这个错误是在bundle install时显示的，

-----
freetds is missing.
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.

Gem files will remain installed in /home/action/.rvm/gems/ruby-2.1.1/gems/tiny_tds-0.6.1 for inspection.
Results logged to /home/action/.rvm/gems/ruby-2.1.1/extensions/x86_64-linux/2.1.0/tiny_tds-0.6.1/gem_make.out
An error occurred while installing tiny_tds (0.6.1), and Bundler cannot continue.
Make sure that `gem install tiny_tds -v '0.6.1'` succeeds before bundling.
我也尝试过单独安装 tiny_tds，但我仍然遇到同样的问题
I have also tried installing tiny_tds seperatly, but still i am getting the same issue
gem install tiny_tds -v '0.6.1'
我的宝石文件，
source 'https://rubygems.org'

推荐答案
看起来你这台机器上没有安装 freetds:
Looks like you don't have freetds installed on this machine:
sudo apt-get install freetds-dev
如果您看到 freetds-dev 包的详细信息，您将看到它缺少文件 sybfront.h
If you see the details of the freetds-dev package you will see it has the missing file sybfront.h
我不知道 freetds 的 gem 并且构建 tiny_tds gem 需要它进行编译.但是，您应该可以使用 MiniPortile 构建自己的 gem 版本.
There is no gem that I know for freetds and building the tiny_tds gem requires it to compile. However it should be possible for you build your own version of the gem using MiniPortile.
您需要从 GitHub 克隆 tiny_tds，然后为您的环境构建本机 gem，而不是使用普通的 gem install 机制.此过程将包括下载用于编译 gem 的特定版本的 freetds.
Rather than using the normal gem install mechanism you need to clone the tiny_tds from GitHub and then build a native gem for your environment. This process will include downloading a specific version of freetds which is used to compile the gem against.
这应该可以让您解决无法安装 freetds-dev 包的问题，但确实有一个缺点，如果 tiny_tds gem 将来更新，您每次都需要重复此过程 - 您不能简单地利用 bundle update.
This should get you round the problem of not being able to install freetds-dev package, but does have the disadvantage that if tiny_tds gem is updated in the future you will need to repeat this process each time - you can't simply take advantage of bundle update.
此处详细介绍了您需要遵循的步骤.
