将自己写的gem发布到rubygems

 要发布到rubygems.org，你需要申请github帐户和rubygems.org帐户 

 通过http://rubygems.org/sign_up申请一个rubygems.org帐户

进入帐户信息编辑页面https://rubygems.org/profile/edit，有一个建立API Key访问指令的命令行

curl -u geda https://rubygems.org/api/v1/api_key.yaml > ~/.gem/credentials; chmod 0600 ~/.gem/credentials

rake release

中间会从github上取信息，可能会报错

error: SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed while

解决方法：

git config --global http.sslVerify false
#更新与发布

 Pushing gem to https://rubygems.org...
Repushing of gem versions is not allowed.
Please use `gem yank` to remove bad gem releases.
如发生上述错误,修改你的 lib/*/version.rb, 比如將版本從 0.0.1 改成 0.0.2
发布新版本:
rake build
rake install
gem push pkg/your.gem
