ruby - 避免镜像安装新发布的 gem

Bundler 1.3.0 刚刚发布（目前只有 10 人安装），但我只能安装一个 pre 版本，或者以前的版本。

我如何告诉 ruby​​gems 查看规范的存储库，而不是过时的镜像？

Answer 1

我从ruby​​gems.org下载了gem 文件，并使用.gem install path/to/gem/file

有人说他们是通过 安装的gem install bundler --pre，但我没有尝试。

Answer 2

在你的 Gemfile 中试试这个：

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"
