libstdc++.so.6: version `GLIBCXX_3.4.26’ not found
首先我们可以吧libstdc++啥的看成一个库，然后代码可能运行时候报错说这个库没找到或者这个库里面版本没找到。那就是要更新了。当然常规更新方法可以但是如果更新不行不妨试试这个方法
先用
locate libstdc++.so.6 找出这个库的不同版本，因为通常这个库随着系统升级，conda等多个位置存在高级版本 libstdc++.so.6.3.30、 libstdc++.so.6.4.30等。
以该报错信息微为例子

问题就解决了，通常有很多库不存在啥的问题，都可以使用该方法，去找它的同文件版本或升级版本去创建软连接。
