请帮帮我！ 我有一个系统freeBSD 10 我在RVM上的rails上安装了rvm和ruby。
[glafir@ ~/RoR/fips]$ whereis rvm

rvm 1.25.25 (stable) by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal Papis <mpapis@gmail.com> [https://rvm.io/]
[glafir@ ~/RoR/fips]$ ruby -v
ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-freebsd10.0]
我尝试安装gem nokogiri并收到此错误：

我已经安装了libxml2。
[glafir@ ~/RoR/fips]$ pkg info -a |grep libxml2

救救我！请帮帮我！

尝试在nokogiri和额外路径之后使用--：
gem install nokogiri -- --use-system-libraries --with-xml2-lib=/usr/local/lib \
--with-xml2-include=/usr/local/include/libxml2/libxml --with-xslt-lib=/usr/local/lib \
--with-xslt-include=/usr/local/include/libxslt --with-iconv-lib=/usr/local/lib \
--with-iconv-include=/usr/local/include
注意：以上命令在带有libiconv的FreeBSD 9.2上成功运行（FreeBSD 10.0内置了iconv到world / base）
