最近在linux跑nodejs碰到版本问题，记录如下：
问题1：
node: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.14' not found (required by node)
node: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.18' not found (required by node)
node: /usr/lib64/libstdc++.so.6: version `CXXABI_1.3.5' not found (required by node)
node: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.15' not found (required by node)
node: /lib64/libc.so.6: version `GLIBC_2.16' not found (required by node)
node: /lib64/libc.so.6: version `GLIBC_2.17' not found (required by node)
node: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by node)
解决：
下载libstdc++.so.6.0.17更换libstdc++.so.6.0.13；

问题2：
node: error while loading shared libraries: libstdc++.so.6: wrong ELF class: ELFCLASS32
这个问题的出现是使用libstdc++.so.6.0.19（本来就是64位），郁闷了。
解决：
突发奇想把nodejs版本降到10（原来是12），问题解决；
