我正在尝试安装taglib-ruby但不断收到相同的错误：
xyz@ubuntu:~$ sudo gem install taglib-ruby
Building native extensions. This could take a while...
ERROR: Error installing taglib-ruby:

You must have libstdc++ installed.
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.

我按照自述文件中的说明进行安装libtag1-dev并仔细检查是否安装了 libstdc++（如果我错过了文件，我什至查看了 Ubuntu 软件中心）。我发现的唯一类似问题是这个，但我已经尝试明确定义opt-dirandopt-include也无济于事。
我不得不承认我对这个主题甚至 Ubuntu 都不是很熟悉，所以我很可能只是忽略或完全错过了有关错误消息的一些明显内容。
