The version of the libstdc++ library is mismatched. Run the following command to find it:

find / -name "libstdc++.so.6*"
strings /lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX

Look for GLIBCXX_3.4.30. If it exists, create a symbolic link to it. If it doesn't exist, upgrade it by running the following commands:

apt-get install software-properties-common
add-apt-repository ppa:ubuntu-toolchain-r/test
apt-get update
apt-get install libstdc++6

我也是这个错误 strings /lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX 是有结果的，link了但还是不行。。
