ruby – rake release失败(使用gem bundler)

我使用了bundler,它使用bundle gem命令创建了三个rake任务：

$rake -T
rake build    # Build blomming_api-0.3.7.gem into the pkg directory
rake install  # Build and install blomming_api-0.3.7.gem into system gems
rake release  # Create tag v0.3.7 and build and push blomming_api-0.3.7.gem to Rubygems

如果使用rake install在本地安装gem,那一切都很好：

$rake install
blomming_api 0.3.7 built to pkg/blomming_api-0.3.7.gem.
blomming_api (0.3.7) installed.

当我尝试发布时出现问题：

$rake release
blomming_api 0.3.7 built to pkg/blomming_api-0.3.7.gem.
Tagged v0.3.7.
Untagging v0.3.7 due to error.
rake aborted!
Couldn't git push. `git push  2>&1' failed with the following output:

fatal: No configured push destination.
Either specify the URL from the command-line or configure a remote repository using

    git remote add <name> <url>

and then push using the remote name

    git push <name>

(See full trace by running task with --trace)

不过我可以使用成功的gem push命令发布gem：

$gem push pkg/blomming_api-0.3.7.gem
Pushing gem to https://rubygems.org...
Successfully registered gem: blomming_api (0.3.7)

我认为问题出在git push远程配置上……
有没有想过帮我配置git让rake发布运行？

顺便说一下,我已经在/home/solyaris/.gem上配置了我的rubygems凭据
并且git push在github上运行正常.
我知道……我的git不情愿很大;-)
谢谢
