我正在尝试使用厨师社区食谱opsworks_ruby来部署rails应用程序。我目前遇到了一个问题，tiny_tds版本0.9.5.beta.10。
尝试使用以下命令迁移数据库时：
/usr/local/bin/bundle exec rake db:migrate
我收到此错误：
STDERR: rake aborted!
LoadError: libruby.so.2.1: cannot open shared object file: No such file or directory - /srv/www/api/shared/vendor/bundle/ruby/2.2/extensions/x86_64-linux/2.2/tiny_tds-0.9.5.beta.10/tiny_tds/tiny_tds.so

然而，当我ssh到服务器和
file /srv/www/api/shared/vendor/bundle/ruby/2.2/extensions/x86_64-linux/2.2/tiny_tds-0.9.5.beta.10/tiny_tds/tiny_tds.so
我将此作为回复：
[...]tiny_tds.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, BuildID[sha1]=cce05b6143516778339554cb7b1e2db232bb155e, not stripped
所以文件显然在那里，为什么不能找到它？
我目前安装了ruby 2.2.4。

ldd /srv/www/api/shared/vendor/bundle/ruby/2.2/extensions/x86_64-linux/2.2/tiny_tds-0.9.5.beta.10/tiny_tds/tiny_tds.so
给我这个：

libfreebl3.so => /lib64/libfreebl3.so (0x00007fee582dd000)
另外，研究路径和诸如此类的东西：
$ echo $PATH
> /usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/opt/aws/bin:/home/ec2-user/.local/bin:/home/ec2-user/bin
$ echo $GEM_HOME
>
$ echo $GEM_PATH
>
$ which ruby
> /usr/bin/ruby
$ /usr/bin/ruby -v
> ruby 2.2.4p230 (2015-12-16 revision 53155) [x86_64-linux-gnu]
我注意到我没有GEM_HOME或GEM_PATH，但我的红宝石看起来不错？
有人可以帮我解决这个问题吗？
