This is a duplicate of https://github.com/CocoaPods/CocoaPods/issues/5037 -- it's a bug in Ruby's FFI implementation that's fixed by newer (2.2.3+ I think) versions of ruby.

[iwasrobbed]

Missed that one, thanks @segiddins

[lanzaiyige]

I upgrade my ruby version at 2.2.0,but this problem still exist.

[iwasrobbed]

@lanzaiyige Ruby 2.2.3+ fixes it.

@iwasrobbed like you said, I upgrade my ruby version to 2.3.0, the problem resolved, thanks!
