我在Dreamhost共享主机上。我安装了RVM来运行Ruby 1.9.2，并创建了一个空的gemset来使用。我在它上面运行gemset empty命令以确保它真的是空的。
奇怪的是，如果我运行rvm gemset use MYGEMSET然后运行rvm do gem list，我会获得Dreamhost提供的一长串宝石。
[phantom]$ rvm do gem list
WARN: `rvm do gem list` is deprecated, use `rvm all do gem list` or `rvm 1.9.2 do gem list` instead.

我有两个问题：
rvm use 1.8.7然后运行gem list我不会收到“无效的gemspec”错误！修改
键入rvm use ruby-1.9.2@MYGEMSET，然后运行which gem指向我认为正确的~/.rvm/rubies/ruby-1.9.2-p290/bin/gem。
答案 0 :(得分：2)
rvm do gem list已弃用
rvm gemset list: List your gemsets
rvm gemset create your_gemset: Create a gemset
rvm gemset use your_gemset: Use a gemset
gem list: List current gemset gems
使用rvm info检查您使用的是正确的ruby和gemset。最佳做法是创建.rvmrc文件
答案 1 :(得分：2)
最有可能发生这种情况是因为全局gemset包含all个宝石，请尝试：
rvm 1.9.2@global gem list
你可以将它与宝石列表进行比较，只看你的宝石：
rvm use 1.9.2
diff --normal <(gem list) <( rvm 1.9.2@global gem list ) | sed '/^[^<]/ d ; s/^< //'
或仅将GEM_HOME用作GEM_PATH：
GEM_PATH=$GEM_HOME gem list
答案 2 :(得分：0)
我相信rvm do gem list将列出所有红宝石（以及所有宝石组）的宝石。如果你有正确的rvm设置和源代码，你应该能够使用所有的shell脚本（ruby，gem，bundle等等）而不用rvm作为前缀。
使用正确的ruby版本+ gemset（即：gem list）后尝试rvm use ruby-1.9.2@MY_GEMSET。如果这会产生奇怪的结果，请查看您使用which gem的宝石。
