Question

我在 osx yosemite 10.10.1

中安装 rails 时出现此错误

 mezbah$ gem install rails --no-ri --no-rdoc
    ERROR:  Error installing rails:
        invalid gem: package is corrupt, exception while verifying: undefined method `size' for nil:NilClass (NoMethodError) in /Users/mezbah/.rbenv/versions/2.2.3/lib/ruby/gems/2.2.0/cache/nokogiri-1.6.6.2.gem
 mezbah$ gem install nokogiri
       ERROR:  Error installing nokogiri:

有什么想法吗？？

我得到了答案。我删除了以前的缓存，然后一切正常。

sudo rm /Users/username/.rbenv/versions/2.2.3/lib/ruby/gems/2.2.0/cache/nokogiri-1.6.6.2.gem

brew install libiconv   

gem install nokogiri
