我试图在Linux盒子上安装一个网站，我遇到了GEMS错误，Google告诉我更新GEMS。所以我做到了..找出网站是他们的生产，现在已经下降了。我运行以下命令，现在发生了。
sudo gem update --system
我尝试过： gem update --system 1.8.25
并有以下错误：

您的宝石降级过程失败了，因为它无法生成文档（可能是RDOC版本问题）。
您可以尝试在不生成这样的文档的情况下尝试运行降级：
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GEMS时，版本bump。您的项目正在加载一些新版本，而某些内容则无法正常工作。
，您应该首先尝试将CD降低到您的应用程序中并运行bundle（或sudo bundle，如果您使用此方式）。这将使用您的Gemfile.lock来找到要安装的正确版本。
如果事情仍然不起作用，请尝试查明哪个GEM失败，并在Gemfile中指定工作版本。类似于gem 'mygem', '~> 1.0.0'，该版本的工作正常。然后运行bundle或sudo bundle进行更新。
您应该尝试使生产机器与当地环境保持均衡。应该使用相同的红宝石版本，理想情况下是类似的架构。这样，相同的宝石将被安装在两个地方，您可以在本地进行调试。
我还听到了建议将项目的宝石与系统隔离开来的建议。您可以使用rbenv或RVM进行此操作。然后，您将不再使用sudo安装宝石。以为我不确定这是否可以在这里解决任何问题。
