使用RVM安装Ruby后，全局宝石不可见

Question

我以通常的方式安装了rvm：

curl -L https://get.rvm.io | bash -s stable --ruby

在安装过程中显示了这些消息：

ruby-1.9.3-p286 - #configure
ruby-1.9.3-p286 - #download
(...)
ruby-1.9.3-p286 - #extract
ruby-1.9.3-p286 - #validate
ruby-1.9.3-p286 - #setup
'ruby' was not found, cannot install rubygems unless ruby is present (Do you have an RVM ruby installed & selected?)
Saving wrappers to '/home/rmaruszewski/.rvm/bin'.
ruby-1.9.3-p286 - #importing default gemsets (/home/rmaruszewski/.rvm/gemsets/)
Creating alias default for ruby-1.9.3-p286.
Recording alias default for ruby-1.9.3-p286.
Creating default links/files
Saving wrappers to '/home/rmaruszewski/.rvm/bin'.

"找不到'ruby'"消息是可疑的....

，当我致电gem list时，列表为空。

*** LOCAL GEMS ***

，但然后我致电rvm use ruby@global，然后致电gem list，我得到：

*** LOCAL GEMS ***
bundler (1.2.1)
rake (0.9.2.2)
rubygems-bundler (1.1.0)
rvm (1.11.3.5)

因此，显然，从"默认"宝石中看不到我的"全局"宝石。你能告诉我为什么吗？

这是"全局"宝石的rvm info的输出：

Answer 1

我认为我遇到了同一确切的问题，除了mac osx 10.7。

我是Ruby的新手。我正在通过Netuts教程（http://net.tutsplus.com/tutorials/ruby/singing-with-sinatra-the-recall-app-2/）。

我安装了RVM，升级到最新的Ruby（Mac带有1.8.7），设置RVM默认为1.9.3，已安装的Sinatra，DatamApper等irb或一个.rb文件，我得到" LoadError：无法加载此类文件-DatamApper"错误。

i GEM已安装了Data_mapper，这似乎有效，但是，这似乎是我不理解的某种配置问题。

我发布的是因为我看到与您的RVM（1.16.17）和Ruby（1.9.3-P286）的版本相同的版本，并且我在我的GEM列表中具有相同的RVM版本-Local-local（RVM 1.11.3.5）（RVM 1.11.3.5）。

不确定我如何拥有RVM 1.16.17，并且宝石说RVM 1.11.3.5。另外，RubyGems应该被"包含在1.9中"，但是在IRB中，如果我键入需要" RubyGems"，则返回false。

我讨厌成为n00b ...对不起，我没有答案。

您是否首先使用了Ruby：

rvm use ruby
