我正在尝试让Travis CI建立一个多语言项目。 （这PR。）我遇到的问题是pod install步骤保持了segfaulting。
/Users/travis/.rvm/gems/ruby-2.0.0-p643/gems/json-1.8.3/lib/json/ext/parser.bundle: [BUG] Segmentation fault
ruby 2.0.0p645 (2015-04-13 revision 50299) [universal.x86_64-darwin15]
如果我按照common Travis build problems指南中的建议使用Ruby 1.9.3（使用language: ruby并在rvm: 1.9.3中设置.travis.yml），那么当我出现时会出现错误尝试安装CocoaPods。
++gem install cocoapods -v 0.32.1
...
ERROR: Error installing cocoapods:

答案 0 :(得分：0)
通过设置rvm: 2.2.3将Ruby的版本更改为2.2.3，为我解决了这个问题。
