我已经开发了一个使用
Ruby v2和Rails v4的rails web项目.这在我目前的系统中是完美的,当我尝试在另一台Linux机器(Ubuntu 12.4)上运行这个项目时,我得到一个Tidy_tds错误.
@H_502_2@捆绑安装时出现此错误,
@H_502_2@错误详情如下
Gem::Ext::BuildError: ERROR: Failed to build gem native extension. /home/action/.rvm/rubies/ruby-2.1.1/bin/ruby extconf.rb checking for iconv_open() in iconv.h... yes checking for sybfront.h... no ----- freetds is missing.

解决方法
看来你没有在这台机器上安装freetds：
sudo apt-get install freetds-dev@H_502_2@如果您看到freetds-dev软件包的详细信息,您将看到它缺少文件sybfront.h @H_502_2@没有我知道的宝石,建立tiny_tds gem需要编译.但是,您应该可以使用MiniPortile构建您自己的宝石版本. @H_502_2@而不是使用正常的gem安装机制,您需要从githib克隆tiny_tds,然后为您的环境构建本机gem.此过程将包括下载用于编译宝石的特定版本的freetds. @H_502_2@这应该可以解决无法安装freetds-dev软件包的问题,但确实有缺点,如果将来更新tiny_tds gem,那么每次都需要重复这个过程 – 你不能简单地利用捆绑更新. @H_502_2@您需要遵循的步骤详细here.
