ROR +无法安装tiny_tds
在这里，我试图从MS-SQL Server 2008获取数据到Ubuntu 10上的我的Rails应用程序。但是我无法安装tiny_tds 。 我按照github给出的步骤进行操作。 但没有回应。 请指导我正确设置。
使用gem命令:: gem install tiny_tds
这个命令也是:: gem install tiny_tds –with-freetds-include=/usr/local/include/freetds –with-freetds-lib=/usr/local/lib
错误：

你在安装gem之前安装了freeTDS吗？
sudo apt-get install freetds-dev
然后
gem install tiny_tds
上面的答案是正确的，这只是那些喜欢自制软件的mac人的另一个注释
它命令基本上完全相同：
brew install freetds
正如ar3所说，上面的答案是正确的。 对于那些在CentOS上的人来说，RPM是freetds-devel，而不是freetds-dev（以防你和sysadmin一样软）。
yum install freetds-devel
试试这个，
从以下链接下载freetds并安装它
freetds下载链接
按照以下说明安装：
cd /home/user/Downloads/ tar -zxvf freetds-1.00.23.tar.gz
然后
cd freetds-1.00.23/ ./configure make sudo make install
完成freetds安装后，尝试使用bundle install
这将解决freetds依赖问题。
