我最近在alpine 14容器中升级了一个Rails应用程序到6.1，其中ruby 3.0.1编译并安装了所有必需的gem，但它无法启动：
LoadError: Error loading shared library libmariadb.so.3: No such file or directory (needed by /usr/local/bundle/gems/mysql2-0.5.3/lib/mysql2/mysql2.so) - /usr/local/bundle/gems/mysql2-0.5.3/lib/mysql2/mysql2.so

我不知道它到底想装什么，从哪里装。
我已经将libmariadb.so.3（来自mariadb-connector-c）安装到/usr/lib中，并且还链接到/usr/local/lib。
/usr/local/bundle/gems/mysql 2 -0.5.3/lib/mysql 2/mysql2.so也在那里。
我在启动之前没有删除任何软件包或gem，并且在包安装过程中没有错误。
我做错了什么？
