如何在 ubuntu 20.04 上解决 ruby 2.7.4 的 "incompatible library version" 问题？

Question

你好，这是我的第一个问题。我正在尝试在我的服务器上构建一个 redmine 系统，但遇到了一些问题。

我的系统-ubuntu20.04 + nginx1.18 + mariadb10.3.30 + ruby2.7.4 + redmine4.2.2 / 使用rbenv安装ruby

当我尝试连接 redmine 服务器时，出现此错误

App 716658 output: Error: The application encountered the following error: libruby.so.2.7: cannot open shared object file: No such file or directory - /opt/redmine/vendor/cache/ruby/2.7.0/gems/mysql2-0.5.3/lib/mysql2/mysql2.so (LoadError)

所以我做到了 cd /usr/lib

ln -s /root/.rbenv/versions/2.7.4/lib/libruby.so.2.7 libruby.so.2.7

然后发生库版本不兼容的错误

App 722799 output: Error: The application encountered the following error: incompatible library version - /opt/redmine/vendor/cache/ruby/2.7.0/gems/mysql2-0.5.3/lib/mysql2/mysql2.so (LoadError)

我尝试了 gem pristine --all 但没有成功。

我该如何解决这个问题？出现了这么多错误，所以我想我的设置有问题。

您似乎已经配置了捆绑器（Ruby 项目的 gem 版本管理器）以在与通常系统不同的位置为 Redmine 安装 gems gems，即到/opt/redmine/vendor/cache.

因此，通常的 gem 命令不会触及那些安装了捆绑程序的 gem，因为 gem 不知道它们。要重新安装所有捆绑器管理的 gems，您可以运行在您的 Redmine 目录中执行以下命令（i/e/ 包含 Gemfile 的目录：

bundle pristine

这实际上与 gem pristine --all 相同，但仅适用于捆绑程序管理的 gem。有关详细信息，请参阅 the documentation。
