我克隆了一个rails repo,我现在正试图捆绑安装
背景:
rails -v无法在Gemfile中列出的或本机上可用的任何gem源中找到gem'pg(> = 0)ruby'。 运行bundle install
以安装缺少的gem。

An error occurred while installing pg (0.18.3), and Bundler cannot continue.
Make sure that `gem install pg -v '0.18.3'` succeeds before bundling.
此时我运行gem install pg -v'0.18.3'
building native extensions. This could take a while...

我的gem文件底部有以下内容
# Use sqlite3 as the database for Active Record
group :development, :test do
gem 'sqlite3'
end
group :production do
gem 'rails_12factor'
gem 'pg'
end
我正在看下面这个问题 ,但似乎无法弄清楚等同于OSX。
