我试图在Linux机器上安装一个网站，我得到了宝石错误，谷歌告诉我更新宝石。所以我做了..来找出这个网站是他们的产品，现在已经下来了。我运行了以下命令，现在发生了这种情况。
sudo gem update --system
我尝试过：gem update --system 1.8.25
并收到以下错误：

您的gem降级过程失败，因为它无法生成文档（可能是RDoc版本问题）。
您可以尝试运行降级而不生成如下文档：
gem update --system 1.8.25 --no-rdoc --no-ri
看看是否有助于完成降级...

更新系统宝石时，版本会发生变化。您的项目正在加载一些新版本，但某些内容无效。
您首先应该尝试访问您的应用并运行bundle（或sudo bundle，如果您已按此方式设置）。这将使用您的Gemfile.lock找到要安装的正确版本。
如果仍然无法正常工作，请尝试确定哪个gem失败并在Gemfile中指定工作版本。类似于gem 'mygem', '~> 1.0.0'的地方，其中已知版本正在运行。然后运行bundle或sudo bundle进行更新。
您应该尝试让您的生产机器与您的本地环境保持一致。应该使用相同的Ruby版本，理想情况下是类似的架构。这样，两个地方都会安装相同的宝石，您可以在本地进行调试。
我还听到过建议将您的项目宝石与您的系统隔离开来。您可以使用rbenv或RVM来执行此操作。然后，您不再使用sudo来安装宝石。我以为我不确定这是否可以解决任何问题。
