centos7.5 解决缺少libstdc++.so.6库的原因及解决办法

执行node -v报错如下：

[root@bogon ~]# node -v

node: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

先加载所有安装包

yum repolist

查看哪个安装包包含该库：

yum provides libstdc++.so.6

执行结果：

[root@bogon ~]# yum whatprovides libstdc++.so.6

Loaded plugins: fastestmirror

Loading mirror speeds from cached hostfile

 * base: mirrors.njupt.edu.cn

 * extras: mirrors.163.com

 * updates: mirrors.njupt.edu.cn

libstdc++-4.8.5-36.el7.i686 : GNU Standard C++ Library

Repo        : base

Matched from:

Provides    : libstdc++.so.6

可以看到安装包 libstdc++-4.8.5-36.el7.i686

安装libstdc++-4.8.5-36.el7.i686

yum -y install libstdc++-4.8.5-28.el7.x86_64

报错：

       ...you can also use --setopt=protected_multilib=false to remove

       this checking, however this is almost never the correct thing to

       do as something else is very likely to go wrong (often causing

       much more problems).

       Protected multilib versions: libstdc++-4.8.5-36.el7.i686 != libstdc++-4.8.5-28.el7.x86_64

解决办法：

1、升级安装包

yum  update libstdc++-4.8.5-28.el7.x86_64 -y

2、修复/lib/ld-linux.so.2: bad ELF interpreter: No such file or directory问题

yum install glibc.i686 -y

3、 修复error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory

yum install zlib.i686 -y

4、修复error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

先查找这个库存在于哪个安装包中

yum whatprovides libstdc++.so.6

执行结果：

[root@bogon ~]# yum whatprovides libstdc++.so.6

Loaded plugins: fastestmirror

Loading mirror speeds from cached hostfile

 * base: mirrors.njupt.edu.cn

 * extras: mirrors.163.com

 * updates: mirrors.njupt.edu.cn

libstdc++-4.8.5-36.el7.i686 : GNU Standard C++ Library

Repo        : base

Matched from:

Provides    : libstdc++.so.6

可以看到包  libstdc++-4.8.5-36.el7.i686

安装libstdc++-4.8.5-36.el7.i686

yum install libstdc++-4.8.5-36.el7.i686 -y

到此就解决了缺少共享库到问题
