无法使用捆绑安装在Mavericks上安装gem

我已经尝试了一段时间，在谷歌搜索，但没有运气。 进行bundle install ，出现以下错误。

An error occurred while installing json (1.8.3), and Bundler cannot continue.
Make sure that `gem install json -v '1.8.3'` succeeds before bundling.

我也已经运行xcode-select --install

gcc /usr/bin/gcc -> /usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/gcc-4.2

红宝石版本ruby 2.2.0p0

您似乎不接受许可。 尝试这个

sudo xcodebuild -license

Answer 2

经过一番尝试和错误，我能够解决此问题。 我必须先安装Rails 4.2.0。

首先，我尝试了gem install rails -v 4.2.0

得到了以下错误

This could take a while...

使用以下命令解决了问题

gem uninstall nokogiri libxml-ruby
gem install nokogiri
gem install rails -v 4.2.0
bundle install
