我使用 Ruby v2 和 Rails v4 开发了一个 Rails Web 项目。它在我当前的系统中运行良好，当我尝试在另一台 Linux 机器 (Ubuntu 12.4) 中运行该项目时，出现 Tidy_tds 错误。
此错误在 bundle install 时显示，
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.
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

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.
我也尝试单独安装 tiny_tds，但我仍然遇到同样的问题
gem install tiny_tds -v '0.6.1'
我的 gem 文件，
source 'https://rubygems.org'

为什么会出现这个错误以及如何解决这个问题。
感谢任何帮助
最佳答案
看起来你没有在这台机器上安装 freetds:
sudo apt-get install freetds-dev
如果您看到 freetds-dev 的详细信息包你会看到它有丢失的文件 sybfront.h
据我所知，freetds 没有 gem，构建 tiny_tds gem 需要编译它。但是，您应该可以使用 MiniPortile 构建自己的 gem 版本。
您需要从 GitHub 克隆 tiny_tds，然后为您的环境构建原生 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。
这应该可以解决无法安装 freetds-dev 包的问题，但如果 tiny_tds gem 将来更新，则确实存在缺点每次都需要重复此过程 - 您不能简单地利用 bundle update。
需要遵循的步骤很详细here .
