Rails pg gem不兼容的库版本

I'm getting the following 'incompatible library version' error when I try and access my Ruby on Rails website in development mode.

当我尝试在开发模式下访问我的Ruby on Rails网站时,我收到以下“不兼容的库版本”错误。

I've tried updating PostgreSQL using yum update, then gem uninstall pg and gem install pg. But I continue to get the same problem. The gem itself installs without any errors.

我尝试使用yum update更新PostgreSQL,然后使用gem uninstall pg和gem install pg。但我继续得到同样的问题。 gem本身安装没有任何错误。

I'm not really sure how to debug further. What do I need to do to install, update or reference the necessary compatible libraries?

我不确定如何进一步调试。如何安装,更新或引用必要的兼容库需要做什么?

Try:

$ gem install pg
$ gem pristine --all

It looks as if you might be suffering from this bug: https://bitbucket.org/ged/ruby-pg/issues/229/pg_exit-improperly-linked-when-using-rvm

看起来你可能正在遭受这个错误:https://bitbucket.org/ged/ruby-pg/issues/229/pg_exit-improperly-linked-when-using-rvm

The libruby version should be different, apparently.

libruby版本应该是不同的,显然。

However: I have the same error message, and my libruby is correct, so I think that there might be more going on...

但是:我有相同的错误消息,我的libruby是正确的,所以我认为可能会有更多...

#3

I get the same error when I call in console rails c. Calling bundle exec rails c removed that error.

当我在控制台导轨c中调用时,我得到了同样的错误。调用bundle exec rails c删除了该错误。

After looking at the discussion on https://bitbucket.org/ged/ruby-pg/issues/229/pg_ext-improperly-linked-when-using-rvm, the only way I've managed to make it work on Arch Linux was removing the system-wide ruby, then I did gem uninstall pg followed by gem install pg --version 0.18.3. This made the issue go away. I reinstalled the system-wide ruby after that. On my setup I had no packaged depending on the system-wide ruby, so it was okay to remove it, but YMMV.

在查看https://bitbucket.org/ged/ruby-pg/issues/229/pg_ext-improperly-linked-when-using-rvm上的讨论后,我设法使其在Arch Linux上运行的唯一方法正在删除系统级的ruby,然后我做了gem uninstall pg,然后是gem install pg --version 0.18.3。这使问题消失了。之后我重新安装了系统范围的ruby。在我的设置上,我没有打包取决于系统范围的红宝石,所以可以删除它,但是YMMV。
