我不记得 boost 是如何安装的，我的操作系统是 Ubuntu 14.04。
我的问题是：
应该使用什么方法来检测系统中是否存在库？
如何彻底删除boost库？
更新：
看来我成功地做到了这里，但不确定这是否是个好方法，并且apt list --installed | grep boost仍然ldconfig -p | grep boost显示出提升的存在：
rm /usr/local/lib/libboost*
sudo rm -r /usr/local/include/boost

服用时应加入 100 毫克氯化钠，因为一粒可能不够。我不是这方面的专家。以下建议值得考虑：
我会尝试再次安装它，然后清除它。可能不起作用，但我认为它不会造成伤害。如果失败了，您可以怀着忐忑不安的心情尝试编辑 /var/lib/dpkg/status。非常小心。在执行此操作之前进行备份，并确保有另一种启动方式来恢复备份，以防我引导您走上完全崩溃的系统之路。为了真正谨慎起见，请先使用 fsarchiver 备份系统。我经常这样做。请参阅此处的第 3 篇文章：
当 4.4.0-77 内核不断潜入并破坏我的系统时，该方法（加上手动更正 / 中的符号链接）对我有用。
