在圖形界面中，執行拉取操作時，出現下面的錯誤。
You asked to pull from the remote 'origin', but did not specify
a branch. Because this is not the default configured remote
for your current branch, you must specify a branch on the command line.
解決辦法：
Edit your .git/config
[branch "master"] remote = origin merge = refs/heads/master
Now you can simply git push and git pull.
