Question

我按照通常的方式安装了RVM：

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

在安装过程中会显示以下消息：

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'.

“'红宝石'未找到”消息是可疑的......

而且，当我拨打gem list时，列表为空。

*** LOCAL GEMS ***

然后我致电rvm use ruby@global然后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)

所以，显然，我的“全局”gemset在“默认”gemset中是看不到的。你能告诉我为什么吗？

以下是“global”gemset的rvm info输出：

Answer 1

我认为除了Mac OSX 10.7之外我遇到了同样的问题。

我是红宝石的新手。我正在浏览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自带1.8.7），设置rvm默认为1.9.3，gem安装了sinatra，datamapper等，但当我尝试在任何一个中要求“datamapper”时IRB或.rb文件，我得到“LoadError：无法加载此类文件 - datamapper”错误。

我在gem上安装了data_mapper，这似乎有效，但是，这似乎是我不理解的某种配置问题。

我发帖是因为我看到了与RVM（1.16.17）和ruby（1.9.3-p286）相同的版本，我的宝石列表中有相同的RVM版本--local（rvm 1.11.3.5））。

不确定我如何拥有RVM 1.16.17并且gem说rvm 1.11.3.5。此外，rubygems应该在1.9中被“包含”，但在irb中如果我输入需要“rubygems”则返回false。

我讨厌成为一个n00b ...抱歉，我没有答案。

Answer 2

你是否首先使用了红宝石：

rvm use ruby

使用RVM安装Ruby后，全局gemset不可见
