安装geoip_city gem时出错
我在尝试安装geoip_city gem时遇到错误。 我已经将GeoIP C库安装到/ opt / GeoIP，但是gem似乎没有把它拿起来。 我试过了：
sudo gem install geoip_city -- --with-geoip-dir=/opt/GeoIP sudo gem install geoip_city -- --with-geoip-lib=/opt/GeoIP/lib sudo gem install geoip_city -- --with-geoip-dir=/opt/GeoIP --with-geoip-lib=/opt/GeoIP/lib 所有这些输出此错误：

但是，cantorrodista在正确的轨道上。 我不得不像这样运行命令：sudo env ARCHFLAGS =“ – arch i386”gem install geoip_city – –with-geoip-dir = / opt / GeoIP
我认为您必须传递ARCHFLAGS参数以指示将为64位arquitecture构建：
sudo env ARCHFLAGS =“ – arch x86_64”gem install geoip_city – –with-geoip-dir = / opt / GeoIP
