Ruby nokogumbo在Gentoo上的安装因捆绑和gems而失败

ruby版本：

ruby 2.4.4p296（2018-03-28修订版63013）[x86\u 64-linux]

我可以用portage安装nokogumbo，但不能用gem或bundle安装它。

我尝试将文件读取到配置包，但不知道如何配置

我还尝试添加

——使用ldflags=-Wl，--no未定义的
，它也会失败

$ gem install nokogumbo

我尝试运行
gem install nokogumbo--ldflags='-L-Wl，-O1-Wl，--as-needed-fstack protector-rdynamic-Wl，-export dynamic'
，它引用了ebuild文件，然后成功了！
现在，我将其用于bundle。
谷歌的第一个结果：
sudo apt get install libxml2 dev libxml2 doc
。“你试过了吗？”汤姆洛德：当然，我找到了。但我用的是gentoo，不是ubuntu。我的系统上安装了libxml2。
