如何從rake任務中執行git commit/push

Question

我嘗試從Ruby rake任務中執行某些git命令時遇到以下問題（我嘗試過沒有bash --login -c並得到相同的結果）。

tmpid='TueJan26014125UTC2010' 
cmd=["git add .", 
    "git commit -a -m \'Migrate nanoc3 co output to gh-pages #{tmpid}\'", 
    "git push --force origin gh-pages:gh-pages" 
] 

FileUtils.chdir @gh_pages_repo_path.to_s do 
    puts `pwd` 
    cmd.each do |cmdi| 
     puts "bash --login -c '#{cmdi}'" 
     res=Kernel.send(:`, "bash --login -c '#{cmdi}'") 
     puts res 
    end 
end 

我這個輸出顯示工作目錄和混帳推失敗

/home/mv/Documents/Workspaces/scar/ruby/scar/gh-pages 
bash --login -c 'git add .' 

bash --login -c 'git commit -a -m 'Migrate nanoc3 co output to gh-pages TueJan26014125UTC2010'' 
# On branch master 
nothing to commit (working directory clean) 
bash --login -c 'git push --force origin gh-pages:gh-pages' 
error: src refspec gh-pages does not match any. 
error: failed to push some refs to 'git@github.com:hedgehog/scar.git' 
To prevent you from losing history, non-fast-forward updates were rejected. 
Merge the remote changes before pushing again. 
See 'non-fast forward' section of 'git push --help' for details. 

如果我運行相同的命令，隨即，從bash shell中（konsole的）所有收益罰款：

$ pushd /home/mv/Documents/Workspaces/scar/ruby/scar/gh-pages 
/usr/src ~ 
$ git add . 
$ git commit -a -m 'Migrate nanoc3 co output to gh-pages TueJan26014125UTC2010' 
[gh-pages 14cbe34] Migrate nanoc3 co output to gh-pages TueJan26014125UTC2010 
20 files changed, 100 insertions(+), 0 deletions(-) 
$ git push --force origin gh-pages:gh-pages

欣賞任何見解。

您可能想嘗試使用庫來爲您處理git調用。一個例子是ruby-git。
