ruby - Heroku FreeTDS，如何将 Rasil SQL Server 与带有 Multi Buildpacks 的 TinyTDS 一起使用

Question

我必须在我的 Rails 4.2.3 上使用“Tiny TDS”gem，当然在 Heroku 的 cedar-14 上我不能，因为 FreeTDS 已经不在上面了。

如何在 Heroku cedar-14 上使用 FreeTDS？

我在网上查找，发现了这个:

https://github.com/foraker/heroku-buildpack-freetds

他说将它与“heroku-buildpack-multi”一起使用，这个:https://github.com/ddollar/heroku-buildpack-multi

但我不明白怎么办!

我必须在本地电脑上创建“.buildpacks”文件吗？

然后我必须“git push heroku master”？

这个程序今天仍然有效吗？

或者我必须使用这个:https://devcenter.heroku.com/articles/using-multiple-buildpacks-for-an-app

请帮助我，谢谢。

更新:

我找到了如何使用这个在 Heroku 上安装 FreeTDS:

https://github.com/eltiare/heroku-buildpack-freetds

用这个:

https://github.com/ddollar/heroku-buildpack-multi

使用这个 .buildpacks:

https://github.com/eltiare/heroku-buildpack-freetds.git#master
https://github.com/heroku/heroku-buildpack-ruby.git#master

但是现在，在部署之后，我得到了一个错误:

/app/vendor/bundle/ruby/2.1.0/gems/activesupport-4.2.3/lib/active_support/dependencies.rb:274:in `require': libsybdb.so.5: cannot open shared object file: No such file or directory - /app/vendor/bundle/ruby/2.1.0/extensions/x86_64-linux/2.1.0-static/tiny_tds-0.6.2/tiny_tds/tiny_tds.so (LoadError)

然后应用程序崩溃。

如何修复？

这些是日志:

这是什么:

libsybdb.so.5 ?

另一项更新:

我还尝试将下载 url 更改为:

https://fossies.org/linux/privat/freetds-0.95.19.tar.gz

但是什么都没有，同样的错误:

LoadError: libsybdb.so.5: cannot open shared object file: No such file or directory - /tmp/build_77614230336e05e686009861d71719ea/vendor/bundle/ruby/2.1.0/extensions/x86_64-linux/2.1.0-static/tiny_tds-0.6.2/tiny_tds/tiny_tds.so

好像其他人也遇到过这个问题。查看this particular procedure这似乎奏效了。
