【问题描述】：
我正在尝试在 32 位 Ubuntu EC2 AMI 上安装 Shapado，并在安装过程中将 ruby 更新到 1.9.2。但是，我收到此错误
ubuntu@domU....:/var/rails/shapado$ sudo rake gems:install
rake aborted!
Gemfile syntax error:

不是 ruby 用户，我猜这与 gems/1.8 有关，但如果我尝试使用更新
gem update --system
我收到警告说此更新系统在 Debian 上已禁用。
ubuntu@domU-12-31-38-04-9E-D2:/var/rails/shapado$ gem update --system
ERROR: gem update --system is disabled on Debian, because it will overwrite the
content of the rubygems Debian package, and might break your Debian system in s
ubtle ways. The Debian-supported way to update rubygems is through apt-get, usin
g Debian official repositories.
If you really know what you are doing, you can still update rubygems by setting
the REALLY_GEM_UPDATE_SYSTEM environment variable, but please remember that this
is completely unsupported by Debian.
那么，拥有 1.8 个 gem 是否会出现错误，如果是，那么最好的更新方法是什么？如果这样更好的话，我可以核弹整个事情并重新开始。我想我应该指定一个特定的版本，而不是仅仅按照安装说明http://shapado.com/questions/how-to-install-shapado-on-amazon-ec2
【问题讨论】：
-
我在运行 Ruby
-
嗯。我明确安装了 ruby 1.9.2，但是是的，当我尝试安装 1.8.7 时，我看到了 :( 是时候核弹再试一次了。
-
即使在 sudo update-alternatives --config ruby 和 gem 之后，使用 ruby -v 给我 ruby1.9.3 问题仍然存在
