我正在尝试将git-annex与Gitlab.com一起使用，但在尝试同步我的附件时遇到错误：
git annex sync --content
(merging origin/git-annex into git-annex...)
(recording state in git...)
GitLab: API is not accessible
Remote origin does not have git-annex installed; setting annex-ignore
This could be a problem with the git-annex installation on the remote. Please make sure that git-annex-shell is available in PATH when you ssh into the remote. Once you have fixed the git-annex installation, run: git config remote.origin.annex-ignore false
commit (recording state in git...)
ok
pull origin
ok
pull origin
ok
push origin
我可能做错了什么？
我使用的是最新版本的git附件（2015年8月5日）。
