如何解决在ubuntu20.04上使用ruby2.7.4的“不兼容库版本”问题？

Question

你好这是我的第一个问题。我正试图在我的服务器上建立一个红地雷系统，但也面临一些问题。

我的系统- ubuntu20.04 + nginx1.18 +maradb10.3.30+ ruby2.7.4 +redbre-4.2.2/使用rbenv安装ruby

当我试图连接红矿服务器时，我得到了这个错误

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

然后发生不兼容的库版本错误。

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)

我试过gem pristine --all，但没有起作用。

我该如何解决这个问题？发生了这么多错误，所以我想我的设置有一个问题。

您似乎已经配置了bundler ( Ruby的一个创业板版本管理器)，将Redmine的gems安装在与通常的系统gems不同的位置，即/opt/redmine/vendor/cache。

因此，通常的gem命令不会触及那些安装在绑定程序中的宝石，因为gem不知道它们。要重新安装所有邦德勒托管的gems，您可以在您的Redmine目录(i/e/包含Gemfile的目录)中运行以下命令

bundle pristine

这实际上与gem pristine --all相同，但只适用于绑定程序管理的宝石。详情请参见文献资料。
