Avoiding mirrors to install a freshly released gem

问题

Bundler 1.3.0 has just been released (only 10 people have installed it so far), but I can only install a pre version, or a previous version.

$ gem install bundler --version 1.3.0 --verbose

How can I tell rubygems to look at a canonical repository, rather than an out-of-date mirror?

回答1:

I downloaded the gem file from rubygems.org, and installed it with gem install path/to/gem/file.

Somebody said that they installed it by gem install bundler --pre, but I didn't try it.

回答2:

Try this in your Gemfile:

gem "nokogiri", :git => "git://github.com/tenderlove/nokogiri.git", :branch => "1.4"

git "git://github.com/wycats/thor.git", :tag => "v0.13.4"
gem "thor"

http://gembundler.com/git.html

Or try this gem:
