这里我尝试从Ubuntu 10上的MS-SQL Server 2008获取数据到我的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。
使用过的gem命令:: gem install tiny_tds
此命令以及:: gem install tiny_tds –with-freetds-include=/usr/local/include/freetds –with-freetds-lib=/usr/local/lib
错误：

您在安装gem之前是否安装了freeTDS？
sudo apt-get install freetds-dev
然后
gem install tiny_tds
答案 1 :(得分：38)
上面的答案是正确的，这只是那些喜欢自制的
的mac人员的补充说明它的命令基本上完全相同：
brew install freetds
答案 2 :(得分：6)
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（如果你和sysadmin一样软，我会这么做。）
yum install freetds-devel
答案 3 :(得分：0)
试试这个，
从以下链接下载freetds并安装
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，请尝试使用bundle install
这将解决freetds依赖问题。
