-snappy，就没有问题了
pip install python-snappy
