ROR + 无法安装 tiny_tds

Question

在这里，我试图从 MS-SQL Server 2008 获取数据到我在 Ubuntu 10 上的 Rails 应用程序。但我无法安装 tiny_tds。我按照 github 上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：

Answer 1

您是否在安装 gem 之前安装了 freeTDS？

sudo apt-get install freetds-dev

然后

gem install tiny_tds

Answer 2

上面的答案是正确的，这只是给那些喜欢自制的Mac用户的补充说明

It 命令本质上是一样的：

brew install freetds

Answer 3

正如 ar3 所说，上面的答案是正确的。对于 CentOS 上的用户，RPM 是 freetds-devel，而不是 freetds-dev（以防你像我一样对系统管理员不熟悉）。

yum install freetds-devel

Answer 4

试试这个，

从以下链接下载 freetds 并安装它

freetds download link

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 

freetds安装完成后，试试bundle install

这将解决 freetds 依赖问题。
