Rails 未使用正确版本的 Ruby [英] Rails not using correct version of Ruby
问题描述
新信息
rails 控制台 会发生这种情况:
Loading development environment (Rails 3.1.1)
ruby-1.9.2-p290 :001 > RUBY_VERSION
=> "1.8.7"
这里发生了一些非常奇怪的事情 - 提示显示 1.9.2 但 RUBY_VERSION 显示 1.8.7.
There's something really weird going on here - the prompt says 1.9.2 but RUBY_VERSION shows 1.8.7.
我正在使用 RVM，但我在 Ubuntu 上遇到 Rails 问题.
I'm using RVM, but I'm having problems with Rails on Ubuntu.
$ which ruby
/home/nick/.rvm/rubies/ruby-1.9.2-p290/bin/ruby
$rvm list
rvm rubies
=> ruby-1.9.2-p290 [ i686 ]
但是如果我做 gem env 我得到
But if I do gem env I get
RubyGems Environment:
- RUBYGEMS VERSION: 1.8.11
- RUBY VERSION: 1.8.7 (2011-06-30 patchlevel 352) [i686-linux]
- INSTALLATION DIRECTORY: /home/nick/.rvm/gems/ruby-1.9.2-p290
- RUBY EXECUTABLE: /usr/bin/ruby1.8
- EXECUTABLE DIRECTORY: /home/nick/.rvm/gems/ruby-1.9.2-p290/bin
当我运行 Rails 时，如果我执行 puts RUBY_VERSION 它会输出 1.8.7.
and when I run Rails, if I do puts RUBY_VERSION it outputs 1.8.7.
事实上，在 irb 中，RUBY_VERSION 给出了 1.9.2 但在 rails 控制台 中它给出了 1.8.7.
In fact, in irb, RUBY_VERSION gives 1.9.2 but in rails console it gives 1.8.7.
主要问题是当它到达我的 JSON 样式的散列文字时它失败了.
The main problem is that it's failing when it gets to my JSON-style hash-literals.
我尝试了各种卸载 rvm、rails、bundler 等的方法，但似乎没有任何效果.有什么想法吗?
I've tried various approaches of uninstalling rvm, rails, bundler, etc. but nothing seems to work. Any ideas?
这是rvm info的输出:

RUBYOPT: ""

但仍然 gem env 告诉我在 RubyGems 环境中 Ruby 版本是 1.8.7.我就是不明白.
but still gem env tells me that in the RubyGems Environment the Ruby version is 1.8.7. I just don't get it.
推荐答案
你应该像这样设置默认的 ruby:
You should set default ruby like:
rvm use 1.9.2 --default
这将使用 rvm one 覆盖系统安装的 ruby.
This will override system installed ruby with rvm one.
更新:
notme，谢谢你的评论
notme, thank you for remark
默认前双连字符对于设置默认红宝石很重要.
Leading double hyphen before default is significant to set default ruby.
下面列出了详细的&不言自明的例子，享受:
Below listed detailed & self-explained example, enjoy:
$ruby -v
ruby 1.8.7 (2008-08-11 patchlevel 72) [i686-linux]
$rvm list
rvm rubies
ruby-1.9.2-p290 [ i386 ]
$rvm use 1.9.2 --default
Using /usr/local/rvm/gems/ruby-1.9.2-p290
$rvm list default
Default Ruby (for new shells)
ruby-1.9.2-p290 [ i386 ]
$rvm use default
Using /usr/local/rvm/gems/ruby-1.9.2-p290
$ruby -v
ruby 1.9.2p290 (2011-07-09 revision 32553) [i686-linux]
$rvm list
rvm rubies
=> ruby-1.9.2-p290 [ i386 ]
