使用 RVM 安装 Ruby 后全局 gemset 不可见

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'.

“'ruby' was not found”消息很可疑....

而且，当我打电话给gem list 时，列表是空的。

*** LOCAL GEMS ***

然后我打电话给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“default”gemset 中是不可见的。你能告诉我为什么吗？

这是 rvm info 对于“全局”gemset 的输出：

Answer 1

我想我遇到了同样的问题，除了 Mac OSX 10.7。

我是红宝石新手。我正在阅读 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），将 rvm 设置为默认为 1.9.3，gem 安装了 sinatra、datamapper 等，但是当我尝试在任一IRB 或 .rb 文件，我收到“LoadError: cannot load such file -- datamapper”错误。

我 gem 安装了 data_mapper ，这似乎可以工作，但是，这似乎是某种我不明白的配置问题。

我发帖是因为我看到 RVM (1.16.17) 和 ruby​​ (1.9.3-p286) 的版本与您相同，并且我的 gem 列表中的 RVM 版本相同 --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“包含”，但在 irb 中，如果我输入 require “rubygems”，它会返回 false。

我讨厌成为 n00b...抱歉，我没有答案。

您是否首先使用了红宝石：

rvm use ruby
