Solution to “Ruby / San check”

Baidu one found that everyone is an article to turn around, as follows:
The root of the problem is the lack of a necessary C++ library. If it is a CentOS system, run the following command to resolve:

    yum install glibc-headers

    yum install gcc-c++ 

In Ubuntu, run the following command:

   apt-get install build-essential 
 
   apt-get install g++

I checked my GCC carefully and found that it was installed, not this problem. When executing YUM Update, I found this line:

So I tried it

yum install  kernel-headers

Problem solving.
