安装Ruby on Rails(via gem install rails)时,您可能会收到以下错误消息:
c:/Ruby193/include/ruby-1.9.1/ruby/ruby.h:109:14: error: size of array 'ruby_check_sizeof_voidp' is negative
还会有很多这样的警告:
c:/Ruby193/include/ruby-1.9.1/ruby/ruby.h:1333:12: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
还有一个错误
c:/Ruby193/include/ruby-1.9.1/ruby/missing.h:41:8: error: redefinition of 'struct timespec'
为什么会发生这种情况？如何成功安装Rails？
