为什么RVM列表显示我没有安装的宝石？

Question

我是在梦想主机共享主持。我安装了RVM来运行Ruby1.9.2，并创建了一个可以使用的空宝石集。我在上面运行了gemset empty命令，以确保它是空的。

奇怪的是，如果我运行rvm gemset use MYGEMSET，然后运行rvm do gem list，我就会得到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. 如何为我的项目创建一个真正的筒仓，一个真正为空的宝石集？
2. 如何消除本地宝石中的“无效宝石规范”错误？因为如果我切换回rvm use 1.8.7，然后运行gem list，那么就不会得到“无效的get规范”错误！

编辑

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

Answer 1

这很可能是因为全局宝石集包含all - gems，请尝试：

rvm 1.9.2@global gem list

您可以将其与宝石列表进行比较，只查看您的宝石：

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

或者只使用GEM_HOME作为GEM_PATH

GEM_PATH=$GEM_HOME gem list

Answer 2

建议取消rvm do gem列表。

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

Answer 3

我相信rvm do gem list会为你所有的红宝石(和所有的宝石)列出宝石。如果您的rvm设置和来源正确，您应该能够使用所有的shell脚本(ruby、gem、bundle等)。而不以rvm作为前缀。

在您使用正确的ruby版本+ gem list集(即：rvm use ruby-1.9.2@MY_GEMSET)之后，请尝试使用它。如果这会产生奇怪的结果，请查看您在which gem中使用的gem。
