为什么Bundler无法正确安装存储在Git仓库中的gem？

Bundler版本1.0.0.beta.2

  gemset:       "mmm"

bundle install 在我的 Gemfile 中似乎没有安装任何来自 git 的 gem。尽管 bundler 表示已成功下载和使用了 repo，但 gem list 却不同意。对于这个设置有什么问题的想法吗？

Answer 1

Bundler会将gem安装到自己的~/.rvm/gems/ruby-{version}/bundler/gems目录中。这与主要的gems目录是独立的，因此gem list命令无法列出它们，但bundle list命令可以。

根据Yehuda Katz的这篇文章：“在0.9版本中，我们通过将Bundler安装的gem放置到BUNDLE_PATH中来解决了这个问题，默认情况下为~/.bundle/#{RUBY_ENGINE}/#{RUBY_VERSION}。rvm不会将可执行文件或gem安装到root拥有的路径中，它会将BUNDLE_PATH设置为与GEM_HOME相同的位置。这意味着当使用rvm时，通过bundle install安装的gems会出现在gem列表中。” - asymmetric

嗨，BUNDLE_PATH 应该在哪里设置？ - coolesting
