git pull报错“/usr/libexec/git-core/git-sh-setup: line 81: /usr/bin/sed: Bad file number”

git.exe pull -v --progress "origin"

/usr/libexec/git-core/git-sh-setup: line 81: /usr/bin/sed: Bad file number From http://gitlab.tools.xxxxxxx.com/xxxxxxx/mstats-monitor = [up to date] master -> origin/master C:\Program Files (x86)\Git/libexec/git-core\git-pull: line 268: /usr/bin/tr: Bad file number 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.

git did not exit cleanly (exit code 1) (2184 ms @ 2014/11/28 11:40:43)

有人知道原因嘛？
