在linux安装nodejs，配置好环境变量后，node -v出错：
bash: /usr/local/node/bin/node: /lib/ld-linux.so.2: bad ELF interpreter: 没有那个文件或目录
按照提示的意思是解释器出了问题，度娘了一下，应该这样能解决：
##切忌不要输入此命令，我自己给自己挖的坑，后面就能看到
sudo yum install glibc.i686
试一下：
node -v
报错：
error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

错误： Multilib version problems found. This often means that the root
cause is something else and multilib version checking is just
pointing out that there is a problem. Eg.:
1. You have an upgrade for libstdc++ which is missing some
dependency that another package requires. Yum is trying to
solve this by installing an older version of libstdc++ of the
different architecture. If you exclude the bad architecture
yum will tell you what the root cause is (which package
requires what). You can try redoing the upgrade with
--exclude libstdc++.otherarch ... this should give you an error
message showing the root cause of the problem.
2. You have multiple architectures of libstdc++ installed, but
yum can only see an upgrade for one of those architectures.
If you don't want/need both architectures anymore then you
can remove the one with the missing update and everything
will work.
3. You have duplicate versions of libstdc++ installed already.
You can use "yum check" to get yum show these errors.
...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).
保护多库版本：libstdc++-4.8.5-36.el7.i686 != libstdc++-4.8.5-11.el7.x86_64
多版本问题，需要关闭保护
解决方式：
yum whatprovides libstdc++.so.6
yum install --setopt=protected_multilib=false libstdc++-4.8.5-36.el7.i686
报错：
Transaction check error:
file /usr/share/gcc-4.8.2/python/libstdcxx/v6/printers.pyc from install of libstdc++-4.8.5-36.el7.i686 conflicts with file from package libstdc++-4.8.5-11.el7.x86_64
file /usr/share/gcc-4.8.2/python/libstdcxx/v6/printers.pyo from install of libstdc++-4.8.5-36.el7.i686 conflicts with file from package libstdc++-4.8.5-11.el7.x86_64
导致该问题原因是因为版本冲突了，因为之前使用了sudo yum install glibc.i686安装了一个版本，现在又要安装另外一个版本
解决方式：
yum update libstdc++-4.8.5-11.el7.x86_64
yum install --setopt=protected_multilib=false libstdc++-4.8.5-36.el7.i686
终于解决
