ruby - 为什么 RVM gem 列表显示我没有安装的 gem？

Question

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。我对它运行了 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，我会得到一长串 Dreamhost 提供的开箱即用的 gem。

[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，一个真正空的 gemset？
2. 如何消除本地 gems 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 我不会得到“无效的 gemspec”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 我认为是正确的。

Answer 1

很可能发生这种情况是因为全局 gemset 包含所有 gem，请尝试:

rvm 1.9.2@global gem list

您可以将其与 gem 列表进行比较以仅查看您的 gem :

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
