Is there any way, on Ubuntu 9.04, to install Ruby 1.8 as ruby1.8 (or get rid of it altogether) and have Ruby 1.9 be the default ruby?
在Ubuntu 9.04上，有没有办法把Ruby 1.8安装成ruby1.8(或者干脆把它删掉)，让Ruby 1.9成为默认的Ruby呢?

I'm not really sure, but maybe this can help:
我不太确定，但也许这能帮上忙:
update-alternatives --config ruby
... and here's the non-interactive, scriptable, way:
…这是一种非交互式的，可脚本化的方式:
update-alternatives --set ruby /usr/bin/ruby1.9.1
You may find out about available alternatives and respective /usr/bin/... paths by doing:
您可以找到可用的替代方案和各自的/usr/bin/…路径通过:
update-alternatives --query ruby

This is where installation of ruby is heading for ubuntu servers. This should allow you to not only switch to a ruby version when needed, but also keep gems separated based on ruby versions, etc.
这就是ruby安装在ubuntu服务器上的地方。这不仅允许您在需要时切换到ruby版本，而且还可以根据ruby版本将gems分离，等等。

You can completely remove Ruby 1.8 too with:
您也可以完全删除Ruby 1.8与:
sudo apt-get remove libruby1.8 ruby1.8 ruby1.8-dev rubygems1.8
After that, you will only have Ruby 1.9 installed.
之后，您将只安装Ruby 1.9。

sudo \curl -L https://get.rvm.io | bash -s stable --ruby --rails
will install an up-to-date version of ruby (and rails), and allow you to avoid brokenness of Ubuntu's RVM, see https://*.com/a/9056395/497756.
将安装最新版本的ruby(和rails)，并允许您避免Ubuntu的RVM损坏，参见https://*.com/a/9056395/497756。
If you go this route, get rid of Ubuntu-installed versions and associated packages like bundle.
如果您采用这种方式，请删除ubuntu安装的版本和相关包(如bundle)。

Try this:
试试这个:
sudo apt-get install ruby1.9.1 rubygems1.9.1
or try building from source. this worked for me on ubuntu 9.04 and after a restart 1.9 was the standard ruby
或者尝试从源头上构建。这对我在ubuntu 9.04上是有效的，在重启1.9之后是标准的ruby
