我正在尝试学习如何使用 GitHub 对我的工作进行版本控制。(我一个人工作,没有合作者,没有不同的分支机构,只是我在工作时备份我的工作。)我在 BitBucket.org 上建立了私有 Git 存储库。我使用 GitHub for OSX 作为我的 Git GUI。
但是,当我在硬盘驱动器上对本地 Git 存储库中的文件进行编辑时,然后使用 GitHub for OSX 尝试“提交和同步”,我收到此错误:
git: 'credential-osxkeychain' is not a git command. See 'git --help'.
git: 'credential-osxkeychain' is not a git command. See 'git --help'.

这是什么意思,我该如何解决它,以及如何避免将来得到它?
