tesseract gem赢得'；不能用Ruby编译

这里完全没有问题，但无法找出如何克服此错误。我希望在运行Centos 6的Linux服务器上安装并运行“tesseract”gem。结果似乎是-ltesseract应该在/usr/bin/ld中，但不是

我已经阅读了其他发布的tesseract/Ruby问题，但我认为我没有这些问题

非常感谢您的帮助

我假设是这样的

yum安装tesseract

$sudo yum安装tesseract加载的插件：fastestmirror、priorities、refresh packagekit、，从缓存主机文件加载镜像的安全速度*基本：mirrors.vooservers.com*epel:mirror.bytemark.co.uk*附加：mirror.sov.uk.goscomb.net*更新：mirrors.vooservers.com设置安装过程无可用软件包tesseract。错误：无需执行任何操作从下载rpm软件包，然后使用yum-nogpgcheck安装tesseract-3.02.02-3.1.i686.rpm（带软件包的cd-to-dir）P.S：您应该始终检查来自不受信任源的软件包您可能还需要添加存储库RPMforge，然后安装与常规软件包类似的软件包。yum安装tesseract tesseract en我认为这是最简单的方法。很抱歉继续成为这里的一个无名小卒，但是。。。a） 你的前两条评论说：下载这个东西，但永远不要相信我告诉你下载的东西（对吧？）。所以，根据你的建议，我还没有下载它。：/b） 因此，我遵循了您第三条评论中的说明，但没有骰子：“没有可用的包tesseract。没有可用的包tesseract en。”
