我的rails应用程序工作正常，但最近Dreamhost移出了他们的服务器（*类似的东西），现在我无法通过capistrano进行部署..
我收到此错误消息：
libmysqlclient_r.so.15: cannot open shared object file: No such file or directory - /home/soprojetos/cap/shared/bundle/ruby/1.8/gems/mysql2-0.3.11/lib/mysql2/mysql2.so

答案 0 :(得分：0)
我猜测有一次操作系统升级，并且在某些时候，某些与mysql相关的内容被删除或未升级。
这对我在Ubuntu 16.04.4上有用：
gem uninstall mysql2
sudo apt-get install libmysqlclient-dev
gem install mysql2
您可能需要重启apache或任何提供错误的服务。
请注意，如果你这样做
gem uninstall mysql2
gem install mysql2
你的系统应该告诉你需要安装什么来安装mysql2 gem，在我的例子中是上面的apt-get命令。

尝试交换mysql2 gem https://rubygems.org/gems/mysql2
