mac 下利用 octopress 搭建博客时挂在了 rake generate 这一步，有两个疑问求解答

按照教程来，安装brew，然后ruby什么的，环境都搭建好了。
我创建了几篇博客用rake preview在本地也可以预览，接下来按照这样的顺序
rake setup_github_pages
rake generate

到rake generate这一步的时候报错：
Generating Site with Jekyll
write source/stylesheets/screen.css
Configuration file: /Users/hf-27/octopress/_config.yml
Source: source
Destination: public
Generating...
done.
Auto-regeneration: disabled. Use --watch to enable.

使用rake --watch，也无济于事。
网上查的时候，怀疑是jekyll的问题，因为我用jekyll build命令时出现同样的问题,错误提示一模一样。

第二个疑问是，我没理会上面的问题，继续rake deploy，出现问题，此时我只是新建的几个博客，没有用git做其他操作(add commit都没有)，错误提示有两段比较重要的，其中一段是这样的：
Deploying branch to Github Pages
Pulling any updates from Github Pages

git pull <remote> <branch>

If you wish to set tracking information for this branch you can do so with:

git branch --set-upstream-to=origin/<branch> master

cd -
rm -rf _deploy/index.html

Copying public to _deploy
cp -r public/. _deploy
cd _deploy

另外一段错误提示是：
Pushing generated _deploy website

error: failed to push some refs to 'https://github.com/kobe1941/kobe1941.github.io.git'

我是指想搭个博客而已嘛，求各位帮忙解决这两个问题。

我操作的branch是source。

我安装的环境的版本：
hf-27deMac-mini:octopress hf-27$ gem --version
2.4.6
hf-27deMac-mini:octopress hf-27$ bundle --version
Bundler version 1.8.3
hf-27deMac-mini:octopress hf-27$ rake --version
rake, version 10.4.2
hf-27deMac-mini:octopress hf-27$ jekyll --version
jekyll 2.5.3

@zealic
@chloerei 1.我把github上的仓库删掉，重新弄了一遍，可能是之前添加ssh的时候没弄对，
2.关于第二个问题，我在这里找到了答案： http://stackoverflow.com/questions/19619280/octopress-pushing-error-to-github

现在可以使用正常了，Auto-regeneration: disabled. Use --watch to enable.这句话确实不是错误。

现在执行 rake deploy 依然会有
There is no tracking information for the current branch.
Please specify which branch you want to merge with.
See git-pull(1) for details

git pull <remote> <branch>

If you wish to set tracking information for this branch you can do so with:

git branch --set-upstream-to=origin/<branch> master

这个信息提示，我没理会，不影响使用。
