ERROR: While executing gem ... (NoMethodError)
undefined method `invoke_with_build_args' for nil:NilClass

推荐答案
您需要安装zlib开发标头.
You need to install the zlib development headers.
xcode-select --install
现在在OS X 10.9中，按需安装了命令行开发工具.因此，运行此命令后，zlib和zlib-devel也应该可用.
In OS X 10.9, the command line developer tools are now installed on demand. So after running this also zlib and zlib-devel should be available.
