尝试编译C ++ 17文件系统库；得到“找不到版本”

Question

我最近安装了gcc 9.1.0，从那时起，我一直在探索它的功能。我最近尝试使用文件系统库编译一个简单程序：

#include <iostream>
#include <filesystem>

int main() {
    for(auto& file : std::filesystem::recursive_directory_iterator("./")) {
        std::cout << file.path() << '\n';
    }
}

程序可以正常编译，但是当我尝试运行可执行文件时，出现错误消息：

./a.out: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version GLIBCXX_3.4.26' not found (required by ./a.out)

编译命令为g++ -std=c++17 file.cpp，当我检查g ++的版本时，它给出了以下信息：

g++ (GCC) 9.1.0
Copyright (C) 2019 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO

所以我知道版本是正确的。如果我以详细模式运行compile命令，它将为我提供以下信息：
