![安装 rails 12.04 错误](https://linux22.com/image/848050/%E5%AE%89%E8%A3%85%20rails%2012.04%20%E9%94%99%E8%AF%AF.png)
一切顺利,直到安装轨道的命令
gem install rails
我收到此错误:
ERROR: While executing gem ... (Gem::RemoteFetcher::UnknownHostError)
no such name (http://api.rubygems.org/api/v1/dependencies?gems=activerecord-deprecated_finders)
每次尝试错误消息时都会显示不同的 gem 依赖项?gems=.......
对这个问题有什么建议吗?
编辑:
这是执行 coomand 后的完整堆栈跟踪gem install rails -V

我上周按照这里的说明安装了轨道:
http://railsapps.github.io/installrubyonrails-ubuntu.html
各操作指南之间的显著差异如下:
--ruby
在命令中添加:
\curl -L https://get.rvm.io | bash -s stable --ruby
更新 RVM 的命令如下:
rvm get stable --autolibs=enable
要使用的 ruby 版本已明确设置:
rvm --default use ruby-2.1.0
js.Node 的安装
sudo apt-get install nodejs
安装 rails 之前也要明确设置版本:
rvm use [email protected] --create
