安装geoip_city gem时出错

Question

当我尝试安装geoip_city gem时，我总是收到错误消息。我已经将GeoIP C库安装到了/ opt/GeoIP，但是这个gem似乎没有选择它。我已经试过：

Building native extensions. This could take a while... 
ERROR: Error installing geoip_city:

Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/geoip_city-0.2.0 for inspection.

Answer 1

cantorrodista是在正确的轨道上，虽然。我必须像这样运行命令： sudo env ARCHFLAGS =“ - arch i386”gem install geoip_city - --with-geoip-dir =/opt/GeoIP

Answer 2

我认为你必须通过ARCHFLAGS参数以指示要一个64位arquitecture就可以了：：

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 

所有输出这个错误的

须藤ENV ARCHFLAGS = “ - 拱x86_64的” 创业板安装geoip_city - --with-geoip的-DIR = /选择/ geoip的
