Question

尝试使用ruby gems安装rails 3.0.1时出现以下错误

   iHAL-2:~ $ gem install rails --version 3.0.1
    ERROR:  Could not find a valid gem 'rails' (= 3.0.1), here is why:
              Unable to download data from https://rubygems.org/ - no such name (https://api.rubygems.org/specs.4.8.gz)
    ERROR:  Possible alternatives: rails

我的RVM设置应该没问题：

iHAL-2:~$ rvm get stable
Downloading https://get.rvm.io
Downloading https://github.com/wayneeseguin/rvm/archive/stable.tar.gz

Upgrading the RVM installation in /Users/iHal9000/.rvm/
    RVM PATH line found in /Users/iHal9000/.profile /Users/iHal9000/.bashrc /Users/iHal9000/.zshrc.
    RVM sourcing line found in /Users/iHal9000/.profile /Users/iHal9000/.bash_profile /Users/iHal9000/.zlogin.
Upgrade of RVM in /Users/iHal9000/.rvm/ is complete.

# iHAL-2,

我不明白其中的区别，但这对我有用：

gem install rails -v 3.0.1
