为什么RVM宝石列表显示我没有安装的宝石？

Question

我在Dreamhost共享主机。我安装了RVM来运行Ruby 1.9.2，并创建了一个空的gemset来处理。我运行了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，我会得到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：

1. 如何创建一个真正的筒仓我的项目，一个宝石这是真正为空？
2. 如何摆脱当地宝石中的“无效gemspec”错误？因为如果我切换回rvm use 1.8.7，然后运行gem list我不要得到“无效的gemspec”错误！

打字rvm use ruby-1.9.2@MYGEMSET，然后运行which gem点~/.rvm/rubies/ruby-1.9.2-p290/bin/gem我认为这是正确的。

Answer 1

最有可能出现这种情况是因为全球宝石包含all宝石，尝试：

rvm 1.9.2@global gem list 

你可以用宝石列表比较这对只看到你的宝石：

rvm use 1.9.2 
diff --normal <(gem list) <(rvm 1.9.2@global gem list) | sed '/^[^<]/ d ; s/^< //' 

或仅使用GEM_HOME作为GEM_PATH：

GEM_PATH=$GEM_HOME gem list 

Answer 2

我相信rvm do gem list会列出所有红宝石（以及所有宝石）的宝石。如果你有rvm设置并且源代码正确，你应该可以使用所有的shell脚本（ruby，gem，bundle等），而不用rvm作为前缀。

使用正确的ruby版本+ gemset（即：rvm use ruby-1.9.2@MY_GEMSET）后，尝试gem list。如果这样会产生奇怪的结果，请查看which gem使用哪个宝石。

Answer 3

RVM做宝石列表已经过时

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信息检查是否使用了正确的红宝石和宝石。最好的做法是创建一个.rvmrc文件
