本人linux镜像为centos7，安装gcc的过程可以看上次的发布，后安装node时出现一下问题：
对文件夹下进行make && make install时，出现以下问题：
/gcc/node/node-v11.15.0/out/Release/torque: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by /gcc/node/node-v11.15.0/out/Release/torque) /gcc/node/node-v11.15.0/out/Release/torque: /lib64/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by /gcc/node/node-v11.15.0/out/Release/torque) /gcc/node/node-v11.15.0/out/Release/torque: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /gcc/node/node-v11.15.0/out/Release/torque)
首先
find / -name "libstdc++.so*"
将找到的动态库libstdc++.so.6.0.21复制到/usr/lib64（最新动态库）
cp /usr/local/src/gcc-5.4.0/gcc-build-5.4.0/stage1-x86_64-unknown-linux-gnu/libstdc++-v3/src/.libs/libstdc++.so.6.0.21 /usr/lib64
切换工作目录至/usr/lib64，删除原来的软连接， 将默认库的软连接指向最新动态库
cd /usr/lib64 rm -rf libstdc++.so.6 ln -s libstdc++.so.6.0.21 libstdc++.so.6
